6.9.0

Version 6.9.0 2021-02-27​

Summary of New Features

Multiple Pools​

This feature permits you to define up to 35 named pools, of up to 30 storage devices per pool.  Pools are created and managed via the Main page.

  • Note: A pre-6.9.0 cache disk/pool is now simply a pool named "cache".  When you upgrade a server which has a cache disk/pool defined, a backup of config/disk.cfg will be saved to config/disk.cfg.bak, and then cache device assignment settings are moved out of config/disk.cfg and into a new file, config/pools/cache.cfg.  If later you revert back to a pre-6.9.0 Unraid OS release you will lose your cache device assignments and you will have to manually re-assign devices to cache.  As long as you reassign the correct devices, data should remain intact.

When you create a user share or edit an existing user share, you can specify which pool should be associated with that share.  The assigned pool functions identically to the current cache pool operation.

Something to be aware of: when a directory listing is obtained for a share, the Unraid array disk volumes and all pools which contain that share are merged in this order:

pool assigned to share

disk1

:

disk28

all the other pools in strverscmp() order.

A single-device pool may be formatted with either xfs, btrfs, or (deprecated) reiserfs.  A multiple-device pool may only be formatted with btrfs.  A future release will include support for multiple "Unraid array" pools, as well as a number of other pool types.

  • Note: Something else to be aware of: Let's say you have a 2-device btrfs pool. This will be what btrfs calls "raid1" and what most people would understand to be "mirrored disks". Well, this is mostly true in that the same data exists on both disks but not necessarily at the block-level.  Now let's say you create another pool, and what you do is un-assign one of the devices from the existing 2-device btrfs pool and assign it to this pool.  Now you have x2 single-device btrfs pools.  Upon array Start user might understandably assume there are now x2 pools with exactly the same data.  However, this is not the case. Instead, when Unraid OS sees that a btrfs device has been removed from an existing multi-device pool, upon array Start it will do a wipefs on that device so that upon mount it will not be included in the old pool. This of course effectively deletes all the data on the moved device.

Additional btrfs balance options​

Multiple device pools are still created using btrfs raid1 profile by default.  If you have 3 or more devices in a pool you may now rebalance to raid1c3 profile (x3 copies of data on separate devices).  If you have 4 or more devices in a pool you now rebalance to raid1c4 (x4 copies of data on separate devices).  We also modified the raid6 balance operation to set meta-data to raid1c3 (previously was raid1).

However, we have noticed that applying one of these balance filters to a completely empty volume leaves some data extents with the previous profile.  The solution is to simply run the same balance again.  We consider this to be a btrfs bug and if no solution is forthcoming we'll add the second balance to the code by default.  For now, it's left as-is.

SSD 1 MiB Partition Alignment​

We have added another partition layout where the start of partition 1 is aligned on a 1 MiB boundary. That is, for devices that present 512-byte sectors, partition 1 will start in sector 2048; for devices with 4096-byte sectors, in sector 256.  This partition type is now used when formatting all unformatted non-rotational storage (only).

It is not clear what benefit 1 MiB alignment offers.  For some SSD devices, you won't see any difference; for others, perhaps big performance difference.  LimeTech does not recommend re-partitioning an existing SSD device unless you have a compelling reason to do so (or your OCD just won't let it be).

To re-partition a SSD it is necessary to first wipe out any existing partition structure on the device.  Of course, this will erase all data on the device.  Probably the easiest way to accomplish this is, with array Stopped, identify the device(s) to be erased and use the 'blkdiscard' command:

blkdiscard /dev/xxx  # for example /dev/sdb or /dev/nvme0n1 etc

WARNING: be sure you type the correct device identifier because all data will be lost on that device!

Upon next array Start the device will appear Unformatted, and since there is now no partition structure, Unraid OS will create it.

  • Note: If you want to re-partition your SSD-based cache disk/pool and preserve data, please consider posting on the Unraid Community Forum for assistance with your particular configuration. Refer also to this post in the Prerelease board.

SMART handling and Storage Threshold Warnings​

There is a configuration file named config/smart-one.cfg which stores information related to SMART, for example, the controller type to be passed to smartctl for purposes of fetching SMART information.  Also stored in that file are volume warning and critical free space thresholds.  Starting with this release, these configuration settings are handled differently.

In the case of SMART configuration, settings are saved by device-ID instead of by slot-ID.  This permits us to manage SMART for unassigned devices.  It also permits SMART configuration to "follow the device" no matter which slot it's assigned to.  The implication however, is that you must manually reconfigure SMART configuration for all devices which vary from default.

The volume warning and critical space threshold settings have been moved out of this configuration file and instead are saved now in config/disk.cfg (for the Unraid array) and in the pool configuration files for each pool.  The implication is that you must manually reconfigure these settings for all volumes which vary from default.

After upgrading you may receiving a notification such as: Notice [TOWER] - Disk 1 returned to normal utilization level. As described above, all of your SMART configuration settings were reset to default. Visit Settings -> Disk Settings to review the defaults, and override for individual drives on Main -> Disk X -> Settings.

Better Module/Third Party Driver Support​

Recall that we distribute Linux modules and firmware in separate squashfs files which are read-only mounted at /lib/modules and /lib/firmware.  We now set up an overlayfs on each of these mount points, making it possible to install 3rd party modules using the plugin system, provided those modules are built against the currently running kernel version. In addition, we define a new directory on the USB flash boot device called config/modprobe.d the contents of which are copied to /etc/modprobe.d early in the boot sequence before the Linux kernel loads any modules.

This technique is used to install the Nvidia driver (see below) and may be used by Community Developers to provide an easier way to add modules not included in base Unraid OS: no need to build custom bzimage, bzmodules, bzfirmware and, bzroot files!

Passing Parameters to Modules​

The use of conf files in config/modprobe.d may be used to specify options and pass arguments to modules.

As an example: at present we do not have UI support for specifying which network interface should be "primary" in a bond; the bonding driver simply selects the first member by default.  In some configurations, it may be useful to specify an explicit preferred interface, for example, if you have a bond with a 1Gbit/s (eth0) and 10Gbit/sec (eth1) interface.

Since setting up the bond involves loading the bonding kernel module, and you can specify which interface to set as primary using this method:

Create a file on the flash: config/modprobe.d/bonding.conf which contains this single line, and then reboot:

options bonding primary=eth1

After reboot you can check if it worked by typing this command:

cat /proc/net/bonding/bond0

where you should see the selected interface show up as "Primary Slave".

Nvidia Driver​

The goal of creating squashfs overlays mounted at /lib/modules and /lib/firmware, along with providing a mechanism for defining custom module parameters, is to provide a way of integrating third-party drivers into Unraid OS without requiring custom builds of the bz* files. One of the most popular third-party drivers requested for Unraid OS is Nvidia's GPU Linux driver. This driver is required for transcoding capability in Docker containers. Providing this driver as a plugin for Unraid OS has required a lot of work to set up a dev environment, compile the driver and tools, and then unpack bzmodules, add the driver, create new bzmodules, and then finally replace in USB flash root directory. This work has been accomplished by Community members @chbmb, @bass_rock, and others. Building on their work, along with member @ich777 we now create separate Nvidia driver packages built against each new Unraid OS release that uses a new kernel, but not directly included in the base bz* distribution.

A JSON file describing the driver version(s) supported with each kernel can be downloaded here:

https://s3.amazonaws.com/dnld.lime-technology.com/drivers/releases.json

Each driver package includes the Nvidia Linux GPU driver along with a set of container tools.  The container tools include:

nvidia-container-runtime
nvidia-container-toolkit
libnvidia-container

These tools are useful in facilitating accelerated transcoding in Docker containers.  A big Thank You! to Community member @ich777 for help and for providing the tools. @ich777 has also provided a handy plugin to facilitate installing the correct driver.

The inclusion of third-party modules into Unraid OS using the plugin system is still a work-in-progress. For example, another candidate would be to replace the Linux in-tree Intel ethernet drivers with Intel's custom Linux drivers.

Docker​

It's now possible to select different icons for multiple containers of the same type.  This change necessitates a re-download of the icons for all your installed docker applications.  A delay when initially loading either the Dashboard or the Docker tab while this happens is to be expected prior to the containers showing up.

We also made some changes to add flexibility in assigning storage for the Docker engine. This is configured using the Settings/Docker Settings/Docker data root setting. This lets you select how to keep the Docker persistent state (image layers):

  • In a btrfs-formatted vdisk loopback-mounted at /var/lib/docker.  In this case the name of the image file must be 'docker.img'.
  • In an xfs-formatted vdisk loopback-mounted at /var/lib/docker.  In this case the name of the image file must be 'docker-xfs.img'.
  • In a specified directory which is bind-mounted at /var/lib/docker. Further, the file system where this directory is located must either be btrfs or xfs.

Docker will use either the 'btrfs' storage driver in the case of btrfs-formatted vdisk/directory, or the 'overlay2' storage driver in the case of xfs-formatted vdisk/directory.

Implemented as follows: First, rc.docker will detect the type of file system mounted at /var/lib/docker. We now support either btrfs or xfs and the docker storage driver is set appropriately.

Next, mount_image is modified to support a loopback file formatted either with btrfs or xfs depending on the suffix of the loopback file name.  For example, the file name ends with .img, as in docker.img then we use mkfs.btrfs.  If file name ends with -xfs.img, as in docker-xfs.img then we use mkfs.xfs.

In addition, we added the ability to bind-mount a directory instead of using a loopback.  If the file name does not end with .img then the code assumes this is the name of a directory (presumably on a share) that is bind-mounted onto /var/lib/docker.  For example, if /mnt/user/system/docker/docker then we first create, if necessary the directory /mnt/user/system/docker/docker.  If this path is on a user share we then "de-reference" the path to get the disk path which is then bind-mounted onto /var/lib/docker.  For example, if /mnt/user/system/docker/docker is on "disk1", then we would bind-mount /mnt/disk1/system/docker/docker.  Caution: the share should be cache-only or cache-no so that 'mover' will not attempt to move the directory, but the script does not check this.

Virtualization​

We integrated changes to the Tools -> System Devices page made by user @Skitals with refinements by user @ljm42. You can now select PCI devices to isolate from Linux upon boot simply by checking some boxes.  This makes it easier to reserve those devices for assignment to VM's.  This technique is known as stubbing (because a stub or dummy driver is assigned to the device at boot preventing the real Linux driver from being assigned).

One might wonder, if we can blacklist individual drivers why do we need to stub those devices in order to assign to VM's?  The answer is: you can.  But, if you have multiple devices of the same type, where some need to be passed to a VM and some need to have the host Linux driver installed, then you must use stubbing for the devices to pass to VM's.

Note: If you had the VFIO-PCI Config plugin installed, you should remove it as that functionality is now built-in to Unraid OS 6.9.  If you had manually stubbed devices by modifying your Syslinux file, consider switching to the new method as described in the vfio-pci guide.

Multi-Language Support​

Another exciting new feature in Unraid 6.9 is the ability to download language packs and use the Unraid OS in a number of different languages.

A huge amount of work and effort has been implemented by @bonienl to provide multiple-language support in the Unraid OS Management Utility, aka, webGUI.  Currently, English, Spanish, French, German, Dutch, Arabic, Simplified Chinese, Portuguese and Polish are available and several others are in the works.

Thanks to @Squid, language packs are installed via the Community Applications plugin - look for a new category entitled Language.

  • Note: Community Applications must be up to date to install languages.  For additional detail, see here.

Each language pack exists in public Unraid organization github repos. Interested users are encouraged to clone and issue Pull Requests to correct translation errors.  Language translations and PR merging is managed by @SpencerJ.

For more info on Multi-Language Support, please check out our guide.

We have also added an Unraid Community Forum Multi-Language Section.

Other​

GPU Driver Integration​

Unraid OS now includes selected in-tree GPU drivers: ast (Aspeed), i915 (Intel), amdgpu and radeon (AMD).  For backward compatibility, these drivers are blacklisted by default via corresponding conf files in /etc/modprobe.d:

/etc/modprobe.d/ast.conf
/etc/modprobe.d/i915.conf
/etc/modprobe.d/amdgpu.conf
/etc/modprobe.d/radeon.conf

Each of these files has a single line that blacklists the driver, preventing it from being loaded by the Linux kernel.

It is possible to override the settings in these files by creating a custom conf file in the config/modprobe.d directory on your USB flash boot device.  For example, to un-blacklist the amdgpu driver create an empty file by typing this command in a Terminal session:

touch /boot/config/modprobe.d/amdgpu.conf

This only needs to be done once, it does not need to be added to your go script.

In 6.9.1, if your go script contains a modprobe command for your GPU and/or a command to fix the permissions on /dev/dri, you should remove them:

modprobe amdgpu
chmod -R 777 /dev/dri

In 6.9.0, if the docker you are using is unable to access the GPU, add/keep this line to your go script:

chmod -R 777 /dev/dri

but remove this one:

modprobe amdgpu

Linux Kernel​

We are using LTS (Long Term Supported) kernel: version 5.10.x.

New features enabled in the kernel:

  • WireGuard module
  • iScsi Target module
  • USB/IP module

These out-of-tree drivers are included:

  • QLogic QLGE 10Gb Ethernet Driver Support (from staging)
  • RealTek r8125: version 9.003.05 (included for newer r8125)
  • HighPoint rr272x_1x: version v1.10.6-19_12_05 (per user request)

Note that as we update the Linux kernel, if an out-of-tree driver no longer builds, it will be omitted.

These drivers are omitted:

  • Highpoint RocketRaid r750 (does not build)
  • Highpoint RocketRaid rr3740a (does not build)
  • Tehuti Networks tn40xx (does not build)

If you require one of these drivers, please create a Bug Report and we'll spend some time looking for alternatives.  Better yet, pester the manufacturer of the controller and get them to update their drivers.

Base Packages​

All updated to latest versions.  In addition, Linux PAM has been integrated.  This will permit us to install 2-factor authentication packages in a future release.

SAS Spinning Control​

We should also now be able to properly support SAS device spin-up/down (finally) and with extraordinary help from @doron we are almost there.  SAS devices are generally designed for enterprise environments where device spin-down is rare, and many devices have inconsistent behavior surrounding this functionality.  This release itself does not include SAS device spin handling built-in but @doron is providing a plugin where we continue to address some nagging details.

SSH Improvements​

There are changes in /etc/ssh/sshd_conf to improve security (thanks to @Mihai and @ljm42 for suggestions):

  • only root user is permitted to login via ssh (remember: no traditional users in Unraid OS - just 'root')
  • non-null password is now required. To set a password go to the Users tab (or Settings -> Users, depending on your configuration), then choose the "root" user, type a complex password twice and press CHANGE (not RESET)
  • non-root tunneling is disabled

In addition, upon upgrade we ensure the config/ssh/root directory exists on the USB flash boot device; and, we have set up a symlink: /root/.ssh to this directory.  This means any files you might put into /root/.ssh will be persistent across reboots.

So, if you had previously added commands to your go script to copy authorized_keys and other files to /root/.ssh, you should remove those commands and simply put the files in config/ssh/root, then reboot.

Note: if you examine the sshd startup script /etc/rc.d/rc.sshd, upon boot all files from the config/ssh directory are copied to /etc/ssh (but not subdirs).  The purpose is to restore the host ssh keys; however, this mechanism can be used to define custom ssh_conf and sshd_conf files.

"unexpected GSO errors"​

If your system log is being flooded with errors such as:

Feb 20 09:09:21 Tower kernel: tun: unexpected GSO type: 0x0, gso_size 31, hdr_len 66

You need to edit each VM and change the model type for the Ethernet bridge from virtio to virtio-net.  In most cases this can be accomplished simply by clicking Update in "Form View" on the VM Edit page.  For other network configs it may be necessary to directly edit the xml.  Example:

<interface type='bridge'>
  <mac address='xx:xx:xx:xx:xx:xx'/>
  <source bridge='br0'/>
  <model type='virtio-net'/>
  <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
</interface>

"noVNC encountered an error"​

If you get a noVNC encountered an error message after upgrading, please clear your browser cache.

AFP support has been removed​

Even Apple is moving away from this protocol.

For best interoperability with macOS, and to export a share for Time Machine purposes, please ensure "Settings/SMB Settings/Enhanced macOS interoperability" is set to "Yes".
