• Unraid OS version 6.12.0-rc1 available


    limetech

    The 6.12 release includes initial ZFS support in addition to the usual set of bug fixes, kernel, and package updates.

     

    Please create new topics here in this board to report Bugs or other Issues.

     

    As always, prior to updating, create a backup of your USB flash device:  "Main/Flash/Flash Device Settings" - click "Flash Backup".

     

    Note regarding plugins:  This release includes upgrading PHP from v7.4 to v8.2.3, necessary for continued PHP security updates. We recommend you upgrade all your plugins before updating the OS, and be aware that any plugin which hasn't been updated recently (with a comment about PHP 8 in the change logs) may not work correctly. You may want to uninstall that plugin until the author has had time to update it.  Plugin authors are aware of necessary changes and many plugins have already been updated.  If you encounter an issue with a plugin, please create a nice post in the plugins support topic.

     

    Special thanks to all our beta testers and especially:

     

    @bonienl for his continued refinement and updating of the Dynamix webGUI.

    @Squid for continued refinement of Community Apps and associated feed.

    @dlandon for continued refinement of Unassigned Devices plugin.

    @ich777 for continued support of third-party drivers, recommendations for base OS enhancements and beta testing.

    @JorgeB for rigorous testing of the storage subsystem and helping us understand ZFS nuances, of which there are many.

    @SimonF for curating our VM Manager and adding some very nice enhancements.

     

    Thanks to everyone above and our Plugin Authors for identifying and putting up with all the changes which came about from upgrading PHP from v7 to v8.

     

    Finally a big Thank You! to @steini84 who brought ZFS to Unraid via plugin several years ago.

     


    Version 6.12.0-rc1 2023-03-14

    If you created any zpools using 6.12.0-beta5 please Erase those pools and recreate.

     

    If you revert back from 6.12 to 6.11.5 or ealier, you have to force update all your Docker containers and start them manually after downgrading.  This is necessary because of the underlying change to cgroup v2 in 6.12.0-rc1.

    ZFS Pools

    New in this release is the ability to create a ZFS file system in a user-defined pool.  In addition you may format any data device in the unRAID array with a single-device ZFS file system.

     

    We are splitting full ZFS implementation across two Unraid OS releases.  Initial support in this release includes:

    • Support raid0, mirror, raidz1, raidz2 and raidz3 root profiles. Up to 4 devices in a mirror vdev. Multiple vdev groups.
    • Support removing single device: if device still present in server, 'wipefs' is used to clear the partition table.
    • Support replacing single missing device with a new device of same or larger size.
    • Support pool rename.
    • Pool names must begin with a lowercase letter and only contain lowercase letters, digits, the underscore and dash. Pool names must not end with a digit.
    • Non-root vdev cannot be configured in this release, however, they can be imported.
    • Pools created on other systems may or may not import depending on how the the pool was created. A future update will permit importing pools from any system.

     

    A ZFS pool has three variables:

    • profile - the root data organization: raid0, mirror, raidz1, raidz2, raidz3
    • width - the number of devices per root vdev
    • groups - the number of root vdevs in the pool

    At time of ZFS pool creation, the webGUI will present all topology options based on the number of devices assigned to the pool.

     

    Special treatment for root single-vdev mirrors:

    • A single-device ZFS pool can be converted to multiple-device mirror by adding up to 3 additional devices in one operation.
    • A 2-device mirror can be increased to 3-device by adding a single device; similarly a 3-device mirror can be increased to 4-device mirror by adding a single device.

     

    To add an additional root vdev, you must assign 'width' number of new devices to the pool at the same time. The new vdev will be created with the same 'profile' as the existing vdevs. Additional flexibility in adding/expanding vdevs will be provided in a future update.

     

    Pools created with the 'steini84' plugin can be imported as follows: First create a new pool with the number of slots corresponding to the number of devices in the pool to be imported. Next assign all the devices to the new pool. Upon array Start the pool should be recognized, though certain zpool topologies may not be recognized (please report).

     

    Mixed topologies are not supported. For example, a pool with both a mirror root vdev and a raidz root vdev is not recognized.

     

    Autotrim can be configured as "on" or "off" (except for single-device ZFS volumes in the unRAID array).

     

    Compression can be configured as "on" or "off", where "on" selects "lz4". Future update will permit specifying other algorithms/levels.

     

    When creating a new ZFS pool you may choose "zfs - encrypted", which, like other encrypted volumes, applies device-level encryption via LUKS. ZFS native encryption is not supported at this time.

     

    During system boot, the file /etc/modprobe.d/zfs.conf is auto-generated to limit the ZFS ARC to 1/8 of installed memory. This can be overridden if necessary by creating a custom 'config/modprobe.d/zfs.conf' file. Future update will include ability to configure the ARC via webGUI, including auto-adjust according to memory pressure, e.g., VM start/stop.

    btrfs pools

    Autotrim can be configured as "on" or "off" when used in a pool.

     

    Compression can be configured as "on" or "off". "on" selects "zstd". Future update to permit specifying other algorithms/levels.

    xfs

    Autotrim can be configured as "on" or "off" when used as a single-slot pool.

    Docker

    • CreateDocker: changed label "Docker Hub URL" to "Registry URL" because of GHCR and other new container registries becoming more and more popular.
    • Honor user setting of stop time-out.
    • Accept images in OCI format.
    • Add option to disable readmore-js on container table

    VM Manager

    If you enable copy/paste for virtual consoles you need to install additional software on the client in addition to the QEMU agent if that has been installed. Here is the location for spice-vdagent for both Windows and Linux. Note copy/paste function will not work with web spice viewer you need to use virt-viewer.

    • Add Serial option to vdisk.
    • Spice Bug fix for users with non standard GUI ports defined.
    • OVMF for QEMU: version stable202302
    • Fix for bus text.
    • Enable copy paste option for virtual consoles
    • Update Memory Backup processing for Virtiofs.
    • Fix lockup when no VMs are present
    • Add support for rtl8139 network model.
    • fix translation omission
    • added lock/unlock for sortable items
    • Fix for Spice Mouse if Copy paste enabled.

    Dashboard

    The webGUI Dashboard has been redesigned, and it is now possible to move elements (tiles) up and down and between columns. This allows the user to organize the tiles in any way they desire.  There is a small "lock" icon on the menu bar which must be clicked to enable this function.

     

    Note: The "lock" icon also appears on the Docker and VM pages and must be clicked to rearrange the startup order.

    Great work guys. looks like lots of good improvements.  Gonna love the customizable dashboard.

     

    I will have to read up on advantages of ZFS but can anyone point out some use cases that would make it more valuable to the normal unraid user that just has the disks formated in xfs/btrfs with single/dual parity?  Is read/write performance better with ZFS?

    Link to comment

    Installed on my test server and created a zfs pool, that created several errors in the log and the webui hung up in a sense, none of the disks were able to be assigned, and I could not delete any pools. I restarted and the server will not boot. Will grab logs and post a bug report tomorrow. Thanks for the release!

     

    Edit: I wiped and re-installed from the USB creator, clearly something was wrong. I set up a test pool from scratch and it works great.

    Tried to import a previously created raidz2 pool with l2arc and slog devices but it says that the filesystem is unmountable.  I'll try removing the l2arc and slog drives and then just importing the raidz2 pool.  Maybe after I can re-add them.

    This also just happened to me.  The server boots but the webui doesn't work.

     

    *on edit* was able to get it booting again by removing the config file for the pool that was causing the issue.

    So can i import my current ZFS pool into it? since i was using a user based addon to run it before?

    Please look at the changelog (first post):

    Quote

    Pools created with the 'steini84' plugin can be imported as follows: First create a new pool with the number of slots corresponding to the number of devices in the pool to be imported. Next assign all the devices to the new pool. Upon array Start the pool should be recognized, though certain zpool topologies may not be recognized (please report).

    There is a regression from the last beta, that one was importing pools with all special vdevs expect spares, possibly while trying to fix that it broke something else, so at the moment existing pools with cache, log, dedup, special and/or spare vdev(s) cannot be imported, hopefully this will be fixed for -rc2.

    Just I can't find where I can create a ZFS Pool? 

    I added 3 disks with zfs file system and there are 3 pools:

    In the main GUI page click "Add pool", assign the devices, then click on the first one and choose the pool filesystem and topology, start array and format the devices to create the pool.

    After trying out RC1, I cant log in over SMB on any device. I know the password is right, tried to reset it, but just gets access denied. Rolling back for now.

    Updated to 6.12.0 RC1, rebooted, All came up good. Restarted again, no Web GUI. - I couldn't even Ping the IP.   

    Rebooted into console mode with Web GUI, Web GUI doesn't work there either. - Ping starts working.

    Ran these commands:

    /etc/rc.d/rc.nginx restart - Errored out and said the service isn't started.

    /etc/rc.d/rc.nginx start - The service started

    /etc/rc.d/rc.nginx reload - reloaded successfully.

     

    Now i'm getting 502 bad gateway.

     

     

    Any suggestions?

    Anyone know how to set max arc cache size? I’m currently using the zfs_arc_max parameter and for some reason it’s saying at boot that it doesn’t exist. 

    Link to comment

    I am about to import a ZFS pool, assigned the 5 devices, no slog or any special, just 5 identical HDDs, carefully assigned and double checked the serial numbers with screenshots, as I have some more HDDs as UD but NTFS, not ZFS, and the previously unmountable ZFS devices show now as historical device in the UD.

    Just need to know, should I leave File system type to auto, or change it to ZFS RaidZ 1 group of 5 Devices, that reflect the configuration that my pool was previously through the plugin. Have no back up of the data on the pool, it is 80% full, wont be a happy day if I see an empty fresh pool after I hit apply.

    Cheers.

    It's in the release notes, create this file:

    /boot/config/modprobe.d/zfs.conf

    with the amount you want, e.g., this is for 64GB:

    options zfs zfs_arc_max=67060137984

    Note that with zfs on Linux ARC should not be set to a value larger than half of the total installed RAM, even if it's unused, since due to memory fragmentation it can end up exhausting the server RAM.

    You can leave it at auto, and if some reason the pool cannot be imported it won't be damaged, just post the diags.

    Aw I missed it...my test server has 256GB of RAM so that number is what I want. Thank you for the clarification, I totally missed that!
