    Parity Disk Rebuild – Troubling Syslog Messages

    in General Support

    Posted

    Running 6.12.8

    My array has 2 parity disks. I was in the process of rebuilding parity1 onto a larger disk. About half way through, I paused the rebuild to do some significant array access. Upon resuming the rebuild, the following showed in the syslog.

      

    Apr  8 22:04:41 Tower7 emhttpd: writing GPT on disk (sdj), with partition 1 byte offset 32KiB, erased: 0

    The rebuild completed successfully. I now need to determine if the contents of parity1 are valid. Since a non-correcting parity check would take almost a full day, I’m looking for an opinion as to the condition of parity1. If it is thought it is valid, I will do the non-correcting parity check. If not, I assume the way to proceed is to stop the array, wipe parity1 and redo the rebuild without pausing.

    Announcing New Unraid OS License Keys

    in Announcements

    Posted

    A significant portion of the value of unraid comes from the awesome collection of plugins and dockers created by the community.  In the long term, it will be almost impossible for those creators to support older versions of unraid.  In fact CA itself will no longer support the very stable 6.11.5. So most people actively using unraid will be forced to keep upgrading.

    [Plugin] Parity Check Tuning

    Just an FYI

     

    Getting a lot of these in the syslog

     

    Jan 30 12:36:21 Tower7 Parity Check Tuning: ERROR: marker file found for both automatic and manual check P Q

     

    I had an unclean shutdown.  The array is set to not auto-start.  After power cycling the server, I unchecked the box to correct parity, before starting the array.  A correcting parity check started anyway.

    Exfat doesn't support extended attributes and you are probably running into a limitation of the exfat file system.

    Thanks for the insight.  I did some additional testing.

     

    Client access to a UD share on exFat over smb is flakey if "Enhanced macOS interoperability" is enabled.  I have not observed this problem with any other partition type, including FAT32, which also doesn't support extended attributes.

     

    Manually editing the share's samba config, removing streams_xattr, and restarting samba seems to resolve the issue.

    I am having trouble renaming folders on exFat formatted UD mounted disks.  This is an example from Windows 10, although MacOS and Ubuntu are having issues as well.  I believe this is a recent problem, since I am often using exFat disks in UD since they are OS agnostic.

    Unraid 6.11.5 or 6.12.6

    UD 2023.12.15

    UD Plus 2023.11.30

    The share is public.

    Recycle Bin (vfs recycle) for SMB Shares

    in Plugin Support

    Posted · Edited by aim60

    I’m running 6.11.5, and after updating the plugin to 2023.02.20, I’m still having instances of folders in the recycle bin with their files missing.  However, my usage is probably uncommon.  My apps are configured to use user shares, but interactively, I use disk shares.

     

    During testing, deletes were done from a Windows client.  In all test cases, I am deleting:

      \\Servername\DiskOrPoolName\UserShare\FolderWithFile

     

    If the user share resides on an array disk (they are all Use cache pool=no), the folder and file show up in the disk’s .Recyele.Bin folder as expected.

     

    If the user share resides on the cache pool (they are all Use cache pool=only), the folder appears in the pool’s .Recycle.Bin without the file.

     

    The strange thing is, during testing I created a new user share in the cache pool, and it is working as expected.

     

    None of my other pools had previously defined user shares, and newly defined shares work ok.

    [Support] binhex - qBittorrentVPN

    @binhex, FYI

    Trying to explicitly specify

       Repository        binhex/arch-qbittorrentvpn:1.31.1.6733-1-01

    fails with

      Unable to find image 'binhex/arch-qbittorrentvpn:1.31.1.6733-1-01' locally
      docker: Error response from daemon: manifest for binhex/arch-qbittorrentvpn:1.31.1.6733-1-01 not found: manifest unknown:

      manifest unknown.

    Building with :latest works fine, which assume pulls the same version.

    Try these commands

    I've experimented with 

      echo '1' > /sys/block/sdX/device/delete

    and it gave me a warm and fuzzy before powering off a device.  But sometimes I wanted to remount the device without unplugging it first.  However, it had disappeared completely.  Even doing an UD Refresh Disks wouldn't bring it back.

     

    Research lead me to

      echo 1 > /sys/class/scsi_device/<scsi bus>/device/rescan

    which was successful.  But there was no way to tell which bus the disk was on unless you noted it before the device delete.  If you implement the above, please include a way to bring back the disk.

    [Plugin] USB_Manager

    Are you talking about Libvirt hotplug plugin or my hot plug as part of USB Manager

    Thanks for the screenshot.  Never noticed the USB Manager Hotplug section on the VMs page.  Since discovering that with USB Manager, I can use both of my licensed flash drives (with the same vendor id) at the same time, I haven't gone back to Libvirt hotplug.

     

    I found this, https://gitlab.com/libvirt/libvirt/-/issues/261

      It looks like the hotplug cdrom on a usb bus was never implemented.  There was a commit 3 weeks ago.

     

    Since cdroms are read-only, there might not be a conflict with ud.  And ud doesn't currently mount vdisks, although it would be a useful feature.

     

    Think about a usb mounted vdisk as a virtual external hard drive.  It could be plugged into any vm, and with ud enhancement, could be mounted on the host.  Not every vm has network access to the host.
