  1. I ran across an article whose author claimed that on recent versions of qemu,  discard=unmap was functional on virtio disks.  So I did some testing.

     

    I have not run all permutations, but have tested:

      Unraid 6.9.2

      UEFI and Seabios VMs

      Q35-5.1 and i440fx-5.1 VMs

      Windows 10 and Windows 11 with the latest virtio drivers, virtio-win-0.1.196.iso

      Ubuntu 21.4

      raw and qcow2 vdisks

      vdisks on XFS and BTRFS disks

      vdisks with and without the copy-on-write attribute set

     

    In all cases, the virtio disk was functionally equivalent to a virtio-scsi disk.  On file deletion, windows unmapped blocks immediately.  Linux unmapped blocks after running fstrim.

  2. Been using a CP1500PFCLCD for years with the unraid apc daemon.  No problems, except you should set “Turn off UPS after shutdown” to no.  It doesn’t work correctly with the apc software.  Tried with NUT several years ago and  it didn’t work work with it either.

  3. Adding a container variable of type path, with container path and host path of /usr/bin (and access mode of read only for security) , would substitute the docker's /usr/bin with unraid's /usr/bin.  However, this would probably have negative consequences.  The files are probably be from different linux distros.  I tried it with a random docker, and it wouldn't even start.

  4. I'm running 6.8.1 with a 3-drive raid1 cache pool.  I've been getting Errors on Cache Pool messages, and many of the following in the logs:

        BTRFS error (device sdf1): error writing primary super block to device 1

        kernel: sd 7:0:0:0: [sdf] tag#15 UNKNOWN(0x2003) Result: hostbyte=0x04 driverbyte=0x00

        kernel: sd 7:0:0:0: [sdf] tag#15 CDB: opcode=0x2a 2a 00 1d 9b af c0 00 00 58 00

     

    The device still shows a green ball on the Main tab, but smartctl returns

        Short INQUIRY response, skip product id
        A mandatory SMART command failed: exiting. To continue, add one or more '-T permissive' options.

     

    I'm assuming that the drive needs replacement.

     

    My only use of cache is VM's and Dockers, and I have disabled both services, as well as temporarily disabling the mover job.

     

    I would like to remove the cache pool from the configuration until I can obtain a replacement.

     

    I assume that the procedure is to stop the array and unassign all of the cache drives, and start the array.   Then when the new drive arrives, reassign the 2 good drives and the replacement, and start the array.  Please confirm my procedure.

     

    I only have remote access to the server for the next few days.

     

    Thanks

    It's not the same model:

    WD80EFZX-68UW8N0 - 1st gen helium filled model

    WD80EFAX-68LHPN0 - 2nd gen helium filled model

    WD80EFAX-68KNBN0 - newer air filled model

     

    Most likely, that disk look fine, unless there's a firmware bug which I find very unlikely.

    I just purchased two WD80's. To my surprise, what arrived were WDC_WD80EFAX-68LHPN0's.  I thought all new stock was air filled.  Helium is a plus for me, they run a few degrees cooler.

    unRAID version (6.8.1) not supported.
    plugin: run failed: /bin/bash retval: 1

    Being marked for deletion, and cannot reinstall on 6.8.1

    Its for this kind of issue that binhex isolated preclear in a docker.

    Just a general plex question ... i have set up a 'basic' plex server which is working just fine for local content only. I have been given a plexpass gift for xmas. How (can?) i integrate it into my existing server with minimal fuss?

    Once the plexpass is associated with your plex account, connect to your plex server using the web interface.  Logout of your plex account, then login again.  You’re done.  You now have all the features of plexpass.  Binhex’s plexpass docker gives you access to beta releases, not additional features.

  8. I'm running 6.6.7.  After running preclear, I am attempting to format a new 8TB drive.  I updated UD, installed UD Plus, and enabled Destructive Mode.  Clicked the red X, and entered Yes to remove the partition.  The log says that the partition is being removed, but it's not.  The red X comes back.

     

    fdisk -l shows that the partition still exists.

    Running parted returns "parted: error while loading shared libraries: libreadline.so.8: cannot open shared object file: No such file or directory".

     

    I tried removing UD and UD Plus, removing their plugin folders in flash/config/plugins, rebooting, and reinstalling.  Same result.

     

    Any ideas?

  9. I'm recording to a local drive on the MC pc.  Weekly, I am moving the recordings to unraid.  They never exist in both places at the same time.  After moving recordings, I need to restart the Windows Media Center Receiver Service so MC registers the change in the location of the recordings.

     

    Keep in mind that with your method, you are asking unraid to do something that it was never designed to do - receive data on a real-time basis.  The more simultaneous recordings that you do, and other things you may have running on on the server (plugins, dockers, VMs), the more difficult it will be for unraid to keep up.  The forums on www.thegreenbutton.tv have several threads on user experiences recording to a NAS.

     

    In the future, I am going to attempt to run Win7 MC as a VM on unraid.  And I'll either direct recordings to a dedicated Unassigned Devices drive, or pass through a physical drive to the VM for recordings.  In my house, all sh*t breaks loose if recordings are corrupted.

  10.   I've always been reluctant to try your method, except on my test MC server.  Especially with reports of array slowness in 6.7.x.  I record locally, then weekly, copy the recordings to Unraid, and remove them from local storage.  At the very least, consider limiting your recordings share to one disk, and have the link reference \\server\diskx\sharename rather than \\server\sharename, bypassing the overhead of the Fuse file system. 

     

    There's no problem having MC use unc paths to previously recorded content.  Its only the recording drive that needs the mklink trick.

     

    Nothing else comes to mind about using MC with Unraid.

  11. The following is from Windows 7 MC.

     

    In MC, go to Tasks | Settings | TV | Recorder | Media Libraries | Remove folders from library.  Verify that you do not have a reference to the recordings share on Unraid.  If you do, delete it.  Media Center should only know about your local drive, which is linked to the share.  It won't show up in this list because its the recording drive).  If MC knows about both, you'll show the duplicate recordings.

    Just a bit of education here, please keep in mind guys Plex Pass gives you early access to features, but it also gives you lovely early access to bugs as you have all seen, if you want to minimise this happening in the future then run binhex/plex instead, you still get access to all the plex pass additional stuff with a reduced risk of stuff blowing up in your face, the option is of course yours, i know which version im running and it aint this one 🙂

    @binhex, consider adding this information to the first post.  It will help new users decide which docker to use.

    hmm so custom bridge seems to have a limitation/bug, if you choose custom bridge then it looks like you cannot define both host and container port, so yor only option is default bridge (or host of course).

    For experimentation, I'm running two Plex dockers (one LinuxServer and one Binhex), using different appdata folders.  Since you can't change the port that Plex listens on (38400), I needed to assign a different  IP address to one of the dockers.  So the Binhex docker is running on Custom:br0, and a fixed IP address.  br0 is a Linux bridge, not a Docker bridge, so port mappings are not required. Its like Host mode.

     

    I'm still on 6.6.7, but that shouldn't matter.
