Hi all I just saw that my log were filled with errors mentioning BTRFS. I am bit lost and hope someone could help me identify the problem.

 

The NVME drive is using XFS and is set as "cache", and I have 2 SATA SSDs using BTRFS set up as a separate cache "sata-raid" pool.

 

Note that for now, TRIM fails on the 2 SATA SSDs because my HBA card does not support it.

 

Below are the first occurrences of the errors. The diagnostics files are also attached.

 

Thank you so much for you help.

    Device is dropping offline, hence the btrfs errors, this can sometimes help, on the main GUI page click on the flash drive, scroll down to "Syslinux Configuration", make sure it's set to "menu view" (top right) and add this to your default boot option, after "append initrd=/bzroot" 

    nvme_core.default_ps_max_latency_us=0 pcie_aspm=off

    e.g.: 

    append initrd=/bzroot nvme_core.default_ps_max_latency_us=0 pcie_aspm=off


    Reboot and see if it makes a difference.

    Hi @JorgeB,

    Thank you so much. While I was waiting, I restarted (without making the change you suggest) and now my NVME drive is shown as "missing" by unraid.

    Would that be still useful to try and perform the changes to the syslinux config that you suggest ? FYI mine is as follows:

      

    default menu.c32
menu title Lime Technology, Inc.
prompt 0
timeout 50
label Unraid OS
  menu default
  kernel /bzimage
  append pcie_acs_override=downstream initrd=/bzroot
label Unraid OS GUI Mode
  kernel /bzimage
  append pcie_acs_override=downstream initrd=/bzroot,/bzroot-gui
label Unraid OS Safe Mode (no plugins, no GUI)
  kernel /bzimage
  append initrd=/bzroot unraidsafemode
label Unraid OS GUI Safe Mode (no plugins)
  kernel /bzimage
  append initrd=/bzroot,/bzroot-gui unraidsafemode
label Memtest86+
  kernel /memtest

     

    Thank you very much.

    Reboot is unlikely to bring it back, a power cycle should, unless it failed.

    Many thanks. The NVME drive is showing back after a power cycle.

    I will now see if the problem happens again.

    I wish you a very nice day.
