    • Failed to mount error on Raid 5

      Greetings,

      I'm running .5.48 with a usb external hard drive. After the install, I loaded 3x4TB hard drives from my old raid 5 that was also part of OMV. I wiped those drives doing a quick wipe and then built the raid. Now, when I try to mount the raid, i get this:

      Error #6000:
      exception 'OMVException' with message 'Failed to mount '5144add1-94fd-4eff-8c54-23ca6309ec05': ' in /usr/share/openmediavault/engined/rpc/filesystemmgmt.inc:873
      Stack trace:
      #0 [internal function]: OMVRpcServiceFileSystemMgmt->mount(Array, Array)
      #1 /usr/share/php/openmediavault/rpcservice.inc(125): call_user_func_array(Array, Array)

      #3 /usr/sbin/omv-engined(495): OMVRpc::exec('FileSystemMgmt', 'mount', Array, Array, 1)
      #4 {main}

      Also noticed that the OS disk is now mounted as dev/SDD.

      I've seen other posts for this but no real solution. Does anyone have an idea why this is happening and the fix?

    • In the error message, you should have another error message above the textfield, we need this too.

      Also, you could try 'mount -a' via CLI to force mount the hard disk and see if that works.

    • I just thought about mount -a without /dev/md127 in the end, but ok.

      Please post the output of cat /proc/mdstat and mdadm --detail /dev/md127

    • So its a normal 2,5" hdd?

      Are you maybe using a custom kernel? I had someone on the IRC just an hour ago who had the exact same problem which we nailed down to a custom kernel which didn't had support for ACL enabled.

    • Try mkdir /mnt/test101 && mount -t ext4 /dev/md127 /mnt/test101 if it's an ext4 filesystem.
