btrfs volume not mounted after reboot

  • Hi,
    I have a btrfs volume consisting of 5 disks, which also shows up under Storage / File Systems - but it is neither Mounted nor Referenced. Status is Online.


    When I select the row with the btrfs volume and click Mount, the web gui gives after some time error "communication failure" and I can hear disk activity on the server for a longer time. Applying the configuration changes does not (visually) change the result.





    Code
    root@openmediavault:~# blkid
    /dev/sda1: LABEL="SSD" UUID="01CBBD747F977740" TYPE="ntfs" PARTUUID="ba9937a6-01"
    /dev/sdb1: UUID="ba03e21d-5f3b-49d2-af51-b54fcbce4e4f" TYPE="ext4" PARTUUID="a38799b1-01"
    /dev/sdb5: UUID="a3b3e50f-365d-48fa-bf60-bff7c22fbc76" TYPE="swap" PARTUUID="a38799b1-05"
    /dev/sdc: UUID="dc7ca9ad-6af0-47e9-9c3a-860127d2c362" UUID_SUB="2c91c083-c7fe-49f4-9366-9c7bc11b25e5" TYPE="btrfs"
    /dev/sdd: UUID="dc7ca9ad-6af0-47e9-9c3a-860127d2c362" UUID_SUB="ff69f7f1-8f1c-415a-85c7-fb9ebf128b4f" TYPE="btrfs"
    /dev/sde: UUID="dc7ca9ad-6af0-47e9-9c3a-860127d2c362" UUID_SUB="a3055af1-c347-4271-80c8-4c496b08e4e1" TYPE="btrfs"
    /dev/sdf: UUID="dc7ca9ad-6af0-47e9-9c3a-860127d2c362" UUID_SUB="806046ca-6ef3-4e6c-9b47-411ba66bea20" TYPE="btrfs"
    /dev/sdg: UUID="dc7ca9ad-6af0-47e9-9c3a-860127d2c362" UUID_SUB="bea7c939-21ad-4528-82a7-76585a3858c1" TYPE="btrfs"


    Probably something with the configuration is messed up, but I don't know where to start. Can anyone give advice?


    Thanks

  • If I manually mount the drive on the command line with

    Code
    mount -v --source /dev/disk/by-id/ata-ST8000VN0022-2EL112_ZA15REZ0 --target /srv/dev-disk-by-id-ata-ST8000VN0022-2EL112_ZA15REZ0

    the system runs fine - except the GUI does not show the volume as Mounted. But I received an email:


    Status succeeded Service mountpoint_srv_dev-disk-by-id-ata-ST8000VN0022-2EL112_ZA15REZ0 Date: Mon, 03 Sep 2018 09:08:48 Action: alert Host: openmediavault Description: status succeeded (0) -- /srv/dev-disk-by-id-ata-ST8000VN0022-2EL112_ZA15REZ0 is a mountpointYour faithful employee,Monit


    Can mounting the volume be automized correctly?
