Cannot Mount FileSystem After Building Raid5

  • Hi,


    I'm new to OMV (Version 2.1.17). I Googled for this issue and also check this forum but the solutions offered did not solve my problem. What I did step by step is,


    1. Wiped my all 3 physical disk (all of 3 are same products) securely. (Took about 9 hours)
    2. Built a software Raid5
    3. Created a ext4 filesystem belonging to my Raid5.


    During this period, everything was ok and with no error messages. But, the mount button in filesystem menu is still disabled. I tried all the filesystems too... I tried to mount the raid via bash, but still can't be able to change the state of mount button.


    I need your advice. I can an ssh connection for you to check also...


    Thanks,

    What about:


    cat /etc/fstab
    mount /dev/md0

    omv 7.0-32 sandworm | 64 bit | 6.5 proxmox kernel

    plugins :: omvextrasorg 7.0 | kvm 7.0.9 | compose 7.0.9 | cputemp 7.0 | mergerfs 7.0.3

    According to the output, OMV doesn't know about the filesystem on the array yet. Try the following (assuming there is no data on the array):


    dd if=/dev/zero of=/dev/md0 bs=512 count=10000
    mkfs.ext4 /dev/md0


    Then try to mount in the filesystems tab.

    omv 7.0-32 sandworm | 64 bit | 6.5 proxmox kernel
