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,

  • It responded like this;


  • 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.

    Please don't PM for support... Too many PMs!

  • Mount button is still disabled :(

  • I installed it on a clean flash disc with the openmediavault_2.1_i386.iso burned cd. I haven't done any customization during the install. I made secure wipe to all my 3 hdd and then built the raid5. Here is what i did after your last reply.
