    • Failed to mount Filesystem

      Hi,
      I just installed OMV on my BananaPi M2 and connected two 5TB drives to it.
      I wiped both from the web interface and created a Linear Raid. Then I created a filesystem (ext4) which I cannot mount. I get the following error:

      Source Code

      1. Failed to mount 'cf7cb48e-ca92-4ef8-8c4a-5dbdaee8ad4d': mount: wrong fs type, bad option, bad superblock on /dev/md0, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so


      In the details section I found:

      The first error suggested to

      Source Code

      1. dmesg | tail
      which gave me the following output:

      After that error I deleted everything and created it again but the same error keeps coming up. I made sure that everything is ready before making the next step by waiting till the disk spun down.

      I suppose that the error is "Device sda/sdb is misaligned". How can I fix that?

      Best regards,

    • You are really making a linear raid array with two 5 TB drives? That is a lot of data to lose if one fails = lose all data.

      Maybe you did something before it finished formatting. I would try formatting from the command line. mkfs.ext4 /dev/md0

    • Thanks for your reply.
      I tried to create the filesystem from the command line (and no error while creating it) but it's still the same error. After that I also reinstalled OMV completly new but it didn't change anything.

      Linear Raid with 2x5TB is ok for now as I'm trying to get used to OMV and experiment with it before using it in production with important data.
    • You are using a BananaPi for production??

      Not sure why it isn't formatting correctly. Try wiping both disks and formatting them individually. You could use the unionfilesystem plugin to pool them.

    • Should not even carry one partition technically if you do a linear raid.

      Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.
