HELP! OS usb drive went read-only during upgrade to 5.x from 4

  • I tried upgrading my OMV NAS to version 5 and the box never came back up after the first reboot. It appears the system drive (a 32gb flash drive) went read-only.
    After much trial and error, I decided to do a fresh install on a new disk and recover the system. The new disk, running OMV 5, immediately recognized the RAID 5 array, but no filesystem.

    How do I recover my files?

  • # cat /etc/mdadm/mdadm.conf

    # mdadm.conf

    #

    # !NB! Run update-initramfs -u after updating this file.

    # !NB! This will ensure that initramfs has an uptodate copy.

    #

    # Please refer to mdadm.conf(5) for information about this file.

    #


    # by default (built-in), scan all partitions (/proc/partitions) and all

    # containers for MD superblocks. alternatively, specify devices to scan, using

    # wildcards if desired.

    #DEVICE partitions containers


    # automatically tag new arrays as belonging to the local system

    HOMEHOST <system>


    # instruct the monitoring daemon where to send mail alerts

    MAILADDR root


    # definitions of existing MD arrays

  • I think that is a bad sign.. (not sure how that could have happened)...

    I would agree as I read this yesterday, the output from #3 is not good, there is also no information re hardware or how the upgrade was done, we've gone from a clean install recognising the array to mdadm saying there's nothing there.

    Raid is not a backup! Would you go skydiving without a parachute?

    I was wondering if maybe he did the reinstall w/ the storage drives connected... and maybe overwrote something on one of the drives? Hopefully he doesn't learn the hard way how accurate your signature is
