Q: Plug OMV formatted HDD (EXT4) to my linux desktop and unable to access it via USB. Why?

  • Q: If I plug my OMV formatted HDD (EXT4) to my Linux (Mint 19.1) desktop using USB to SSD cable I am unable to access it. I don't even see the file system. What am I missing?


    OMV v4.1.3
    Odroid HC2


    Thanks in advance!

  • Is the USB/SSD cable device recognized my Mint? Look at the tail of dmesg after plugging it in to see.

    OMV AMD64 5.x on Chenbro NR12000 1U 1x 8m Quad Core E3-1220 3.1GHz 16GB ECC RAM.

  • Ok been a while but finally getting back to this... ran the dmesg (see attached text file) and it is seeing the drive. Going to wipe HDD and try again.

  • I'm not crazy. You can't format a HDD in EXT4 in OMV and try to read it on another Linux Mint via a HDD USB adapter and partition does not exist (see pic). I have also tried formatting the HDD as EXT4 and NTFS using Gparted then move it to OMV and unable to mount it. Can someone confirm this?

  • Been months and no replies. I can't believe I'm the only one having this issue. So what do you do if your HC2 dies? I guess I'm better off using Ubuntu instead of OMV.

  • Thanks. Darn, same issues with Ubuntu Mate 18 on the HC2! ;( I got some feed back from the Linux admin at work and mention that is probably LVM and to use fstab command. Will test.

  • Hi,


    AFAIK some SATA to USB adapters/docks mask the geometry of the drive, causing what I believe you are experiencing:


    - A drive formatted without the adapter appears as unformatted when connected to it.


    - A drive formatted when connected to the adapter is not recognized by the computer when attached directly to it (or behaves weirdly at most).



    I would suggest you connect the drive to an internal SATA port and see if that makes any difference.


    Hope this helps a bit.
