Testdisk finds partition but OMV (Debian) does not recognize it
Posted: 25 Nov 2018, 11:23
Hi all,
I have a NAS at home equipped with openmediavault.
Yesterday, I upgraded from version 3 to version 4. Everything went well except that it seems to have corrupted the 3TB datadrive.
If I boot into gparted live, the disk shows up as a 3TB zfs drive (it's formatted as ext4).
Testdisk (running in Linux, as root) can see the partition no problem, and can copy files from it as well.
However, if I tell Testdisk to write the new partition structure, and reboot, nothing changes. Again, Debian and gparted cannot read the filesystem but Testdisk sees everything just fine.
If I connect the disk to my Windows PC, it gives the error that the disk needs to be formatted. If I run Testdisk in Windows, it only shows a 800gb partition (that should be roughly the free space available).
Any thing I can do to make the partition work as before? Or is my only option to copy all files to a new disk?
Thanks a lot for your help!
Hans
