Hi,
I have LV type raid1 and after adding couple disk to VG I anted to
change raid1 to raid5 so I did:
> # lvconvert --type raid5 /dev/first/lxc-owncloud-data-new
it converted LV to RAID5 but didn't add new spare so:
> # lvconvert --stripes 2 /dev/first/lxc-owncloud-data-new
After this LV have 3 device but I didn't saw any sync action and
movement on the disk so to resync data I used:
> # lvchange --resync /dev/first/lxc-owncloud-data-new
It was like conversion from 6 to 12TB so after 40 hours when resync
was done I do mount and XFS complain about FS.
What I did wrong?
Is there a chance that I can recover data?
