Hi,
I am running Centos 7 and have created a virtual block device with
ZFS (ZVOL). I put XFS onto the block device without partitioning it.
This worked very well as storage disk for a VM.
A few days ago I wanted to increase the size of the block device,
but accidently decreased it by 1 TB (from 7 to 6). I found out about
it and immediately increased the size of the drive to 8 TB
afterward.
The XFS partition can still be mounted and I can list the files on
it, but xfs_repair -n says: "Sorry, could
not find valid secondary superblock"
Is there the possibility to rescue some files?
kind regards
Markus
