I hope this is the right way to post the output.
Would appreciate any ideas how to find out which files are broken.
kind regards,

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.
If that was a normal LVM block device, there would have been no
trouble. But you're using something special, unusual and completely
untested, so the most likely outcome is going to be that you still
have a pile of broken bits.
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"
Full output, please, as well as the version of xfs_repair you are
using...

Cheers,
