[Gluster-users] Gluster 3.10.5: used disk size reported by quota and du mismatch

[Sanoj Unnikrishnan]

Hi Mauro,

This may be an issue with update of backend xattrs.
To RCA further and provide resolution could you provide me with the logs by
running the following fsck script.
https://review.gluster.org/#/c/19179/6/extras/quota/quota_fsck.py

Try running the script and revert with the logs generated.

Thanks,
Sanoj
