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

[Mauro Tridici]

Dear Sanoj,

thank you very much for your support.
I just downloaded and executed the script you suggested.

This is the full command I executed:

./quota_fsck_new.py --full-logs --sub-dir /tier2/CSP/ans004/ /gluster

In attachment, you can find the logs generated by the script.
What can I do now?

Thank you very much for your patience.
Mauro
