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

[Mauro Tridici]

Hi Sanoj,

could you provide me the command that I need in order to backup all quota limits?
If there is no solution for this kind of problem, I would like to try to follow your “backup” suggestion.

Do you think that I should contact gluster developers too?

Thank you very much.
Regards,
Mauro
