[Gluster-users] Gluster 3.10.5: used disk size reported by quota and du mismatch
Hi, There was a accounting issue in your setup. The directory ans004/ftp/CMCC-CM2-VHR4-CTR/atm/hist and ans004/ftp/CMCC-CM2-VHR4 had wrong size value on them. To fix it, you will have to set dirty xattr (an internal gluster xattr) on these directories which will mark it for calculating the values again for the directory. And then do a du on the mount after setting the xattrs. This will do a stat that will calculate and update the right values. To set dirty xattr: setfattr -n trusted.glusterfs.quota.dirty -v 0x3100 <path to the directory> This has to be done for both the directories one after the other on each brick. Once done for all the bricks issue the du command.

[Gluster-users] Gluster 3.10.5: used disk size reported by quota and du mismatch
Hi Hari, Hi Sanoj,
thank you very much for your patience and your support!
The problem has been solved following your instructions :-)
N.B.: in order to reduce the running time, I executed the ?du? command as
follows:
for i in {1..12}
do
du /gluster/mnt$i/brick/CSP/ans004/ftp
done
and not on each brick at "/gluster/mnt$i/brick" tree level.
I hope it was a correct idea :-)
Thank you again for helping me to solve this issue.
Have a good day.
Mauro
