Re: vfs_ceph ignoring quotas

[Felix Stolte <f.stolte@xxxxxxxxxxxxx>]

That's bad news, but maybe there is a workarround. Samba offers the 
opportunity to define a custom df command. If I could extract the 
current utilization or size of a directory with a quota, i think i 
should be able to write a little df command. The quota is stored as an 
extended attribute, where can i get its utilization?

Regards Felix
