| cat /path/to/dir | grep rbytes | awk {'print $2'} assuming cephfs mount has dirstat option.
Here is the script I used in my environment:
#!/bin/sh
if [ -f "$1/.quota" ]; then
TOTAL=`cat $1/.quota`
USED=`cat $1 | grep rbytes | awk {'print $2'}`
USED=$((USED/1000))
echo $TOTAL $((TOTAL-USED))
else
df -k $1 | tail -1 | awk {'print $2,$4'}
fi
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 FelixOn 10/09/2018 10:59 AM, John Spray wrote:On Tue, Oct 9, 2018 at 9:14 AM Felix Stolte <f.stolte@xxxxxxxxxxxxx> wrote:
Hi folks,
i'm running a luminous cluster on Ubuntu 18.04 an want to share folders
on cephfs with samba using the vfs_ceph. Sharing works fine, but the
quotas I set on the directories is ignored and every share reports its
size as the total size of the cephfs. Anyone got this working? Or is the
vfs lacking quota support?
Looks like the Samba VFS is always mounting CephFS at the root[1],
including if you're exporting a subdir (nfs ganesha used to be this
way too) -- CephFS can only do the "magic" quota-based statfs if it
knows it's mounting a particular subdir.
