Ceph » CephFS

When there's mixed quota values on a filesystem, incorrect values are shown

For example take a dir tree as follows (filesystem mounted on /mnt/mycephfs):

/mnt/mycephfs/dir1
/mnt/mycephfs/dir1/dir2

Set the mixed quotas
setfattr -n ceph.quota.max_bytes -v 30G /mnt/mycephfs/dir1
setfattr -n ceph.quota.max_files -v 10000 /mnt/mycephfs/dir1/dir2

then consider these calls

df -h /mnt/mycephfs
Filesystem Size Used Avail Use% Mounted on
ceph-fuse 99G 0 99G 0% /mnt/mycephfs
df -h /mnt/mycephfs/dir1
Filesystem Size Used Avail Use% Mounted on
ceph-fuse 30G 0 30G 0% /mnt/mycephfs
df -h /mnt/mycephfs/dir1/dir2/
Filesystem Size Used Avail Use% Mounted on
ceph-fuse 99G 0 99G 0% /mnt/mycephfs

When the last df is ran, we should see 30G size and not filesystem size.
