Hi All
Exporting cephfs with the CEPH_FSAL
I set the following on a dir:
setfattr -n ceph.quota.max_bytes -v 100000000 /dir
setfattr -n ceph.quota.max_files -v 10 /dir
>From an NFSv4 client, the quota.max_bytes appears to be completely ignored,
I can go GBs over the quota in the dir. The *quota.max_files* DOES work
however, if I try and create more than 10 files, I'll get "Error opening
file 'dir/new file': Disk quota exceeded" as expected.
>From a fuse-mount on the same server that is running nfs-ganesha, I've
confirmed ceph.quota.max_bytes is enforcing the quota, I'm unable to copy
more than 100MB into the dir.
According to [1] and [2] this should work.
Cluster is Luminous 12.2.10
Package versions on nfs-ganesha server:

My ceph.conf client section:
