i can confirm ... as you told, its working the "top" level accepts the quota vm-prod-fsusr-01:~# scripts/ceph_quota_report.sh Directory Used Quota Percent -------------------------------------------------------------------------------- users 3.8GiB 1.2GiB 333% users/1 0B 1.1GiB 0% users/1/2 0B 954MiB 0% users/1/2/3 0B unlimited N/A users/1/2/3/4 0B unlimited N/A but my samba mounts: //sambasrv/1 1.2G 1.2G 0 100% /mnt3 //sambasrv/users/1 1.2G 1.2G 0 100% /mnt2 //sambasrv/users/1/2 1.2G 1.2G 0 100% /mnt i dont know, how i can set different quota in one directories subdirectory like: data/users/user1 10g data/users/user2 5g data/users/user3 20g data/users/user4 10g regards, ronny Am 2026-03-16 12:44, schrieb Chris Palmer via ceph-users:
Hi Ronny
I use the very straightforward method of having a linux VM that kernel-mounts the cephfs filesystem via fstab at /mnt/cephfs. I apply an 8TB quota to one of the top-level directories /mnt/cephfs/data2 (not the root of /mnt/cephfs as I mistakenly said earlier!). Samba then exports /mnt/cephfs/data2/x, /mnt/cephfs/data2/y etc just via the VM's directory tree. Each of the exports (some with different access permissions etc specified in samba) all correctly share the quota set on data2.
This is a low-usage cluster, especially via samba, and has always just worked. So I've never had any reason to experiment with vfs etc.
Regards, Chris

hi chris and thanks for answer.
do you use samba vfs ceph/ceph_new or mount cephfs on samba server and export that? what do you mean, "cephfs root though"
i would like to have something like that
data/users/user1 10g data/users/user2 5g data/users/user3 20g data/users/user4 10g data/share1 100g data/share2 200g ...

I do use cephfs exported via samba. My quota is simply done at the cephfs root though. That works fine with Win10 & Win11 hosts - they see the correct total/used/available space. I haven't tried multiple quotas or setting further down the tree though.

hi, hope you can help me.
i like to export an cephfs via samba an ctdb. its all working fine via kernel cephfs client.
i set now quota to the users home dir. quota also working fine.
but now, the problem ... on the client machine, i do not see the quota space. mostly, i see the complete cluster, or on windows i see nothing about disk usage.
it would be important for us and the user, to se the remaining space.
samba vfs ceph and ceph_new would not work ... i always got: cephmount_mount_fs: [CEPH] mount failed: user_id='XXX' fsname='XXX' No such file or directorymake_connection_snum: SMB_VFS_CONNECT for service 'XXX' at 'PATH' failed: No such file or directory
does anybody use cephfs with samba an quota? running out of ideas, so an help is welcome.
regards, ronny
