Description Anoop C S 2025-03-04 06:56:39 UTC 
When vfs_ceph_snapshots is used with vfs_ceph, snapshot contents residing under any level beyond the share root are not listed as previous versions. See below for configuration used:

[cephfs-subvol-new]
	comment = For samba share of subvolume subvol
	path = /volumes/_nogroup/subvol/d2916e6d-a054-41f1-ac77-17ee77f22365
	read only = No
	vfs objects = ceph_snapshots ceph_new
	ceph_new:config_file = /etc/ceph/ceph.conf
	ceph_new:user_id = foo
	ceph_new:filesystem = cephvol

Sample snapshots available within the file system:
$ smbclient \\\\192.168.122.101\\cephfs-subvol-new -U root%smb -c "cd .snap;ls"
