CephFS snapshots with samba shadowcopy

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi All,

 

Curious if anyone is making use of samba shadowcopy with CephFS snapshots
using the vfs object ceph_snapshots?

 

I've had wildly different results on an Ubuntu 20.04 LTS samba server where
the snaps just do not appear at all within shadowcopy, and a Rocky Linux
samba server where the snaps do appear within shadowcopy but when opening
them they contain absolutely no files at all.

 

Both the Ubuntu and Rocky samba server are sharing out kernel cephfs mount
via samba, ceph version is 17.2.1 and samba version is 4.13.7 for Ubuntu
20.04 and 4.15.5 for Rocky Linux. 

 

I have also tried using a samba fuse mount with vfs_ceph with the same
results.

 

More so just curious to see if anyone on the list has had success with
making use of the ceph_snapshots vfs object and if they can share how it has
worked for them.

 

Included below is the share config for both Ubuntu and Rocky if anyone is
curious:

 

Ubuntu 20.04 LTS

 

[public]

        force group = nogroup

        force user = nobody

        guest ok = Yes

        path = /mnt/cephfs/public

        read only = No

        vfs objects = ceph_snapshots

 

Rocky Linux

 

[public]

        force group = nogroup

        force user = nobody

        guest ok = Yes

        path = /mnt/cephfs/public

        read only = No

        vfs objects = ceph_snapshots

 

Regards,

 

Bailey
