Good afternoon,
I am wondering if anyone out there has had success with the vfs_ceph_snapshots
module for exposing CephFS snaps as shadowcopy on samba shares?
As of current we?ve been trying with both Ubuntu 20.04 (samba version 4.13.17)
and Rocky Linux (samba version 4.15.5), and are seeing completely different
results on both.
On the Ubuntu machines when connecting to the samba share via a client there is
absolutely no snapshots showing up via shadowcopy,
On the Rocky Linux machines when connecting to the samba share via a client the
snapshots do actually appear, however when trying to restore nothing occurs, and
when opening the snapshot to view it is completely empty.
As a workaround we?ve actually been able to use the traditional vfs_shadow_copy2
which works fine, but it would be nice to make use of the tool designed
specifically for CephFS ?
I?ve attached the share definitions for both Ubuntu 20.04 and Rocky Linux below:
Ubuntu 20.04
[share2]
guest ok = Yes
path = /mnt/cephfs/share2
read only = No
vfs objects = ceph_snapshots
Rocky Linux
[share2]
guest ok = Yes
path = /mnt/cephfs/share2
read only = No
vfs objects = ceph_snapshots
Setting the log level to 5 for vfs we?ve been able to capture these outputs from
both machines when checking the snapshots from a client
