Package: nfs-kernel-server
Version: 1:1.3.4-2.5
Severity: normal
Dear Maintainer,
We use NFSv3 to mount /home on our lab machines. The mount is a ZFS
filesystem with snapshot visibility enabled (this makes
/home/.zfs/snapshot be visibile to users so that they can restore files
if needed). We are using standard /etc/exports, and the ZFS sharenfs
option is disabled.
Since the upgrade to Buster from Stretch, we are unable to view the
contents of snapshots under .zfs/snapshot/<snapshot_name>, but can
accurately see the list of snapshots in .zfs/snapshot. Each ZFS snapshot
is a separate file system, mounted under the snapshot name in
.zfs/snapshot. The nohide option has no effect on whether we can see them
or not.
The /etc/exports below is a snippet of the file, but represents the
base case where we are encountering this issue. I am not sure if it is a
bug in NFS, ZFS or a user issue.
Thanks
Kyle
