That's what I wanted to see,

For the disklist:
 finsen  /export/home-A /export/home

Try the attached patch.

It create one snapshot for each DLE.

Yes, however I'm afraid that if it creates a single disklist
for a glob, for instance /export/home/a*, creates snapshot /export/home
which I think would be acceptable.

But 'attempts' to create the same snapshot for glob /export/home/b*
and /export/home/c* those # zfs create snapshots will fail, which
may not actually be a problem.

However, when any of those globs completes and attempts to remove
the snapshot -- what will happen to the remaining dumps. They will
all lose their snapshots! (I think.)

I was hoping to have a snapshot for each of the directories within
the glob /export/home/a* which will work (on my system) since each
of the user directories is itself a mount point.

I recognize that there is no way to snapshot all of the As and then
all of the Bs.

I don't think there is a mechanism to maintain 'the' snapshot
until all of the globs complete. There is no cross-glob coordination.

Can you post the disklist file so I can interpret the debug file correctly.

The disklist posted differs only in that for the -A glob we ran with
zfs-snapshot rather than user-tar.

                                                thank you,

Brian,

What is the path of the snapshot, post the Amzfs_snapshot.20091019*.debug files.

Jean-Louis,

I reconfigured one of my globs to use dumptype zfs-snapshot
rather than user-tar. Backups ran well but I believe that we
did a single snapshot of /export/home rather than a snapshot
of /export/home/a* for each of the 'a' directories.

I think this because when I look on the client system in the
/tmp/amanda/client directory, at the Amzfs_snapshot.20091019*.debug
files I see sepatate zfs snapshots for things like /export/samba/<shares>
but only the single snapshot for /export/home and not unique snapshots

for

[finsen/tmp/amanda/client] cd /export/home
[finsen/export/home] ls -ld a*
drwxr-xr-x   2 agaupel  users          4 Aug 25 09:46 agaupel
drwxr-xr-x   2 along    users          4 Sep 11 13:37 along

While this may work fine for a limited number of a* directories
I'm afraid of what will happen if I again try to produce a
snapshot for the b* directories.

It may be that the snapshot create fails after the first successfull
attempt, but what happens when the first glob completes dumping and
attempts to remove the snapshot ?

I will revert that glob to user-tar dumptype for the time being.

                                                thank you,

                                                Brian
