Hi all,

I'm using amanda 2.4.5 (RPM package from Fedora Core 4).

I've got amanda running for a few months now, and am ready to move all
hosts from the old backup server (BackupExec) to the server running
amanda. On a few servers we used to work with LVM snapshot volumes to
backup our data. When we configure amanda to backup a snapshot volume
using gnutar, we seem to have a problem with the planner timing out on
the estimate.

The planner needs the estimate in order to make a solid decision on
which disk to backup when and what level of backup is needed. All the
other backups run fine, but whenever I want to backup a snapshot
volume created with LVM2, I get a long timeout which eventually times
out...

Is it realy LVM2 that is the source of the problem?  I see no
difference at all in my hosts that use LVM2 snapshots.
Or is it just gnutar, doing stat()s on a lot of small files.

Someone any idea's?

As workaround, you may switch to the faster "calcsize" method of
estimates, see:
