[linux-lvm] domino on lvm2+reiserfs

[CHicklin teamhuber com]

Hi,
        I'm
having some problems with a Lotus Domino server (v6.5.1) running on Suse
Linux Pro 9.1 (sorry, not RedHat, but I hope someone here can help anyway).
 
        The
OS is installed on the first and only SCSI hard disk on Channel A of a
dual-channel SCSI controller.  Channel B contains 4 SCSI hard disks,
each of which is a PV and are all part of the "datavg" volume
group.  There is one LV in datavg, namely lotuslv.  It has a
reiserfs filesystem on it which contains the Domino data directory.
        After
installing Domino, everything seemed to be running fine.  I even created
and destroyed a couple of snapshot LV's to test my backup scripts.  I
left the server running overnight, only to have it lock up.  I think
it may have to do with the snapshot LV's, but it did the same thing the
following day without taking a snapshot.  I've attached what I think
is the appropriate messages from the error log on the machine.
        Can
anyone take a look and see if there is an obvious problem here?  Are
there specific things to look out for when creating snapshots?  Any
issues with ReiserFS?  Thanks.
