[linux-lvm] domino on lvm2+reiserfs




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.
