I was looking into snapshots using the doc below to try and see if delta copies with rsync matched data better if I take a snapshot of a file system, mount it and rsync transfer the data. Right now, dumps don't seem to match much data due to changes in the sequences and a very active mail cache pgsql db.
http://people.freebsd.org/~rse/snapshot/ I created the snapshot and got it mounted, took a minute or so for each to do this on my /usr ufs file system on FreeBSD 6.2 with 2GB RAM, dual P4 procs with SMP and RAID 5 (I know, will be changing soon) SATA150 drives. In the midst of doing this, the currently running pgsql db, remember I said it was very active amavisd-maia supporting two mail gateways as a mail cache if you know Maia Mailguard, I started getting these messages and things stopped responding well... Sep 24 16:59:02 mx1 kernel: aac0: COMMAND 0xc6530fc0 TIMEOUT AFTER 38 SECONDS Did a reboot, it tooks several minutes to start reboot after the command. I even got some of these kernel messages after the reboot, not until I rm -f the snapshot file did it stop. I am wondering how I need to handle snapshots when trying this, especially if included in a routine backup script? I haven't made it to the solution part of the above doc yet, wanted to check here before I try anything again. Also, haven't tested my rsync until tonight to see if the file system transfer will make a difference in my ability to match data better. But I'd still like use the snapshot as a backup solution. -- Robert _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
