After the excellent presentation on LVM by Brian at PLUG earlier this month, and after our recent disk failure/recovery this week, I was working on reorganizing our PVs. I had created a new pv on a new RAID1 array (md5) and was loving the idea of moving the logical volumes over from (md4, on a single-disk degraded RAID1 array) to the new array, with pvmove. So, I made some backups of files using rsync, and this morning after that had finished, I fired off:
# pvmove -v -i10 /dev/md4 And it commenced to, I presume, do the right thing. After about 17%, I got some messages (which regrettable I did not preserve) about suspending (??) the pvmove, and my connection to the machine froze (done remotely over the network, no console available). A few hours later, I got down to the colo and looked at the console. There was a login prompt, which I could type at, but I never got a password prompt. So, I rebooted and it came back up fine, but the pvmove had clearly not succeeded. Googling about, I found this, which looks like what I saw: http://www.novell.com/support/kb/doc.php?id=7004393 In brief, it suggests that you don't do a pvmove affecting a logical volume that holds /var and/or /var/run. Ouch, and: WHY-IS-THIS-NOT-IN-A-MUCH-LARGER-FONT??? Has anybody else run into this? -- Russell Senior, President russ...@personaltelco.net _______________________________________________ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug
