Mauelshagen @ 2002-10-31 11:54 UTC (permalink / raw) To: linux-lvm You mentioned that you were dd'ing stuff of the partially failed drive. If you get a replacement drive of the same size, dd everything onto it, "pvcreate -ff ..." it and vgcfgrestore LVM's metadata onto it. "vgscan;vgchange -ay" afterwards should bring your VG back to life but you will loose some of your data. As already said by Jon: you want to go RAID1/5.

If so, i'd suggest you start looking for a new boss, one that gives you enough money to at least run software raid. Ask him how much a complete data loss costs ? Not just your salary for the time you try to recover, but also his time, and the rest of the workers while the system is down because he saved money on disk space. And dont get me started about backup. Remober, if you DO go raid, you NEED to know when a disk goes down, because if not, you might as well not run raid at all. This means some sort of management software that keeps an eye on the disks, and emails you when one fails. Hotswap _MIGHT_ not be needed, but it is nice.
