We are working on trying out some new HA and/or recovery techniques with SLES 11 SP3 and our new SVC hardware. One thing that I would like to try is setting up mirroring via the SVC of a LUN that has mysql data on it. This LUN is dedicated to a SLES 11 SP3 server on our z114, but it is also part of a logical volume. (Right now, its a 1 physical volume LVM.)
Setting up the mirroring is not a problem. My question is more related to recovery. I don't know a lot about how LVM works. How much about the volume is stored on the LUN itself and how much is stored elsewhere in the opsys filesystem? If we have a recovery server pointed to the mirrored volume, will it see the LVM metadata? Any hints/tips on mirroring LVM volumes? Or, should we stay away from LVM for anything we want to mirror?
