Thanks Karl and Marcin, I hadn't realised software RAID worked on a
per partition basis. I'm looking into it now.
If mirroring on LVM is stable though, it might still be preferrable as
then I only have to use one set of tools instead of two --- can anyone
comment on how stable they've found mirroring under LVM.
Also does the fact that software RAID doesn't use a disk log mean that
LVM is actually better/faster than RAID at correctly recovering from
crashes that leave the mirrored disks out of sync?

Were you able to specify which PV the log was created on?
Thanks,
Jess
