Hello. Just wanted to point out quickly, although it doesn't actually answer the question, linux software raid may be an option for you. Set both partitions to Linux raid, then use mdadm to create a RAID 1 accross the 2 partitions. I am currently running a similar setup, except I am using a raid5 across 4 partitions, with a raid1 and a raid10 earlier in the disk for OS, LVM on the raid5, and an additional VG containing a mix of striped, linear and mirrored volumes.

Hi all, I've been trying to find out about LVM mirroring, but it's hard to find much information in the documentation. Is mirroring considered stable/ready for production use yet? "man lvcreate" and "man lvconvert" suggest that the current stable versions support creating mirrored volumes, but the HOWTO has nothing to say about it. On a more detailed note, what sort of size does the physical volume for the disk log need to be in relation to the size of the logical volume to be mirrored, and is there any way to specify which physical volume will hold the disk log (either using lvconvert or lvcreate)? I've got a situation where I want to mirror only a partition of a physical disk on to that of another physical disk, not the whole disk; so software/hardware RAID isn't an option.
