Mirroring with lvm2
I've got a new machine with two 750G drives. I did a fresh install of F12 using the default disk layout on one of the drives. Now I'm trying to mirror the drive. I've figured out how to mirror /boot with mdadm. Now I'm trying to mirror the main filesystem using lvm. I think I have most of it figured out but when I try to use the lvconvert command to mirror the volume I get an error about there not being enough available extents!! The drives are practically empty!! I found the option to using ram for the mirror logs but remirroring after every reboot isn't acceptable.
Has anyone figured out how to do the mirroring with lvm?
