So, what is the better approach? Using LVM mirroring capabilities or putting the LVM on a mdadm RAID 1.
lvm require extra log partition for mirroring. Altough that log partition doesn't require much space but still a extra pain.
LVM on mdadm RAID1 is more stable than LVM's own mirroring at the moment.
You don't need to partition the disk and create a new PV just for theLVM mirror log. You can use "--alloc anywhere" while creating the mirrorvolume and LVM will gladly allocate mirror log on one of your mirror legs.
