Hallo List, We are using LVM with SAN and multipathd. I try to setup mirroring with LVM. So I do pv create on a mpath device. vgcreate, add the pv to the vg, create a lv and setup a mirror with this: lvconvert -m1 vg<name>/lv<name> /dev/mapper/mpath0 --mirrorlog core My intention is to create a logical volume which can handle SAN Disk failure. But in this shown setup i get a error (unavailable logical volume) when one of the san LUNS is missing. Can this system work or did i need to setup a mdadm device before pvcreate ? Hope you can help me because Redhat can't... them sitting two weeks on this error / miss configuration without any solution...
