Re: [linux-lvm] vg recovery after PV failure

Eamonn,

in case "a bit odd" means a HW flaw, you need to vgcfgrestore the LVM metadata
back onto a sane device. You can even "vgcfgrestore -i" to a disk with
different size, bacause you loose the data on the old flaky disk anyway
(assuming it is completely inaccessable) :-(

If your friend had all LVs striped onto both PVs, data is lost anyway.

Hint: backups are your friends friends.
