Hello,
I have one LV (/home/hom_vg/home_lv) spanning over two PV. The PVs
were created on /dev/hdc1 and /dev/hdd1, both covering the entire
disks hdc (120 gb) and hdd (200 gb) respectively.
The mapping is linear.
My hdc is physically damaged... I could not even run fsck, badblocks
and dd_rescue. All of them give an output like this (from dmesg):
hdc: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hdc: dma_intr: error=0x40 { UncorrectableError }, LBAsect=512, high=0,
