Kernel Panic at boot when PV missing from VG (LVM)
I installed a server with Centos 5.2 on a machine with two physical sata-harddisks.
I used LVM to create a mirror for the two LVs, the root-LV plus one data-LV. (with lvcreate/lvconvert). I only have two disks so I used ócorelog.
For testing reasons I simulated the failure of one harddisk and shutdown and removed /dev/sda (with /boot on it).
I created a boot-CD with mkbootdisk before. The boot-CD does not start the system but brings a kernel-panic because one PV is missing.
I don't have a clue how to remove the failed PV from a system which cannot boot.
Of course I already googled a lot for this problem but did not find a proper solution.
Did I miss a detail? Is mirroring of LVs with LVM (with corelog) a usable solution for harddisk-failures?
