So there's an LVM volume consisting of 3 disks that was created
by the Debian Installer. One of the disks develops problems
(offline uncorrectable sectors) so I buy a fourth, the same size
exactly. Now, I pvcreate /dev/sde, and I vgextend bigstore /dev/sde,
and I try to pvmove /dev/sdb1. Doesn't work.
Somehow, creating and adding a disk manually gives 1 PE less:
PV Name /dev/sdb1
VG Name bigstore
PV Size 3000592939.52 kB / not usable 440.83 kB
Allocatable yes (but full)
PE Size 4194.30 kB
Total PE 715397
....
PV Name /dev/sde
VG Name bigstore
PV Size 3000590369.28 kB / not usable 2064.90 kB
Allocatable yes
PE Size 4194.30 kB
Total PE 715396
Once again, the disks are as similar as can be. Here's the relevant
part of /proc/partitions:
8 16 2930266584 sdb
8 17 2930266542 sdb1
8 64 2930266584 sde
Is there a way to safely reclaim my lost PE?
