Error Messages Observed

These messages appear in dmesg after an unsuccessful activation of a volume groups logical volumes.

device-mapper: table: <major>:<minor>: <block device> too small for target: start=<sector>, len=<sector>, dev_size=<size>

kernel: EXT4-fs (dm-9): bad geometry: block count <number> exceeds size of device (<number> blocks)

Fix Procedure

1. Deactivate the volume group's logical volumes.
   1. # vgchange -an <volume group>
2. Rescan all SCSI Host Adapters.
   1. # echo '- - -' > /sys/class/scsi_host/<host#>/scan
3. Rescan all SCSI block devices associated with the volume group.
   1. # echo 1 > /sys/block/<block device>/device/rescan
4. Resize all physical volumes associated with the volume group.
   1. # pvscan
   2. # pvresize /dev/<block device>
5. Activate the volume group's logical volumes.
