Disk Expansion steps: VMS, Unity without LVM
===============================================
Slight changes to procedure for RHEL.
1. Display and verify LUN size.
# powermt display dev=all
# df -h /path/to/mount/point
# fdisk -lu /dev/emcpowerX1
2. Unmount volume.
# umount /path/to/mount/point
3. Check FS.
# fsck -n /dev/emcpowerX1
4. SDP to expand disk.
5. Verify new LUN size. If not detected, reboot.
# fdisk -lu /dev/emcpowerX
6. Remove journaling.
# tune2fs -O ^has_journal /dev/emcpowerX1
7. Resize partition. Delete then recreate partition with new size.
# fdisk /dev/emcpowerX
8. Check FS.
# e2fsck -f /dev/emcpowerX1
9. Resize FS.
# resize2fs /dev/emcpowerX1
10. Check FS.
# fsck -n /dev/emcpowerX1
10. Turn on journal.
# tune2fs -j /dev/emcpowerX1
11. Remount volume. Verify new size.
# mount /path/to/mount/point
# df -h /path/to/mount/point
=======================================
1. if baremetal run: /usr/bin/rescan-scsi-bus.sh to scan;
if OVM scan disk in UI;
if VM run commands below (if not automatically detected by server)
for BUS in /sys/class/scsi_host/host*/scan
do
echo "- - -" > ${BUS}
done
2. fdisk /dev/
3. pvcreate /dev/
4. vgextend /dev/
5. lvextend -l +100%FREE
6. resize2fs
7. lvdisplay
