I've just inherited a box that has a single / volume plus a swap. I'd
really rather have /home seperated. LVM is still new to me so i'd like
someone else's opinion on the steps i've managed to come up with.
I'd like to reduce the single 75G vol to 20G, then create a /home vol
with the remainder.
[bally@apollo ~]$ lvdisplay
--- Logical volume ---
LV Name /dev/VolGroup00/LogVol00
VG Name VolGroup00
LV UUID us9s35-kxoF-1L92-0zsZ-vJtj-lO7A-Q89zmE
LV Write Access read/write
LV Status available
# open 1
LV Size 75.25 GB

--- Logical volume ---
LV Name /dev/VolGroup00/LogVol01
VG Name VolGroup00
LV UUID roe2Xm-PbHg-5HwP-5klc-SGRr-65Lx-jSpjuW
LV Write Access read/write

# open 1

So, the steps i have so far:
boot rescue mode
# tune2fs -O ^has_journal /dev/hda # discontinue journaling
# lvm
lvm > vgscan
lvm > vgchange --available y VolGroup00
lvm > exit
e2fsck -f /dev/VolGroup00/LogVol00 # check & repair
resize2fs -p /dev/VolGroup00/LogVol00 20G # resize to 20G
e2fsck -f /dev/VolGroup00/LogVol00 # check & repair
# lvm
lvm > lvreduce -L20G /dev/VolGroup00/LogVol00
lvm > lvcreate -L55.25G -nhome # create volume for /home
lvm > exit
e2fsck -f /dev/VolGroup00/LogVol00 # check & repair
e2fsck -f /dev/VolGroup00/home # check & repair
# tune2fs -O +has_journal /dev/hda # restore journaling
Does this look OK? And is using tune2fs strictly necessary here?
Am I heading for a re-install?
