you have 'set' the size to 229.99G
-L 229.99G
you want to 'increase' by 229.99G
-L +229.99G

Greetings gurus:
I do not deal with LVM on a daily basis, and I think my note-taking of
previous LVM commands needs to be polished.
== Background ==
Have a VM with 2 virtual disks, 30G (LVM only on 3rd partition) and 65G
(all LVM) respectively.
A single VG on the server: VolGroup00; four LV's: LogVol00 to 03
== Problem ==
The 71G /usr/local (VolGroup00-LogVol02) hit 100%
I shut the server down and increased the 65G virtual disk up to 295G
(+230G) -- the thought process: take /usr/local from 71G to ~300G.
Booted into single and fdisk'ed a new /dev/sdb2
/dev/sda3 4298 30720 27057152 8e Linux LVM
/dev/sdb1 1 8485 68155731 83 Linux
/dev/sdb2 8486 38509 241167780 83 Linux
Consulted my notes and did the following:
pvcreate /dev/sdb2
umount -vv /usr/local
vgextend VolGroup00 /dev/sdb2
lvextend -L 229.99G /dev/mapper/VolGroup00-LogVol02
e2fsck -f /dev/mapper/VolGroup00-LogVol02
resize2fs /dev/mapper/VolGroup00-LogVol02
mount -vv /usr/local
df -h
/dev/mapper/VolGroup00-LogVol02 227G 68G 148G 32% /usr/local
My confusion came in when I saw 227G total and not 300G.
My suspicion was confirmed with pvdisplay -s (and pvs)
Device "/dev/sda3" has a capacity of 0
Device "/dev/sdb1" has a capacity of 0
Device "/dev/sdb2" has a capacity of 71.83 GiB
But I am confused even further; I thought pvdisplay was referring to the
physical disks, but fdisk does not show a missing 71G for /dev/sdb2
pvs
PV VG Fmt Attr PSize PFree
/dev/sda3 VolGroup00 lvm2 a-- 25.80g 0
/dev/sdb1 VolGroup00 lvm2 a-- 65.00g 0
/dev/sdb2 VolGroup00 lvm2 a-- 229.99g 71.83g
vgs
VG #PV #LV #SN Attr VSize VFree
VolGroup00 3 4 0 wz--n- 320.79g 71.83g
== Questions ==
Where did I go wrong, or did I go wrong?
It obviously seems like I am missing 71G, but am I missing it and how do I
go about reclaiming it?
