Yeah, I did some googling and it looks like I need to use something called LVM, I found the docs but I'm stuck
Heres my physical volumes
Code: Select all
[root@localhost ~]# pvdisplay
--- Physical volume ---
PV Name /dev/sda2
VG Name VolGroup00
PV Size 372.50 GB / not usable 0
Allocatable yes (but full)
PE Size (KByte) 32768
Total PE 11920
Free PE 0
Allocated PE 11920
PV UUID 1NQ7gW-Zk56-2C1v-Xvy1-Vhxw-ckXt-Y6kmoe
--- Physical volume ---
PV Name /dev/sdb1
VG Name VolGroup00
PV Size 372.59 GB / not usable 0
Allocatable yes
PE Size (KByte) 32768
Total PE 11923
Free PE 2
Allocated PE 11921
PV UUID VjnV3a-Bo1a-q3xw-ddyr-24hN-ey8F-50K6Va
--- Physical volume ---
PV Name /dev/sdc1
VG Name VolGroup00
PV Size 372.59 GB / not usable 0
Allocatable yes
PE Size (KByte) 32768

Free PE 11923

PV UUID qMP8Vy-sqN0-P6WL-Ck82-4Fl4-9yJi-92XD8C
But my third disk got added to the wrong logical volume it looks like
Code: Select all
[root@localhost ~]# lvdisplay
--- Logical volume ---
LV Name /dev/VolGroup00/LogVol00
VG Name VolGroup00
LV UUID 64tpc9-uVNH-qG9w-tf2p-jJjw-ZlaS-76PM0m
LV Write Access read/write
LV Status available
# open 1
LV Size 744.06 GB
Current LE 23810
Segments 2
Allocation inherit
Read ahead sectors 0
Block device 253:0
--- Logical volume ---
LV Name /dev/VolGroup00/LogVol01
VG Name VolGroup00
LV UUID 5DWUAN-1EFX-VqST-MV6w-Or2v-lHhs-hsXoW3
LV Write Access read/write

# open 1

Here's the documentation I've been going by
http://www.tldp.org/HOWTO/LVM-HOWTO/index.html
I was trying to
extend my volume
Code: Select all
[root@localhost ~]# lvextend -L+400G /dev/VolGroup00/LogVol00
Extending logical volume LogVol00 to 1.12 TB
Insufficient allocatable logical extents (35735) for logical volume LogVol00: 36610 required
It looks like it's trying to take it from somewhere other then my third drive, if anyone could shed a little light as to what I did / am doing wrong it'd be much appreciated.
EDIT Solved the issue thanks to
this very informative tutorial
Edit: Maybe not, I thought it was becase
Code: Select all
[root@localhost ~]# lvdisplay
--- Logical volume ---
LV Name /dev/VolGroup00/LogVol00
VG Name VolGroup00
LV UUID 64tpc9-uVNH-qG9w-tf2p-jJjw-ZlaS-76PM0m
LV Write Access read/write
LV Status available
# open 1
LV Size 1.09 TB
Current LE 35714
Segments 4
Allocation inherit
Read ahead sectors 0
Block device 253:0
but df -h shows a size of 721GB still
Triple edit: 4 hours of google turned up
