Centos Xen resizing DomU partition and volume group
- by thepearson
I have a setup like so:
Dom0 LV
|
DomU Physical Disk
| |
XVDA1 XVDA2
(/boot) (DomU PV)
|
VolGroup00
(DomU VG)
| |
LogVol00 LogVol01
(swap) (/)
I am trying to resize the DomU root Filesystem. (VolGroup00-LogVol01) I realize that I now need to resize the partition XVDA2, however when I try doing this with parted on Dom0 it just tells me "Error: Could not detect file system."
So to resize the root part VolGroup-LogVol00 shouldn't the process be:
# Shut down DomU
xm shutdown domU
#Resize Dom0 Logical volume
lvextend -L+2G /dev/volumes/domU-vol
# Parted
parted /dev/volumes/domU-vol
# Resize root partition
resize 2 START END
(This is where I get an error) "Error: Could not detect file system."
# add the vm volume group to Dom0 lvm
kpartx -a /dev/volumes/domU-vol
# resize the domU PV
pvresize /dev/mapper/domU-pl (as listed in pvdisplay)
# The domU volume group should automatically adjust
# resize the DomU lv
lvextend -L+2G /dev/VolGroup/LogVol00
And then obviously increase the fs, remove the device from kpartx etc
The problem is I dont know how to resize the partition? How do I resize this partition so I can run pvresize on the DomU?
Thanks
