[Xen-users] expanding Xen guest disk size
In my previous post I adviced to delete the partition containing
volumegroup and a logical volume and recreate this partition to extend
it's size.
I forgot to mention some additional required steps.
After the hard work on the partitions you will have to alter your LVM
structure with it's physical volume (PV), volume group (VG) and logical
volume (LV).
Use parted or fdisk to:
- Delete partition 2 (hda2)
- Delete partition 1 (hda1)
- Create partition 1 Start (1) End (13) type 83 set active
- Create partition 2 Start (14) End (-1) type 8e
Extend your LVM layout:
- Resize the PV =>man pvresize
- Extend the VG => man vgextend
- Resize the LV => man lvresize
Resize your filesystems:
- resize2fs or xfs_growfs
Here the disklayout inside domu from Sylvan's last post in this thread:
root@testserver ~]# fdisk -l
Disk /dev/hda: 15.7 GB, 15728640000 bytes
255 heads, 63 sectors/track, 1912 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/hda1 * 1 13 104391 83 Linux
/dev/hda2 14 764 6032407+ 8e Linux LVM

root@testserver ~]# df -m
