RE: [Xen-users] Im Resize

["David Morris" <david.morris@xxxxxxxxxx>]

The method will vary depending on how your file systems are stored, what OS is 
represented in the file systems, etc. In my case, my data is stored in LVM 
'devices'... here is the outline
my expert provided of the steps:

  1) reduce the size of the filesystem (resize2fs or parted) (see also qtparted)
  2) reduce the size of the lvm using lvreduce (or lvresize)
  3) reduce the size of the physical volume using pvreduce
  4) reduce the size of the raid array using 'mdadm grow -z somesize'
  5) reduce the physical partition size using fdisk (or similar)

Step 1 will have to be repeated for EACH file system. If the devices contain
partitions, then you'll need to apply fdisk et al to each partitioned device 
and may
need to move partition data in that process ... in my example, the LVM space 
was the
last partition.

If your devices are all standard Linux file systems, and you aren't using HVM 
(e.g., don't need to worry about MBRs), your easiest approach may be to mount 
and tar/gzip each partition. Resize it and then put the data back.
