Re: [Xen-users] Is XVD live resize possible?

Hi!
Say I export an LVM logical volume from dom0 as /dev/xvda to the domU:
disk = [ 'phy:xenimages/stan,xvda,w' ]
No I can lvresize xenimages/stan in dom0, but the domU stays ignorant
of this change.  How could I propagate the resize to the domU without
rebooting or temporarily breaking its connection to /dev/xvda?  Sort
of a SCSI rescan, perhaps?
   
 You have to resize the *file system* on the partition. Whether you can 
use a 'rescue CD' inside the virtualized environment, to resize your 
partitions, is an interesting question and may depend on your installed 
OS quite a bit. You can certainly resize non-'/' partitions from the 
live OS, and use such an environment to re-run grub if your boot loader 
has moved or gotten confused.
