Subject: expanding virtual disk based on lvm
Date: Tue, 28 Aug 2012 13:26:38 -0700 [thread overview]
Message-ID: <1346185598.26275.28.camel@corn.betterworld.us> (raw)
My vm launches with -hda /dev/turtle/VD0 -hdb /dev/turtle/VD1, where VD0
and VD1 are lvm logical volumes. I used lvextend to expand them, but
the VM, started after the expansion, does not seem to see the extra
space.
What do I need to so that the space will be recognized?
The net has references to qemu-resize and virt-resize, but I don't seem
to have them. The host system is on QEMU emulator version 0.13.0
(qemu-kvm-0.13.0), Copyright (c) 2003-2008 Fabrice Bellard from the
Debian I'm on lenny (it's the upgrade I'm testing).
The other problem is that everything on the net refers to files that are
disk images; I'm not sure if the same procedures apply when a logical
volume is the underlying device.
The virtual disks each have 3 partitions. Inside the VM software raid
produces dm0 from the 2 first partitions and dm1 from the 2 third
partitions.
Thanks for any help.
