Apologies in advance if this be a stupid question, as everything I've
read seems to suggest it's impossible.
Slowly running out of space on a 200GB root partition.
Is it possible to create a snapshot - leaving the QCOW2 image
'quiescent' - resize it using 'qemu-img resize' - then pivot the
snapshot back? (Then shutdown, attach the storage to another bootable
OS, and run fdisk and resize2fs.)
Everything I've read says to shutdown the VM; but besides the real
possibility of the snapshot blockcommit being corrupted when pivoted
into the newly resized backing store, I don't see why it shouldn't work.
And save some significant downtime.
Please can someone advise if this is actually possible, or if I'm
wasting my time?
Thanks!
