im playing around with Xen and FC5. There is one thing i dont get working.
When i resize a logical volume in dom0 with lvextend, and this volume is
used and mounted in a domU, it seems that the domU does not notice the new
size of the partition until rebooted.
stupid question: did you resize the filesystem after extending the logical
volume ?
yes, id did this. Even if its not resized, the changes are not even
recognized by fdisk when i do a partprobe as David Robinson suggested.
this works for me:
- shutdown DomU
- extend LV in Dom0
- extend filesystem in Dom0
- restart (create) domU
This works because the dom0 knows about the new size immediatly. But
what i wanted to do is a resize without restarting the domU.
Should this work somehow without rebooting the domU, or is this the
intended behavior?
in theory, with a filesystem that allows online-resizing (see link above), it
shouldn't be necessary to shutdown DomU. But haven't tried yet.
Well, i could not find any statement in the docu that really tells me
that this would work. On the other side i could not find a statement
that tells me it wont work. :)
I think, i could create a volume goup inside of a domU and add space to the
domU by adding new block devices and adding their space to the volume
group. But is this really a clever way of doing this, or are there any
easier ways?
extending the logical volume in Dom0 is surely a more elegant approach.
Agreed, this approach is not very elegant, but it seems its the only
currently possible way to extend a domU fs without a restart.
ciao,
Heinz
