Re: [Xen-users] domU discs: file vs. volumemanager

["Tijl Van den Broeck" <subspawn@xxxxxxxxx>]

Multipath should be possible with multipath-tools and evms (>2.3.5), see http://www.kernel.org/pub/scm/linux/storage/multipath-tools/ and http://evms.sourceforge.net/user_guide/#multipath that ought to put you on your way.

The "easiest" filesystem that's pretty good in resizing on linux is ReiserFS 3.6 (4 is still to unstable). You can use EVMS to manage the domU disks and simply run resize_reiserfs /dev/... and resize the disks online (I don't think Xen will give trouble over that, since I think you can resize from inside a domU, not 100% sure though).

Hello,
we're currently using xen on 4 boxes connected to a san with a shared
ocfs2 lun.
the domU's all have their discs kept as file.

now my question is, whats a good - meaning stable - way to resize them
on demand ?
or even better to still keep them in files, make them resizeable and let
the files
grow as the disc inside is used. (like virtual server does, imho)

Can EVMS handle this ? Can EVMS also handle multipath SAN Connections ?

Thanks for any suggestions,
