Re: [Xen-users] Shared volume: Software-ISCSI or GFS or OCFS2?

["Nick Couchman" <Nick.Couchman@xxxxxxxxx>]

Well, I'm not sure it's a matter of iSCSI OR a filesystem, but that depends on how you decide to go about setting it up.  In my environment, I have both iSCSI and FC access to the same volumes.  Some of my servers have FC HBAs and connect to my XEN volume that way, some of them have hardware iSCSI HBAs, and some of them use software iSCSI initiators.  I have three XEN volumes - one for server domUs, one for VDI domUs, and one for development domUs.  All of these volumes are formatted with OCFS2 so that I can mount them on all of my servers.  The domUs then use file-based disks that reside on the shared volumes, so I can migrate them back and forth between servers relatively easily.

You could use iSCSI to do individual volumes for each of your domUs - I found it a bit cumbersome to have to go into either EVMS or LVM each time I wanted to create a domU and create a volume for it, so I'm sticking with the file-based approach.

Hello list,

I want to use shared volumes between severall vm's and defenetly don't
want to use NFS or Samba!

So i have three options:
1. simulated(software-) iscsi
2. GFS
3. OCFS2

What do you suggest and why?

Kind regards, Florian
