Hi, I'm installing SLES10SP1 on a Proliant DL380 G5 to run Xen Domains. Later, another machine will join the party, so I can have two Xen hosts to move back and forth the VMs on the fly. The thing is, in a perfect world I would have a single LUN for all my VMs and would use a cluster aware LVM solution to assign disks for the domains. Back to reality, I don't want to use EVMS, since it adds another layer of complexity and will be dropped in future releases of the distro. Are there any other options than the next two?: - Use a big LUN with OCFS2 to host file based images, losing performance & flexibility (i don't like it) - Nag the SAN admin every time I need to add a new domain, so he creates a new LUN for me (a 500GB, 20GB or 1GB one, who knows), keeping performance, but losing flexibility (and maybe even wasting disk space). Another question, can I use lvm inside paravirtual domains?, all the guides I found advice to create volumes outside the domain to assing them to FS, example: /dev/vmdisks/dom0-root /dev/vmdisks/dom1-root /dev/vmdisks/dom0-home /dev/vmdisks/dom1-home /dev/vmdisks/dom0-var /dev/vmdisks/dom1-var /dev/vmdisks/dom0-usr /dev/vmdisks/dom1-usr But this way I won't be able to have domains on different hosts, (a safe way at least, since I need this to be reliable) Regards, Ciro _______________________________________________ suse-sles-e mailing list [email protected] http://listx.novell.com/mailman/listinfo/suse-sles-e
