[TriLUG] Linux Virtualization - Shared filesystems.

[Matt Pusateri]

For virtualization I’ve mostly used VMware with VMFS as that’s the 800lb gorilla and most companies won’t think of using something else in production.  I have used Xen and Xensource, but only with local disks or NFS.  I now find myself being able to deploy KVM, Xen/Xensource/Citrix, etc.  But we want to reuse our existing Fiber Channel san for shared storage.  This brings me to the question of what people are using that’s equivalent to VMFS, for shared Linux Virtualization file storage?  GFS2? OCFS2? I’ve heard GFS2 clusters are a nightmare to maintain, but that was a couple of years ago and things could have changed.  I could build a NFS head off my SAN, but I was trying to avoid that. 


Thanks,
