Re: [Xen-users] Extremely poor iSCSI performance
I see similar behavior with OCFS2 on my 4 and 2-node clusters. Usually this
happens when I'm creating a new disk file...since OCFS2 does not support sparse
disks it actually creates the whole disk, and I often see large hangs while
this is happening. I suspect that OCFS2 is the cause - I think something about
the file locking on the OCFS2 cluster causes this.
