He wants to mount the ZFS filesystem (I'm assuming off of a backend SAN storage array) to two heads, then round-robin NFS connections between the heads to essentially *double* the throughput. >From what he's described here, it isn't going to work. ZFS isn't a cluster filesystem. You can't currently mount it from two systems at the same time. That is, unless something big has changed recently... I haven't been doing a very good job of keeping up lately, but I think it'd be hard to miss an announcement like that! --Tim
