Hi,First of all, I'd like to thank you for the truly excellent geidus, they're very well written.But, I think you're missing explanations on what to do once this is working, which method to use to serve the clients ?For example, I gave NFS a go and I'm running into a Stale NFS File Handle issue. Unlike linux NFS servers, you can't just set the fsid by hand to make them the same between servers. I'm not yet sure how to work around this.Other interesting thing is ZFS-on-HAST-on-a-ZVOL.What the correct way to tweak ZFS to make this work without significant performance loss. There are two ZILs, and 2 write caches here, and syncs are super slow by default.How do typical iscsi clients behave on failovers ?
