Hello, Thank you for this very interesting thread !
I want to confirm that Synchronous Distributed Storage is main goal when using ZFS ! The target architecture is 1 local drive, and 2 (or more) remote iSCSI targets, with ZFS being the iSCSI initiator. System is designed/cut so that local disk can handle all needed performance with good margin, as each one of iSCSI targets through large enough Ethernet fibers. I need that any network problem doesn't slow the readings on local disk, and that writings are stopped only if not any remote are available after a time-out. I also did a comment on that subject in : http://blogs.sun.com/roch/entry/using_zfs_as_a_network To myxiplx : we called "Sleeping Failure" a failure of 1 part, that is hidden by redundancy but not detected by monitoring. These are the most dangerous... Would anybody be interested by supporting an opensource "projectseed" called MiSCSI ? This is for Multicast iSCSI, so that only 1 writing from initiator be propagated by network to all suscribed targets, with dynamic suscribing and "resilvering" being delegated to remote targets. I would even prefer this behaviour already exists in ZFS :-) Please let me any comment if interested, i may send a draft for RFP...
