Re: [zfs-discuss] Shared Pools in ZFS
Hi Thanks for your answer. We use iSCSI and NFS for some data but the disk I have in mind are the ones we use for our production databases where latency and IOPS require us to use direct attach.

No for exactly the same reasons that ZFS isn't a cluster filesystem. Why isn't sharing via NFS or iSCSI practical in your case ? -- Darren J Moffat ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
[zfs-discuss] Shared Pools in ZFS
Hi All, I went to storage expo in the UK yesterday. During a long train journey back to the west country boss and I were discussing the joys of storage management in a production environment and where ZFS would be able to help. Whilst it would be great if ZFS were a clustered file-system and able to share its pools and file systems read/write across multiple hosts, what would be almost as good would be a shared pool where specific hosts could write to specific file systems. In that way we could use all of the goodies of pool management, tiered storage, migration etc without the metadata overhead of shared locks. Is this feasible?
