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?
Cheers,
Vic

Why isn''t sharing via NFS or iSCSI practical in your case ? -- Darren J Moffat
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.
