[zfs-discuss] zfs and Dynamic Reconfiguration support?
Hi Hope this is the correct forum for my questions. I have 3 x m9000''s and 2 x m5000''s, Which I would like to use ZFS root/boot disks with support for Dynamic Reconfiguration. Sun SPARC Enterprise M8000/M9000 Servers Product Notes for XCP Version 1040 reports this issue as being broken. Sun SPARC Enterprise M8000/M9000 Servers Product Notes for XCP Version 1041 reports this issue as having a work around. The bug is detailed here, with the work around: http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6522017 According to FUJITSU Europe, there are no customers in Europe using ZFS on M series servers and cannot confirm whether they will support me or not, they have recommended I remain on UFS. Can anyone confirm that they are running M series servers with ZFS boot disks and are currently using dynamic reconfiguration with the work around in a large production environment? If so, would you recommend doing so? Is there anything I should look out for? Are there any performance implications for using ZFS rather than UFS boot disks? Lastly have there been any improvements with regards to ZFS running large oracle database 5TB to 10TB? Last time we investigated performance was said to be very poor. Currently we are using SF, however we would like to start considering using ZFS for some of our smaller environments.
