This will also include an upgrade to Sun Cluster 3.2, which is where the ZFS support arrives. You will need to copy the data, which is also the safest way of performing such upgrades. The docs are now online at docs.sun.com and you will be especially interested in the upgrade requirements http://docs.sun.com/app/docs/doc/819-2970/6n57ljhoo?a=view > Also, I am considering what type of zpools to create. > I have a SAN with T3Bs and SE3511s.

I would recommend mirrored zpools, though I'll admit to being biased. The important point to remember is that ZFS can correct data problems if it has access to data redundancy. By default, it will only have redundant metadata. If you want redundant data, then you'll want to let ZFS mirror across your storage LUNs. For the truly risk averse, having the LUNs also RAIDed in the array is a good idea. > We are at the extreme start of this project and I was > hoping for some guidance as to what direction to > start. Well, since you've CCed most of the OpenSolaris forums, I'd suggest following up on the ZFS forum (where some of the appropriate people hang out) and the Sun Clustering forums (where more general clustering folks hang out) at: http://www.opensolaris.org/jive/forum.jspa?forumID=80 http://forum.java.sun.com/forum.jspa?forumID=842 -- richard This message posted from opensolaris.org _______________________________________________ storage-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/storage-discuss
