Hi all we consider using ZFS for various storages (DB, etc). Most features are great, especially the ease of use. Nevertheless, a few questions :
- we are using SAN disks, so most JBOD recommandations dont apply, but I did not find many experiences of zpool of a few terabytes on Luns... anybody ? - we cannot remove a device from a pool. so no way of correcting the attachment of a 200 GB LUN on a 6 TB pool on which oracle runs ... am i the only one worrying ? - on a sun cluster, luns are seen on both nodes. Can we prevent mistakes like creating a pool on already assigned luns ? for example, veritas wants a "force" flag. With ZFS i can do : node1: zpool create X add lun1 lun2 node2 : zpool create Y add lun1 lun2 and then, results are unexpected, but pool X will never switch again ;-) resource and zone are dead. - what could be some interesting tools to test IO perfs ? did someone run iozone and publish baseline, modifications and according results ? well, anyway, thanks to zfs team :D This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
