For my purpose I am going to have to create a new zpool with some new disks in and clone a zone to increase its size. I can't just add another raidz set of disks as we are quite strict on how much storage I call allocate (gets charged back). Thanks for the replies.

[zfs-discuss] Best way to expand a raidz pool
Having looked through the forum I gather that you cannot just add an additional device to to raidz pool. This being the case is what are the alternatives that I could to expand a raidz pool?

Re: [zfs-discuss] Best way to expand a raidz pool
Thats not easy for me, I have all the storage spilt up into the same size LUNS so I can't allocate larger luns and the vdev (looking at previous posts) won't give the raid protection. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Re: [zfs-discuss] Change a zpool to raidz
Thats fair enough, pity there isn't a simpler way. Many thanks -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
[zfs-discuss] ZFS and oracle on SAN disks
I believe the best practice is to use seperate disks/zpool for oracle database files as the record size needs to be set the same as the db block size - when using a jbod or internal disks. If the server is using a large SAN LUN can anybody see any issues if there is only one zpool and the dataset is set to have the record size set rather than at the zpool level?
