If you had a hotspare, that would require 3 disks. > The OS is installed and working, and rpool is mirrored on the two disks. I take it you used the entire disks for rpool. You can easily create additional zfs filesystems in there... Simply "zfs create /foo/bar" and then you will have granular snapshot abilities on that sub filesystem, etc. But it will be part of rpool and therefore if users fill up that space, rpool has also filled up. You might benefit by setting either a quota or refquota on the sub-filesystem. You might benefit by setting a reservation or refreservation on the rpool filesystem. Check man zfs for more info. zfs set quota=200m /foo/bar Another option you could pursue if you want: You could partition the disks. Let rpool exist in the first partition, and tank exist in the second partition. This would create a separation of the two pools, which might be beneficial to you. But it's kind of a pain to partition your disk. The level of difficulty varies based on which distribution and which version you're installing. And the last option I can think of: Depending on your HBA, you might be able, in hardware, to split your disks into subvolumes, which appear logically as different disks to the OS. > * Or should I create file-based pools and then create the new filesystems on > them? Don't do that. You'll definitely be better off, by using one of the options I mentioned above. ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Raul, > I must configure a small file server. It only has two disk drives, and they are (forcibly) destined to be used in a mirrored, hot-spare configuration. 2 disks and mirrored *and* a hotspare ...?? Imho you need 3 disks to do this setup. I just wanted to make sure you have your idea's correct before you start. My 2 cents. ..Remco On 9/22/11 6:10 AM, Raúl Valencia wrote: Hi, everyone!

It might be easier if you put it under a sub-filesystem. e.g: rpool/share rpool/share/share1 rpool/share/share2 That way if someday you have more disk, you can just use recursive zfs snapshot and send to copy the data to new pool. Easier than copying the data one by one. -- Fajar ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
