I am not sure if zfs can make two pools in different partitions of the same device though - underneath it still uses Solaris slices, and I think those can be used on one partition. That was my assumption for a long time, though never really tested. I only did similar expansions within one slice table which covered the whole disk, and that was a mirror set so I could juggle data around (migrating to ZFS Root from UFS+LUroot+swap layouts, where sometimes original slices did not all go after each other). That went well, and autoexpansion worked as soon as I increased the slice sizes via format's partition editor. And maybe rebooted too... I think the method of zfs send/recv via a secondary device (including network storage) and another boot device (including a LiveCD|LiveUSB), and remaking the partition, is the least error-prone for this poster's situation. And resizing the system NTFS partition is really unlikely to be allowed from within running Windows. It should be done from some external booting software, and probably after such defragmentation which would stuff all data into start or end of that NTFS partition as appropriate (see for example the free JkDefrag/MyDefrag project). -- ++ || | Климов Евгений, Jim Klimov | | технический директор CTO | | ЗАО ЦОС и ВТ JSC COSHT | || | +7-903-7705859 (cellular) mailto:jimkli...@cos.ru | | CC:ad...@cos.ru,jimkli...@mail.ru | ++ | () ascii ribbon campaign - against html mail | | /\- against microsoft attachments | ++ ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

If one has mirrored disks, you could do something like I explain here WRT partitioning and resizing pools. http://www.kamiogi.net/Kamiogi/Frame_Dragging/Entries/2009/5/19_Everything_in_Its_Place_-_Moving_and_Reorganizing_ZFS_Storage.html I did some shuffling using Solaris partitions here on a home server, but it was using mirrors of the same geometry disks. You might be able to o a similar shuffle using an external USB drive which was appropriately sized and turn on autoexpand.

Re: [zfs-discuss] Resizing ZFS partition, shrinking NTFS?
Hi Clive, What you are asking is not recommended nor supported and could render your ZFS root pool unbootable. (I'm not saying that some expert couldn't do it, but its risky, like data corruption risky.) ZFS expects the partition boundaries to remain the same unless you replace the original disk with another disk, attach another disk and detach the original disk, or expand a pool's an underlying LUN. If you have a larger disk, this is what I would recommend. Attach the larger disk and the detach the smaller disk. The full steps are documented on the solarisinternals.com wiki, ZFS troubleshooting section, replacing the root pool disk steps.

I've used the Knoppix LiveCD against a defragmented NTFS. Then use beadm(1M) to duplicate your OpenSolaris BE to a USB drive and also send snapshots of any other rpool ZFS there. Then I would boot the USB drive, run format, fdisk and recreate the Solaris fdisk partition on your system, recreate the rpool on slice 0 of that fdisk partition, use beadm(1M) to copy your BE back to your new rpool, and then restore any other ZFS from those snapshots.
