Hi Matt, I don't have a way to reproduce this issue and I don't know why this is failing. Maybe someone else does. I know someone who recently split a root pool running the S11 FCS release without problems.
I'm not a fan of root pools on external USB devices. I haven't tested these steps in a while but you might try these steps instead. Make sure you have a recent snapshot of your rpool on the unhealthy laptop. 1. Ensure that the existing root pool and disks are healthy. # zpool status -x 2. Detach the USB disk. # zpool detach rpool disk-name 3. Connect the USB disk to the new laptop. 4. Force import the pool on the USB disk. # zpool import -f rpool rpool2 5. Device cleanup steps, something like: Boot from media and import rpool2 as rpool. Make sure the device info is visible. Reset BIOS to boot from this disk. On 04/16/12 04:12, Matt Keenan wrote:
Hi Attempting to split a mirrored rpool and fails with error : Unable to split rpool: pool already exists I have a laptop with main disk mirrored to an external USB. However as the laptop is not too healthy I'd like to split the pool into two pools and attach the external drive to another laptop and mirror it to the new laptop. What I did : - Booted laptop into an live DVD - Import the rpool: $ zpool import rpool - Attempt to split : $ zpool split rpool rpool-ext" - Error message shown and split fails : Unable to split rpool: pool already exists - So I tried exporting the pool and re-importing with a different name and I still get the same error. There are no other zpools on the system, both zpool list and zpool export return nothing other than the rpool I've just imported. I'm somewhat stumped... any ideas ? cheers Matt _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
