Do you mean I have to run the dd on the whole disk without interruption? That's gonna be very long on 1TB disks! Isn't there any short way to clear both the label, start and end of the disk? ---------------------------------------------------------------------------------------- Sonicle S.r.l. : http://www.sonicle.com Music: http://www.gabrielebulfon.com Quantum Mechanics : http://www.cdbaby.com/cd/gabrielebulfon Da: Garrett D'Amore A: disc...@lists.illumos.org Cc: Aldo Fornoni Data: 1 aprile 2016 18.55.00 CEST Oggetto: Re: [discuss] converting adpatec volume to jbod cannot replace Did you erase the *whole* disk? (label and both start and end of disk?) Otherwise I’m out of ideas — the only thing it could know about at that point would be the WWN or some such, but I don’t see why it would care unless you actually do have a pool configuration that still references it.

I did the "dd if=/dev/zero of=/dev/....", did the fdisk remove/create partition...no way :( Only if I change the disk phisically in between the volume2jbod, the it will work. How can this be? Any other way to let it think it's another disk and forget about the replacing one? ---------------------------------------------------------------------------------------- Sonicle S.r.l. : http://www.sonicle.com Music: http://www.gabrielebulfon.com Quantum Mechanics : http://www.cdbaby.com/cd/gabrielebulfon Da: Garrett D'Amore garr...@damore.org A: disc...@lists.illumos.org Cc: Aldo Fornoni aldo.forn...@unidatech.it Data: 1 aprile 2016 18.07.28 CEST Oggetto: Re: [discuss] converting adpatec volume to jbod cannot replace If you have a backup, you can try destroying the label on the disk you’re adding. I think its likely that zpool is seeing the ZFS label or other data on the drive and trying to be paranoid to prevent you from clobbering useful data on the drive. dd from /dev/zero to the drive can clear that up (but again, make sure you have a backup in case something goes wrong!)

One by one I would like to: - offline the vdev on the pool - through arcconf remove the volume, initialize and create it as jbod - zpool replace the old vdev with the new vdev Everytime I get to the last point, zfs cannot use the target device as busy, or "part of active ZFS pool data". No "-f" solve the problem. I'm using a prototype machine before using the destination one. If I destroy the pool and recreate through "-f" correctly. Looks like because the replaced disk is actually the same, but with a different vdev, something goes wrong. Any idea?
