[zfs-discuss] convert raidz from osx
I am converting a 4 disk raidz from osx to opensolaris. And I want to keep the data intact. I want zfs to get access to the full disk instead of a slice. I believe like c8d0 instead off c8d0s1. I wanted to do this 1 disk at a time and let it resilver. what is the proper way to do this. I tried, I believe from memory : zpool replace -f rpool c8d1s1 c8d1 but it didn't let me do that. then I tried to put the disk offline first , but same result. Thanks, Dirk -- 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] convert raidz from osx
Dirk, I'm not sure I'm following you exactly but this is what I think you are trying to do: You have a RAIDZ pool that is built with slices and you are trying to convert the slice configuration to whole disks. This isn't possible because you are trying replace the same disk. This is what happens: # zpool create test raidz c0t4d0s0 c0t5d0s0 c0t6d0s0 # zpool replace test c0t6d0s0 c0t6d0 invalid vdev specification use '-f' to override the following errors: /dev/dsk/c0t6d0s0 is part of active ZFS pool test. Please see zpool(1M). You could replace the disk slice with a different disk like this: # zpool replace test c0t6d0s0 c0t7d0 If you don't have any additional disks then I think you will have to backup the data and recreate the pool. Maybe someone else has a better idea. Also, you refer to rpool, which is the default name of the ZFS root pool in the Opensolaris release. This pool cannot be RAIDZ pool nor can it contain whole disks. It must be created with disk slices.

Re: [zfs-discuss] convert raidz from osx
yes, that was what I was doing. I wanted to give the raidz whole disks because grub didn't want to install. ( I forgot which command I used . bootadm ? ) I have another slice free on a shared disk with osx and win7 but I am having problems with grub. I will try that again and document it so I can ask a proper question about it. As the installer has problems and I couldn't get the fdisk workaround to work with the osol-1002-118-x86.iso Dirk On 08 Oct 2009, at 16:03, Cindy Swearingen wrote: Dirk, I'm not sure I'm following you exactly but this is what I think you are trying to do: You have a RAIDZ pool that is built with slices and you are trying to convert the slice configuration to whole disks.
