Re: [zfs-discuss] How to resize ZFS partion or add a new one?
Frank, I can't comment on everything happening here, but please review the ZFS root partition information in this section: http://www.solarisinternals.com/wiki/index.php/ZFS_Troubleshooting_Guide Replacing/Relabeling the Root Pool Disk The p0 partition identifies the larger Solaris partition, which contains slice 0-8. Slice 0 is then used for your ZFS root pool. Using a p0 device for your root pool was never intended and unexpected behavior could result. I think we have a CR to prevent this configuration in the future. Yes, the findroot entry needs the slice indicator, which is "a" for slice 0: findroot (pool_rpool,1,a) Then make sure the BIOS points to the right boot disk.

Solaris x86 will only access the contents of one "Solaris" partition at a time. Maybe you could format the other partition FAT32 and run ZFS on a file in there, but I can't imagine the peformance would be good doing that. -- Darren ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

I am afraid I won't able to do that because the ZFS partition is around 50 GB and the NTFS one is 20 GB... I am thinking in another possibility. Format the current NTFS partition to ZFS and then I would be able to use this space like another disk, to store the user home for example, or other stuff. Would it be possible?

The Solaris partition must be continuous and at the beginning of the partition. You'd need a tool that could move the data in partition 3 to start at cylinder 12. Since the move distance is less than the size to be moved, you have to do it carefully. I'm not sure what tools are out there that would make that move easy (something like Partition Magic?) You could do it naively with 'dd' (while booted from another disk), but if you crashed in the middle, you'd have problems knowing how to pick up. Better would be to do it in chunks and keep track. Assuming you did that, you could then go through all the hoops to expand the fdisk partition, then expand the VTOC label inside, then make use of the added space. Not something I'd want to attempt without a backup and some testing. -- Darren ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] How to resize ZFS partion or add a new one?
My answer is incomplete. You can use the zpool attach command to attach another disk slice to a root pool's disk slice to expand the pool size after the smaller disk is detached. On Julio's laptop, I don't think think he can attach another fdisk partition to his root pool. I think he needs to backup his pool, reconfigure and expand the solaris2 partition, and then reinstall OpenSolaris.
