Does prtvtoc help? I thought ZFS was nowadays able to copy with mirroring "identical" disks which differed by a number of blocks.

Thanks... very helpful. I noticed though that once a disk is formatted or put into a zpool the cyl no. is no longer given, but then the size is shown I did also find a diffeent answer too. `iostat -En ' Appears to give both the names and the sizes.

[OpenIndiana-discuss] find size of raw disks
Is there some way to determine the size of disks discovered with `format' An attempt to create a 2 disk mirror failed with the message that the disks were different sizes, but I thought they were the same size... I must have used the wrong identifier for one of the disks... so to find the matching disk how can I tell what size the discs turned up by format are? ___ OpenIndiana-discuss mailing list OpenIndiana-discuss@openindiana.org http://openindiana.org/mailman/listinfo/openindiana-discuss
