Hi all, Check this out: I''ve had created a zpool: zpool create storage mirror c0t2d0 c0t3d0 mirror c0t4d0 c0t5d0 mirror c0t6d0 c2t0d0 mirror c2t1d0 c2t2d0 mirror c2t3d0 c2t4d0 mirror c2t5d0 c2t6d0 [ok no problem] Then when I want to add a log device so I run: zpool add storage log [b]c0t1d0[/b] invalid vdev specification use ''-f'' to override the following errors: /dev/dsk/[b]c2t6d0s0 [/b]is part of active ZFS pool storage. Please see zpool(1M). I''d tried to add c0t1d0 but the error goes to c2t6d0s0... This is a bug ? Im using snv_89. Thanks !!!! This message posted from opensolaris.org
