Problem solved... after the resilvers completed, the status reported that the filesystem needed an upgrade.
I did a zpool upgrade -a, and after that completed and there was no resilvering going on, the zpool add ran successfully. I would like to suggest, however, that the behavior be fixed -- it should report something more intelligent, either "cannot add to pool during resilver", or "cannot add to pool until the filesystem is upgraded", whichever is correct, instead of dumping core. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
