I just ran zpool scrub on an active pool on an x4170 running S10U7 with the latest patches and iostat immediately dropped to 0 for all the pool devices and all processes associated with that device where hard locked, e.g., kill -9 on a zpool status processes was ineffective. However, other zpool on the system, such as the root pool, continued to work.
Neither init 6 nor reboot where able to take the system all the way down, though reboot did get further. After a hard reset the system came backup cleanly and a subsequent zpool scrub succeeded, but I am now concerned about when it is safe to run a scrub. The most interesting pool action taken before the scrub was attempted was to append another mirror vdev to the pool which already had 2 mirrors in it. Are there known bugs I can track with regards to zpool scrub locking up a system, and if it happens again is there any useful information I can gather before or during the system reset to help track this down further? Thanks. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
