I set this server up with mfsbsd, which is RC1, and didn't get to update the system yet. This box has 6 hdds, a 2-mirror zpool was set up as the root pool, with 2 spares. While testing hot swapping I noticed that while the controller detects disk removal/insertion, the zpool will never recover. The problem seems to be deeper than ZFS, as disklabel/fdisk/etc also fail on the removed-and-reinserted disk. At the ZFS level, doing a zpool clear yields more errors on the removed disk; rebooting becomes the only option to make the pool healthy again. Is this normal? Did I miss any step? Regards, Hugo
