Again, thanks a lot for your ongoing great work! The patch doesn't cleanly apply with vpo, but I don't use vpo so I didn't care. Otherwise I couldn't find any problems. The system detects reinserted SATA drives on ICH9 fine. This was tested on a zfs backup server which went to the backbone yesterday, so I can't physically remove any devices any more for testing... But I had some questions about zfs raidz states. I think that isn't a matter of atacam but if I removed one disk, zpool status still showed me the ada3 device "online". After reinserting (and proper detection/initialisazion with cam, ada3 was present again) and zpool clean, it set the devicea as UNAVAIL sinve I/O errors. I coudn't get the device into the pool again, no matter what I tried. Only rebooting the machine helped. Then I could clean and scrub. What are the needed steps to provide a reinsterted hard disk to geom? With the latest patches I don't need to issue any reset/rescan comman, right? So it's a zfs problem, right? My mistake in understanding? Thanks, -Harry [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.13 (FreeBSD) iEYEARECAAYFAktZfLsACgkQLDqVQ9VXb8h6ywCgleNs3+7wtinOt4D+b+XKJtQs I5EAoJ2VkP8NmHzUxEl4AOHN4Q+TcoTq =82Q7 -----END PGP SIGNATURE-----
