Patch can be found here: http://people.freebsd.org/~mav/cam-ata.20100119.patchFeedback as always welcome.
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
