Hi Tim, I looked up the sil3114 controller and I found this CR:
http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6813171 sil3114 sata controller not supported If you can see this disk with format, then I guess I'm less uneasy, but due to the hardware support issue, you might try to create a test pool first like this to see if this disk is usable: # zpool create test c6d1 The "c6d1p0" device is the fdisk partition so just use "c6d1" instead. Then, write and read some data to this pool. If this works, then destroy test and use zpool replace to replace the troublesome disk in your main pool as you identified: # zpool replace storage c3t1d0 c6d1 I don't think ZFS cares if the devices are SATA1 and SATAII. I wonder if anyone else is using this controller/disk and can comment. Thanks, Cindy On 12/18/09 02:34, Tim wrote:
I tried to buy another drive today (750GB or 1TB) to swap out c3t1d0 (750GB) but could not find one quickly. So I was thinking as a temporary measure to use my 1.5TB disk instead as it can be reused at the moment (is currently attached to a sil3114 controller - c6d1p0). Would it be ok to do a zpool replace with this 1.5TB disk attached to the sil3114 controller (it's only a SATA1 controller, whereas motherboard ports are SATAII): "zpool replace storage c3t1d0 c6d1p0" or should I just physically disconnect the sus 750GB drive (c3t1d0) and plug the 1.5TB disk to that port and then run: "zpool replace storage c3t1d0" What's the best approach ? And can you confirm the correct steps to take please. If it's the latter option, do I need to do anything with taking the pool offline at all, or is it just a matter of shutting the box down, swap cables over, start it up and when it comes up degraded (assuming it will), I then run the zpool replace command. I'm feeling a little uneasy about the whole thing, as I have no other backup at the moment other then this array being RAIDZ...my 1.5TB disk was to be a 2nd copy/backup of most of the RAIDZ data (not the best backup, but at least something) but to date I can't read well from the RAIDZ pool to do that backup..and it's a few years of home video. I think I'd just fall to pieces if I lost it. I'd greatly appreciate the advice. Tim
