[zfs-discuss] Re: Re: Unbootable system recovery
Well, the drives technically didn't malfunction. Like I said, the reason why I had to pull the drives out is because 70 lbs is a little TOO much for me to be able to lift. The drives aren't more than 3 weeks old, with a DOM of Jul 2006. Is there anything that I can do to find out how the system was scanning the drives (i.e. as I recall, during the installation, c0t7d0 was listed as the first device. Is there a way to look at the order that the drives were brought online, and maybe I would be able to correlate that to the drive/port map on the controller.) I am banking on that it's SOMETHING related to when I had to plug the drives back in after moving the unit, because I didnt' tag the individual cables for the drives.

If that is the case, then ZFS would automatically figure out the new mapping. (Of course, there could be an undiscovered bug in that code.) --matt ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Hi, Like what matt said, unless there is a bug in code, zfs should automatically figure out the drive mappings. The real problem as I see is using 16 drives in single raidz... which means if two drives malfunction, you're out of luck. (raidz2 would survive 2 drives... but still I believe 16 drives is too much). May I suggest you re-check the cabling as drive going bad might be related to that... or even changing the power supply (I got burnt that way). It might just be an intermittent drive malfunction. You might also surface scan the drives and rule out bad sectors. Good luck :) PS: When you get your data back, do switch to raidz2 or mirrored config that can survive loss of more than 1 disk. My experience (which is not much) shows it doesn't take much to render more than one disk out of 20 or so... especially when moving them. - Akhilesh This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
