comment ZFS on FreeBSD: recovery from data corruption
Thanks for that tip! :-) I was looking into OpenSolaris back in 2009 or so when I started this whole ZFS business, but unfortunately, it did not support the controllers I'm using - this is consumer grade hardware after all. Just recently, I've also looked at OpenIndiana, but I'm not sure if the situation has changed. I might upgrade the controllers to SAS at some stage and consider migrating then.

yep, that's a very good point! and it's also the reason why i haven't updated this article with my progress yet - still busy clearing out replacement hard drives...

comment same harddrive on the same controller, but different cylinder/head/sector
serial numbers as reported by GSmartControl: 6VPAR7SL and 6VPCY3TX. Don't think that gives any clues without some Seagate hard drive production facility database, does it ?

comment same harddrive on the same controller, but different cylinder/head/sector
thanks for the insight! I see I can ignore the issure. Still feels weird that there's different geometries for seemingly identical harddrives, especially as yet another pair of identical drives is reported with the same geometry - and moreover, the CHS values seem to change after I moved from GPT back to a DOS partition...

comment ZFS on FreeBSD: upgrade from 7.x to 8.2?
thanks for the info! :-) I actually did assume ZFS is indeed backwards compatible, but I could not import the pools on the 8.x system, so I asked just to double-check. It seems however I can not import them on the original 7.2 system either, so the pools themselves are the root of the problem, not the new system. BTW: on the original 7.2 system: ZFS filesystem version 6, ZFS storage pool version 6 (just for completeness sake)

comment linux freezes - how to find out if hardware or software is the cause?
OpenSUSE ran the entire night. Trying out Kubuntu 10.04 32 bit right now, but the difference is already visible. Seems like this is not hardware-related, it's Kubuntu 10.04 64bit freezing. I really feel kinda stupid right now - but then, I never had any Linux just freeze without any further message, unless there was a hardware issue...
