I know what you mean but I think this write-up is a bit too harsh. As long as the goal is to get _as reliable as possible_ without spending too much money, I think software RAID has its niche. Besides, I've seen a few hardware RAID controllers having issues themselves (and they weren't the cheapest ones available either). > One can only hope that gvinum actually works in 6 vs the buggy and > incomplete alpha code that shipped in 5.x.

I haven't seen this (luckily!). I do know that sometime in 5.x there was a RAID-5 bug in gvinum but then again the whole vinum/gvinum transition was pretty dodgy back then. This is why I waited until 6.x to migrate. > I'd strongly suggest anyone using GEOM raid to do some > fault insertion testing of their setup prior to actually relying on it. I did. It worked. --Stijn -- There are of course many problems connected with life, of which some of the most popular are 'Why are people born?', 'Why do they die?', and `Why do they spend so much of the intervening time wearing digital watches?' -- Douglas Adams, "The Hitchhikers Guide To The Galaxy" [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (FreeBSD) iD8DBQFDmU7OY3r/tLQmfWcRAryUAJoCHOjyFMKZrrq0/yPzdmcOj0xq0QCfbjMB Yo6ANci/i2latxjOZlUt3WY= =R8BN -----END PGP SIGNATURE-----
