Hello List,
I tried gvinum RAID-5 with a 5-Stable around the time when 5.1 or 5.2
was released (afair) and back then it basically sucked big time. Raid
worked as long as nothing failed, but reconstructing a drive was
somewhere between very painful and not possible.
Now I will have to upgrade hardware soon, which means I could switch
from NetBSD (and Raidframe) to FreeBSD (with gvinum) again. I would
like to because NetBSD seems to have some kind of memory leak in
connection with Samba and large or many files, but I'd rather have a
somewhat unstable Samba than an unstable Raid, so what's the state of
affairs?

I'm about to try; I have my home server stuck at 4.11 because I could
never get gvinum to work reliably with 5.x, and the drives I had wouldn't
work with two different hardware RAID controllers (ex EMC ST446xxx's,
a DPT/Adaptec controller and a LSI controller - apparently only certain
EMC BIOS versions will work, and I don't have them).
I did find a posting by someone who installed gvinum/RAID5 recently
(under
6.X) but there was nothing about stability.

I'm running gvinum on a PowerEdge 2450 with an external Adaptec SCSI
card connected to a PowerVault 712 (I think, at least an old one), also
running RAID 5. This runs on FreeBSD 6.1. It was not that hard to set it
up, as the handbook has well written documentation about it. However,
there is one thing you should know: Never, ever, edit the gvinum config
file directly when you want to remove drives from your array. Use the
gvinum shell for that. Immediately removing them from the config file
will cause kernel panics. In fact, only use the config file to define
your array: Make changes via the shell. Maybe it sounds logic to you,
but I had about 10 kernel panics before I figured that out.
Overall if you follow exactly what's being said in the documentation it
is quite okay, but my gvinum installation is still missing features. The
Google Summer of Code project has invested quite a lot of time in fixing
the missing features in gvinum, so overall I think it should be a fairly
complete suite now. I'm not sure if those changes are already commited
to the source tree, but I guess they are.
My gvinum installation certainly is stable, however. And the server is
fairly important, so I can't risk upgrading gvinum and maybe ruin the array.
