I've been using the 3Ware cards for 2 years on FreeBSD... We had a drive
go south a few weeks ago, and
the 3dmd (3Ware daemon) reported the problem to me. I had a local hardware
tech go out and
replace the drive, boot up the system, and then over the net, I rebuilt the
array. It was back up

The author of the twe driver, Michael Smith, confirms he
hasn't worked on the driver for several years now.

I openned a case with 3ware tech support and they responded:
We do not support
But the version of 3dmd for FreeBSD is not a current version and lacks
some features found in 3dmd for Linux and Windows. My situation was
that I needed one of the new features in order to rebuild a RAID1 mirror
(ignore errors when rebuilding; my good drive had a bad sector out

Please try linux instead.
So I guess I will try that and see what happens.

Tested with RAID 10 instead of RAID 5, success !
RAID 10 arrays tested: 6xWD200GB and 8xWD200GB both worked
RAID 5 arrays tested: 6xWD200GB and 4xWD200GB both failed
Note: 3ware lists the WD 200GB disk as Under Test. (ie they have not yet
given it a Compatible rating)

Not solved this yet, but I have determined a few things that
the problem isn't. Info at:
http://www.freebsd.uwaterloo.ca/twiki/bin/view/Freebsd/BackupServerProblem
Tested with soft updates off and on, fails in either case, so that
isn't it.
Seems like the problem is either:

I can only hope I don't have the same issue. I'm currently building a 1.75TB
NAS to do daily backups using 3ware 7500-8 and maxtor drives.
Tiny bit more info:
- NFS was starting to be implicated, but on one of my backup servers
I had let it run 2 dumps of
12 matches
