Very interesting reading - thanks for the link. Some of those posts
suggest that the newer 3Ware firmware may "improve" the issue.
Otherwise, I guess I'm in the market for a different 4 channel RAID 5
SATA card. Any recommendations?
I am running an Adaptec 2410SA 4 port SATA raid card on x86_64 in FC4
and have had no problems since the third or fourth kernel update of
FC3. I recently copied my entire array to another network server,
upgraded my firmware on the card and rebuilt the array, and copied
everything back... about 200GB. My only trouble is that I can't seem to
get the raid tools working. But I haven't really been working on that
since about mid FC3.
