Are you saying that running in RAID0 mode with this card and
motherboard combination, you get a memory leak? Who is the culprit?
I don't know if it's caused by a memory leak or something else, I'm
just describing what happens. I would be tempted to suspect the RAM
itself if another identical machine didn't have exactly the same
issue.
what's left to try?
Bug report...
I've reported the issue to 3ware but they've not responded. I
replicated the problem with RHEL AS 4 update 5 and contacted RedHat
but they told me evaluation subscriptions aren't supported.
I see there's a new firmware version out today (3ware codeset
9.4.1.3... I guess I'll update it and push the whole thing back up
the hill for another go.
I hope that fixes things for you.
Maybe I'm thinking about this all wrong - maybe this responsiveness
issue won't even arise during normal operation, perhaps it's just a
symptom of intensive benchmarking when all the resources of the
machine are devoted to throwing data at the card/disks as fast as
possible. I'm now way out of my depth, frankly.
I'm going to try the latest firmware upgrade, followed by RHEL/CentOS
5, and finally see if I can replicate with a different card (Areca or
LSI, perhaps).
Thanks for all the feedback, at least I feel as if I've tried every
conceivable obvious thing.
