Error messages and data corruption

[Dan Wilder]

Has anybody run bonnie++ on the 2850 with HW RAID-5 and RAID-10?

Back before 3Ware got their act together, bonnie++ did a pretty good job
of eliciting failures in minutes on their cards, which took days or
weeks to see under normal heavy load.

Interesting and horrifing somehow.

The Server was running fine for one year before our problems started.
And this includes the RAID10 configuration. So I guess the RAID10 cannot
be as unstable as I fear it to be. 

Ok, load on the server has risen since we bought the server, as I read
some comments suggesting the driver/hwardware becoming instable under
higher load.
