controller, using the libata sata_sx4 driver. Individual writes to the drivesFWIW at <$dayjob> we have had exactly the same issues using Win2k (ugh) and Promise's own drivers on a Dual Opteron system (Rioworks HDAMA) with an integrated Fastrak S150TX4 controller. Relatively stable using a single drive as a separate volume (our application prefers a RAID 0 stripe), but random subtle corruptions when using an array (striped or mirrored). This is both using the controller's embedded RAID and W2K's software RAID (with the Promise configured to present separate disks). Firmware upgrades/downgrades were tried with no luck. We have two identically configured machines that both exhibit the same problem.
are fine. When the drives are written to simultaneously, either by multiple cp
threads or assembling them in a raid 5, corruption occurs as evidenced by fsck
errors and inconsistent md5 sums.
