--KFztAG8eRSV9hGtP Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Having a weird problem, just checking if anyone else has seen something similar and can point me in a direction before I go swapping hardware. Been seeing quite a few hosed files over the last few days, since tossing a pair of Maxtor 80 gig drives into a box here. They are on a separate controller and separate channels (on an older Promise), and the box is running 4.6.2 stable. The drives are mirrored using vinum. I've got the newest bios for both the Promise and the Motherboard. As a test, I dd'ed an empty 500 meg file, then md5'ed it. After waiting about 30 minutes, I md5'ed it again - the checksum had changed. The drives are checking out ok (using the Maxtor utilities) and vinum reports no errors whatsoever. Smaller files (text and binary) seem unaffected. Anything over 5 megs is corrupted after a seemingly random amount of time. After waiting over a day, the md5 checksum hadn't changed again, after the initial scrambling. This has me pretty well stumped, and I'm about to swap controller and cables - just curious if anyone has dealt with something like this in the past, and/or can steer me down better troubleshooting path. -Mahlon Mahlon E.
