What To Do When You Start Getting SCSI Disk Errors
Jul 29th, 2006 by Jon Stahl
One of our servers here at ONE/Northwest (which, among other duties, hosts this blog!) has been acting a little flaky over the past few weeks. The SCSI disk subsystem was throwing intermittent clusters of CRC errors, which seemed to be causing the filesystem to go into read-only mode to protect itself. Which would of course bring down pretty much all of its processes, requiring a restart and an fsck disk check. Not good at all.
After Googling around a bit, and pondering the hassles of SCSI driver upgrades, I decided to just get a can of compressed air, disconnect all the drive cables, blow everything out, then carefully reconnect everything.
Twenty-four hours later, and not a single error. Another day or two and I’ll be satisfied.
It’s nice when the easy fix works.
