Hello there; more news on this issue :-( Since broke again after I replaced the power supply and add an extra ahc2940 controller... So, let's recap: - It is not the controller (we replaced the one on the failing bus) - It is not the drives (we've replaced them since the problem started) - It is not the cables (maybe it is - I had to cut longer cables to get what I needed) - It is not a corrupted / file system (the last crash, the drives that went down were not on the same bus as the / ) - It is not power (this is on a dual balanced 350W PSs). - It is not the operating system (2.2.5 2.2-stable 2.2.6 they all do the same thing) Oh, I reduced the bus speed in the spool bus (the one with the problem) from 40mb/s to 20mb/s, and I newfs the partition, just in case. ie, I've disabled. Is there a way I can tell the drives to spin at 5200 rpm instead of 7200 rpm? How solid is ccd ? ================================================== Raul Zighelboim rzig@verio.net > -----Original Message----- > From: Mike Tancsa [SMTP:mike@sentex.net] > Sent: Saturday, April 18, 1998 2:33 PM > To: Raul Zighelboim > Subject: RE: Help !
