I am back and ready to help as much as possible on this issue. When and how do you notice the corruption? I found the corruption during a decompression of a large tarball. During the untarring, the process stopped with an error. Subsequent attempts would stop randomly in the process. I then did a simple fsck on the fs to see if anything was amiss...which is when I discovered the problem...This occurred after 2 months of runtime... Does it have a particular pattern? None that I have found...other then long uptimes... Would it be possible to try a different brand of disk controller in order to rule out the driver being buggy? It is a TX2 which has had some pretty nifty support for a while. However from my understanding of the TX2, it really is not a true hardware controller...in fact, I would have used atacontrol if I could go back in time... -----Original Message----- From: Scott Long [mailto:scottl@samsco.org] Sent: Sunday, June 19, 2005 8:37 PM To: emartinez@crockettint.com Cc: freebsd-fs@freebsd.org Subject: Re: UFS2+Softupdates Corruption Regardless on Seven various systems Edgar Martinez wrote: > All, > > > > I have a network of FBSD boxen running 5.3 w/ 2x PATA WD1200JB Drives and a > Promise Fastrack TX2 controller in mirror.
