Hi, I wonder if there is anything else I could do here to find out what might be the problem.
I get plenty of errors like this on the console: psycho0: correctable DMA error AFAR 47b8c200 AFSR 406200ff00800000 psycho0: correctable DMA error AFAR 47b90aa8 AFSR 4062ff00a0800000 psycho0: correctable DMA error AFAR 47b945e0 AFSR 486200ff80800000 psycho0: correctable DMA error AFAR 47b980f0 AFSR 486200ffc0800000 psycho0: correctable DMA error AFAR 47b9c098 AFSR 4862ff0060800000 psycho0: correctable DMA error AFAR 47ba0028 AFSR 4062ff00a0800000 psycho0: correctable DMA error AFAR 47ba4018 AFSR 4862ff0060800000 psycho0: correctable DMA error AFAR 47ba8038 AFSR 4862ff00e0800000 psycho0: correctable DMA error AFAR 47bac010 AFSR 406200ff40800000 psycho0: correctable DMA error AFAR 47bb00d8 AFSR 4862ff0060800000 Even if that doesn't really have anything to do with it, I replace the drive just in case with a brand new one to see. Same results. Searching on google I only came up with a diff that was put in lace in July 2008 here: http://www.openbsd.org/cgi-bin/cvsweb/src/sys/arch/sparc64/dev/psycho.c.diff?r1=1.61;r2=1.62;f=h That from the archive on tech@ point to the same problem and address this to at a minimum clear these errors and keep going. Is this really hardware failure, or bad driver may be somehow? I can get these by doing a fresh install from scratch, do newfs and I can create these errors as well sometime by just doing something like this for testing: dd if=/dev/zero of=/free/test count=1000 bs=1m Not really sure what it really mean here and it happens on one server only so far but not on plenty of others of the same model. Sun V100. dmesg below if needed, but it's the same as others. The drive is 160GB and less then 137GB is use in disklabel, the rest simply through away like many others system like this. 49 others have the same drive no problem. But doesn't appear to be a drive issue anyway. The server does hang time to time. Any clue would be welcome.
