Hello, I have a server with a weird trashing problem and while investigating on this issue I've found a SCSI error happening 1 hour before the trashng occours. Can someone give me info on this kind of problem (I'm not able to understand Card State Dump). The server has 2 72Gb disks with one partition each mirrored between them with software raid. Thanks, The server is http://www.tyan.com/products/html/gx28b2881.html with B2881G28U4H (Hot-swap U320 SCSI bays) ====== root # uname -a Linux cp3a 2.6.16.19 #2 SMP Mon Jun 5 19:26:39 CEST 2006 i686
