hi, after we switch our servers from centos-3 to centos-4 (aka. rhel-4) one of our server always crash once a week without any oops. this happneds with both the normal kernel-2.6.9-11.EL and kernel-2.6.9-11.106.unsupported. after we change the motherboard, the raid contorller and the cables too we still got it. finally we start netdump and last but not least yesterday we got a crash log and a core file. it seems there is a bug in the raid5 code of the kernel. this is our backup server with 8 x 200GB hdd in a raid5 (for the data) plus 2 x 40GB hdd in raid1 (for the system) with 3ware 8xxx raid contorller, running. i attached the netdump log of the last crash. how can i fix it? yours. -- Levente "Si vis pacem para bellum!" -------------- next part -------------- An embedded and charset-unspecified text was scrubbed...
