Looks like staying with CentOS over going to FC2 > is the right course of action for this server! :-) Last week I ricompiled the 3ware driver (7006-2), thank you Scott, to solve a EXT3 errors and now all is ok and functionally, no EXT3 error after a week. But when the server go a load average about 2.0/2.5 the CPU iowait go up to 70-80% ... impressive! I found this thread very interesting: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=121434#c43 but the only solution at my problems is to recompile Kernel with 3ware driver statically compiled in. I ricompiled the Kernel from source ( 2.4.27 ), in a server test, and now the CPU iowait is about 3 - 5 % with the same load av. maurizio
