Hello! I've the problem that sometimes there are many disk waiting processes (sysctl -n vm.vmtotal), but systat -vmstat shows da0 and da1 busy with 0-10%.
I guess that the disk i/o is at about 100%, but wondering why I see those strange values. System Information: - Disks are attached to 07:01.0 RAID bus controller: 3ware Inc 9550SX SATA-RAID u0216# uname -a FreeBSD u0216.nshq.netstream.com 6.2-RELEASE FreeBSD 6.2-RELEASE #0: Wed Oct 31 14:53:00 CET 2007 [EMAIL PROTECTED]:/usr/obj/usr/src/sys/SMPPAEQUOTA i386 => kernel contains 3ware patches from CVS, marked for inclusion in 6.3, because we've seen many times a freeze on that system before - Disks are 10k rpm sata disks. - Board is a Supermicro X7DB8, processor is a quad core Xeon, [EMAIL PROTECTED] Anyone an idea, a) why systat -vmstat shows so small busy values? b) how to debug it further?
