It seems to be working fine for me. I'm running SLES8, kernel version 2.4.19-4suse-SMP.
Here's /proc/stat: disk_io: (94,0):(222739,188355,3626408,34384,846536) And a snippet from sar -b: sysaatm2:/proc # sar -b|more Linux 2.4.19-4suse-SMP (sysaatm2) 07/18/03 00:00:01 tps rtps wtps bread/s bwrtn/s 00:10:00 1.17 0.54 0.64 12.88 12.72 00:20:00 3.69 3.04 0.65 62.22 13.96 00:30:00 0.29 0.00 0.29 0.00 4.64 I'll check to see if SuSE has applied their own patches to the kernel source to get it to work or if it's simply a kernel compile option. Will update shortly... Leland
