Please could you try to reproduce this bug with the latest devel version of sysstat - sysstat-6.0.1-3.2.1. I've installed the currently available development version - sysstat-7.0.0-1 - and it shows zero results too: $ iostat Linux 2.6.17-1.2142_FC4 (hostname) 08/24/2006 avg-cpu: %user %nice %system %iowait %steal %idle 12.54 3.01 4.76 2.96 0.00 76.73 Device: tps Blk_read/s Blk_wrtn/s Blk_read Blk_wrtn cciss/c0d0 39.13 0.00 0.00 0 0 This is on Fedora Core 4. Also, I've tested this on Fedora Core 5, where sysstat is at version 6.0.1-3.2.1. Same results: # iostat Linux 2.6.17-1.2157_FC5xen0 (hostname2) 08/24/2006 avg-cpu: %user %nice %system %iowait %idle 25.02 0.00 0.03 0.72 74.23 Device: tps Blk_read/s Blk_wrtn/s Blk_read Blk_wrtn cciss/c0d0 29.29 0.00 0.00 0 0 Both machines have x86_64 architecture (HP ProLiant 385 servers). I can't reproduce this problem, coud you please try to reproduce this problem with the test package (http://people.redhat.com/varekova/sysstat-7.0.0-2.test.src.rpm or http://people.redhat.com/varekova/sysstat-7.0.0-2.test.x86_64.rpm) - there are add auxiliary outputs which should help to detect the problem. Here are the results from the modified sysstat: # iostat Linux 2.6.17-1.2157_FC5xen0 (hostname) 11/03/2006 avg-cpu: %user %nice %system %iowait %steal %idle 0.12 0.00 0.06 0.78 0.03 99.01 Device: tps Blk_read/s Blk_wrtn/s Blk_read Blk_wrtn cciss/c0d0 52.43 0.00 0.00 0 0 a0 - dk_drive 0 6351816 a1 - dk_drive_rblk 0 6372454 a2 - dk_drive_wblk 0 2863371480 a3 - itv 38979274 fctr 1 rd_sec 0 wr_sec 0 Thank you. Please could you run one more test version: (http://people.redhat.com/varekova/sysstat-7.0.2-2.test2.src.rpm or http://people.redhat.com/varekova/sysstat-7.0.2-2.test2.x86_64.rpm) - there are more outputs. Here are the results with sysstat-7.0.2-2.test2: # iostat Linux 2.6.17-1.2157_FC5xen0 (hostname) 11/08/2006 avg-cpu: %user %nice %system %iowait %steal %idle 0.09 0.00 0.05 0.62 0.03 99.21 Device: tps Blk_read/s Blk_wrtn/s Blk_read Blk_wrtn cciss/c0d0 37.99 0.00 0.00 0 0 a0 - 0 0 0 5353993 a1 - 0 0 a2 - 0 0 a3 - itv 82379863 fctr 1 rd_sec 0 wr_sec 0 Thank for your help, but there will be need one last test - could you please run http://people.redhat.com/varekova/iostat.test and attach the output (it is for x86_64), thaks. Not much success: # ./iostat.test Floating point exception Note that I'm on Fedora Core 5. I had to rebuild all the test SRPMS to get binary ones that work. Thanks for your response. The test srpm is on http://people.redhat.com/varekova/sysstat-7.0.2-2.test3.src.rpm. Done: # iostat Linux 2.6.18-1.2200.fc5xen0 (hostname) 11/23/2006 avg-cpu: %user %nice %system %iowait %steal %idle 0.05 0.00 0.03 0.61 0.03 99.27 Device: tps Blk_read/s Blk_wrtn/s Blk_read Blk_wrtn cciss/c0d0 29.08 0.00 0.00 0 0 a0 - 0 29461524 0 5102268 a1 - 0 0 a2 - 0 0 a3 - itv 118867750 fctr 1 rd_sec 0 wr_sec 0 sysstat works right, there is a problem with the values which which are written in /proc directory. FYI, here's the output on kernel 2.6.20-1.2316.fc5xen0: Linux 2.6.20-1.2316.fc5xen0 (hostname) 09/07/2007 avg-cpu: %user %nice %system %iowait %steal %idle 0.07 0.00 0.03 1.64 0.02 98.24 Device: tps Blk_read/s Blk_wrtn/s Blk_read Blk_wrtn cciss/c0d0 54.25 1252.95 430.85 4491065703 1544333552 a0 - 0 138831890 0 55622089 a1 - 0 4491065703 a2 - 0 1544333552 a3 - itv 358439069 fctr 1 rd_sec 4491065703 wr_sec 1544333552 Seems fixed with new kernel release.
