From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; Q312461) Description of problem: I have a freshly installed Compaq DL380 with two processors, 2GB of RAM, and four internal 32GB drives. These are RAIDed via an internal RAID card (the standard one that comes with the system) to a 64GB drive, divided into 6 partitions. Running RedHat 7.3, with all errata applied (including the latest kernel, 2.4.18-5), I cannot get an iostat output on the machine. Here is the output of /proc/partitions: $ cat /proc/partitions major minor #blocks name rio rmerge rsect ruse wio wmerge wsect wuse running use aveq 72 0 71122560 ida/c0d0 6267 10109 129032 32370 98478 2539466 21106040 13870540 0 430410 13903170 72 1 1048544 ida/c0d0p1 1381 2427 30458 5300 1829 7001 70752 73600 0 21790 78900 72 2 6340320 ida/c0d0p2 847 1930 21674 4830 2996 2925 49232 163000 0 41500 168090 72 3 4194240 ida/c0d0p3 3890 5633 75626 21480 2654 19639 178880 624700 0 35750 646180 72 4 1 ida/c0d0p4 0 0 0 0 0 0 0 0 0 0 0 72 5 2097104 ida/c0d0p5 3 0 24 30 0 0 0 0 0 30 30 72 6 57442304 ida/c0d0p6 133 80 1146 640 90999 2509901 20807176 13009260 0 373720 13009870 Here is the output of iostat: Linux 2.4.18-5smp (gweb01.aus1.giganews.com) 07/22/2002 Device: tps Blk_read/s Blk_wrtn/s Blk_read Blk_wrtn Getting disk performance readouts is relatively important to use of this server. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.Install server 2.Run iostat 3. Actual Results: No devices are listed Expected Results: Devices on the machine are listed. I expect to get at least the disk stats for dev72-0. Additional info:
What device does this show up as? And does using the version at http://people.redhat.com/teg/ help?
The device doesn't show up as anything. Nothing shows up. The output I gave you is *exactly* what is returned by iostat (ie. no devices listed). The version at http://people.redhat.com/teg/ does not work either. Also, in that file, the log says that the requirement for gnuplot was removed, but it's still in the file, and the RPM still requires it. Rebuilding from source worked, but like I said, iostat doesn't return any device information.
"What device does this show up as?" - scsi? Is it sda? Is it something special to the driver? gnuplot issue fixed (thanks) - removed the file requiring it before, forgot the explicit "Requires: " line.
From the posted info previously: 72 0 71122560 ida/c0d0 6267 10109 129032 32370 98478 2539466 21106040 13870540 0 430410 13903170 So dev72-0 shows up as ida/c0d0, but that's not a mounted partition of course. The drives are mounted like so: /dev/ida/c0d0p1 / ext3 rw 0 0 none /proc proc rw 0 0 none /dev/pts devpts rw,gid=5,mode=620 0 0 /dev/ida/c0d0p6 /news ext3 rw 0 0 none /dev/shm tmpfs rw 0 0 /dev/ida/c0d0p3 /usr ext3 rw 0 0 /dev/ida/c0d0p2 /var ext3 rw 0 We have a Compaq Proliant 8500 which uses the same type of SmartCard running stock RedHat 7.2 (with all applicable errata) and the iostat information shows up as: Device: tps Blk_read/s Blk_wrtn/s Blk_read Blk_wrtn dev72-0 25.00 0.00 240.00 0 1200 That card, too, shows up as ida/c0d0.
This is a followup. I have another single processor DL380 with a PCI SCSI card inside that we hooked a SCSI RAID to. iostat finds the SCSI RAID just fine, but stats for the internal SmartArray card are not shown. I've confirmed that the data is not showing up in /proc/stat On this DL380, I've upgraded the kernel to the latest errata (2.4.18-10). Again, I don't have this problem with similar machines under RedHat 7.2 (2.4.9- 31/34). Those disk I/O stats would be really nice.
Same problem here with a Compaq DL360 running RH7.3 + all updates. Any solution yet?
This appears to be resolved with the latest kernel errata (2.4.18-18.7.x). Anyone else want to verify?
Yes, I believe fixes that went into the latest kernel erratum regarding the kernel's Hz value have resolved this issue. Arjan can you comment?
