Description Vladimir Nicolici 2006-05-08 06:20:43 UTC

[1.] One line summary of the problem:    

	wrong value for avgqu-sz

[2.] Full description of the problem/report:

	I have a linux server with 2 disk controllers: a serverworks sata 
controler, with 2 disks, and a LSI Logic SCSI controller, with 16 disks. 

	The iostat statisics work fine for the 16 disks on the scsi 
controller, but the avgqu-sz keeps growing with each request for the 2 disks 
on the sata controller. Also, for those two disks the %util is always 100%, 
even when the machine is completely idle. This generates false alarms from 
Oracle Enterprise Manager that is monitoring those disks.

	The 2 sata disks are in a md raid1 volume with 2 partitions: the root 
partition and the boot partition;

	The 16 disks on the SCSI controller are used by Oracle ASM, through 
raw devices;

	Except for the broken statistics, the system doesn't seem to have any 
other problems, but I am afraid that it will crash once it's deployed in 
production, and avgqu-sz will reach a very large value.

	See [7.7.] for a sample iostat output.

[X.] Other notes, patches, fixes, workarounds:

The kernel has this patch applied: http://lkml.org/lkml/2006/3/21/42 , because 
without this patch Oracle freezes when any disk used by ASM has problems. 
However, the iostat behaviour is the same with or without this patch.

I tried installing a vanilla kernel on the system to reproduce the problem, 
but I gave up after 6 hours of frustating errors. (it was on of those "Windows 
Rules / Linux Sucks" moments).

Comment 1 Natalie Protasevich 2007-07-08 17:24:29 UTC

Vladimir,
Have you tried latest kernels since then?
Thanks.

Comment 2 Vladimir Nicolici 2007-07-09 00:15:26 UTC

I will ask the administration team to attempt a kernel update this week, and I will return with details.

Comment 3 Tejun Heo 2007-08-08 20:48:08 UTC

Ping.

Comment 4 Natalie Protasevich 2008-03-22 23:23:17 UTC

Vladimir, were you able to do some testing with new kernel lately?
