Re: PROBLEM: 2.6.6 grinds to a halt with moderate I/O

["Philippe Gramoullé" <philippe.gramoulle@mmania.com>]

Hello Micah,

Could you give more information on the Megaraid part of your setup ?

Are the i/o made on a disk/partition controlled by the megaraid ?

If no, does the same behavior occur on a plain scsi disk ?

If yes, what kind of RAID level do you use ? how many disks ? 

Could you give megaraid firmware information as well as logical volume settings regarding
read,write and cache policy.

Also, is it a regression over previous kernels, like 2.6.5 or even earlier kernels ?

I've been using 2.6.3-mm3 for weeks now with DELL hardware and a megaraid controller
doing intensive i/o around the clock without any problems. The box has been just rock solid.

Thanks,

Philippe
