Hello guys, I am doing some research here about ocfs2, I suppose it has a very bad impact on device waiting. could you please perform the following command and reply with your output? this request goes out only to linux 2.6 (2.6.18 prefered) users. the comand is: iostat -x my output of the ocfs2 partition is: Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s avgrq-sz avgqu-sz await svctm %util sdc 89.30 17.81 54.28 2.24 1146.82 156.96 23.07 0.59 10.44 6.07 34.29 it is a 2-4K block-cluster size (can't remember which one exactly) ocfs2 partition of a shared iscsi device connected via iscsi hba. I have many folders and many many subfolders, the structure is like albums/1/5/7/34157/image.jpg and as you can see the average utilization is 34%. at peak times it goes up to 70%. you might ask how do I know that, since "iostat -x" shows average data since restart - the answer is simple, I restarted several hours ago and it is the lowest load of the day time right now. I need to see your info to check if my clues are correct. Best regards, Arkadiy mailto:eth@ethaniel.com
