Comments

This is fixed along with 'dcache scalability support' patch under LU-506.

Minor note - as part of this bug, please quiet the noisy console message for -ENOENT error:

ll_inode_revalidate_fini()) failure -2 inode 144115205255726661

[Sarah Liu]

The duration defined in racer.sh is 900s, it took about 40 minutes for all dd processes ended, and the result.yml file was not completed. I am not sure if it's the script's problem.

[Lai Siyao]

Sarah, what failure did you get? The console log reported several soft lockup (on different 'ls' processes), but this may be reasonable because lock contention can be heavy in racer test.

[Sarah Liu]

I applied the above patch and run racer again, got another failure, please find the console log in the attached.

Oleg thinks that this is related to the http://review.whamcloud.com/#change,2491 fix
