All, We had an indecent yesterday where one of our CES nodes slowed to a crawl. GPFS waiters showed pre fetch threads going after inodes. iohist also showed lots of inode fetching. Then we noticed that the CES host had 5.4 million files open.
The change I made was to set maxStatCache=DEFAULT because it is linux. And set maxFilesToCache=10000000 it was set to 500000. Then restarted GPFS. Is there something else we should change as well.
