Lustre is transitionning /proc files to /sys per kernel developer requests.
Instead of chasing where these files are located now depending on your Lustre version, 'lctl get_param' is the official way to read them. This command will figure out where to properly read the files.

Upon closer inspections, I found that the stats files in /proc/fs/lustre/osc/*/ and /proc/fs/lustre/llite are missing (among other similar files in these directories). However, lctl get_param osc.*.stats and lctl get_param llite.*.stats return parameters and values as you would expect. The stats files are what the gmond_python_modules wants hence the problem monitoring with Ganglia. After many searching around, could not figure out what I could have done to have stats export normally to clients and remounting did not help. On MDS and OSS, I can see the obdfiler/*/export/*/stats or mdt/*/export/*/stats The lustre manual also said that the exporting of these info to client should be by default. Thank you in advance.
