[lustre-discuss] osc and llite stats files are not exported to clients

[U Sawangwit]

Dear all,

   I am having trouble with lustre monitoring using Ganglia
gmond_python_modules
(https://github.com/ganglia/gmond_python_modules/tree/master/lustre).

    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.

Cheers,
Utane
