Description

Some CERROR(...) or CWARN() messages clutter up the syslog and should be changed to CDEBUG(D_*, ...). This bug is specifically for 2.x messages.

Ideally, it should be possible to mount then unmount Lustre under normal usage without getting a screen full of messages.

Simply turning off all of the messages is NOT an acceptable solution for all cases.

Looking at the 2.x mount messages from https://maloo.whamcloud.com/test_logs/cc6b7bee-92e8-11e0-a0d3-52540025f9af:

Lustre: Lustre LU module (ffffffffa0495460).

Lustre: Lustre OSC module (ffffffffa075b720).

Lustre: Lustre LOV module (ffffffffa07c8220).

Lustre: Lustre client module (ffffffffa0878980).

These should all just be turned off, since they provide very little useful information.

libcfs_debug_str2mask()) You are trying to use a numerical value for the mask - this will be deprecated in a future release.

This one is already being fixed in LU-314.

Lustre: 28105:0:(sec.c:1474:sptlrpc_import_sec_adapt()) import MGC10.2.34.111@o2ib->MGC10.2.34.111@o2ib_0 netid 5000

0: select flavor null

Should not be printed to the console if flavor == null, and should be changed to LCONSOLE_INFO to make message cleaner.
