[gpfsug-discuss] CES log files

[Christof Schmitt]

A winbindd process taking up 100% could be caused by the problem 
documented in https://bugzilla.samba.org/show_bug.cgi?id=12105

Capturing a brief strace of the affected process and reporting that 
through a PMR would be helpful to debug this problem and provide a fix.

To answer the wider question: Log files are kept in /var/adm/ras/. In case 
more detailed traces are required, use the mmprotocoltrace command.

Thanks. Some of the node would just say “failed” or “degraded” with the 
DCs offline. Of those that thought they were happy to host a CES IP 
address, they did not respond and winbindd process would take up 100% CPU 
as seen through top with no users on it.
 
Interesting that even though all CES nodes had the same configuration, 
three of them never had a problem at all.
 
JF – I’ll look at the protocol tracing next time this happens. It’s a rare 
thing that three DCs go offline at once but even so there should have been 
enough resiliency to cope.
 
Thanks
Richard

mmhealth might be a good place to start
 
CES should probably throw a message along the lines of the following:
 
mmhealth shows something is wrong with AD server:
...
CES                      DEGRADED                 ads_down 
...

Which files do I need to look in to determine what’s happening with CES… 
supposing for example a load of domain controllers were shut down and CES 
had no clue how to handle this and stopped working until the DCs were 
switched back on again.
 
Mmfs.log.latest said everything was fine btw.
 
Thanks
Richard
