[Lustre-discuss] Unexplained messages from Lustre in the syslog

[Sébastien Buisson]

Hi there,

We run a cluster with Lustre 1.4.12, and we can see various Lustre 
messages in the syslog for which we did not find any explanation (and 
that are not self explanatory for us :) ).

Here they are:
- "cancel n llog-records failed"
   Jun 15 06:09:53 s_kernel at galibier1 kernel: LustreError: 
23849:0:llog_server.c:432:llog_origin_handle_cancel()) cancel 125 
llog-records failed: -22

- "no handle for file close"

lens 240/2072 ref 0 fl Interpret:/0/0 rc 0/0

We did not notice any Lustre malfunction when the messages appeared, but 
our customer worries about them...
Does anybody know the meaning of these messages?

Thanks in advance.
Sebastien.
