Description

When running IOR's writing to our Orion test system, I am seeing many Lustre error messages of the form:

Jan  4 16:24:52 zwicky142 kernel: LustreError: 11-0: an error occurred while communicating with 10.1.1.211@o2ib9. The llog_origin_handle_create operation failed with -2

These are all messages from the clients, with 10.1.1.211 being the address of our MDS.

The clients are running:

$ rpm -qa | grep lustre-modules
lustre-modules-2.1.0-15chaos_2.6.32_220.1chaos.ch5.x86_64.x86_64

And the servers:

# zwicky1 /root > rpm -qa | grep lustre-orion-modules
lustre-orion-modules-2.2.49.50-2chaos_2.6.32_220.2.1.1chaos.ch5.x86_64.x86_64

Yes, please, upload some logs, I agree also that these messages are too noisy and can be avoided if harmless

I haven't checked during mount time, but they are definitely seen during IOR execution itself.

We'll need to get confirmation from Chris, but I think it can be demoted from a blocker since they don't appear to be reaching the application and causing failures.

As far as I can tell, they are relatively harmless, although it does muddy the syslog messages quite a bit. If these messages can be safely ignored, they shouldn't make it to syslog at all IMO.

I can upload the client syslog info if it's helpful..?

[Mikhail Pershin]

are these messages seen upon client mount or during IOR itself? This can be harmless messages, related to sptlrpc llog. Is there some log (syslog or console) from any client?

This bug is set as blocker, are these messages affecting IOR execution somehow?

[Peter Jones]

No problem. I have moved it to the Orion project.

[Prakash Surya (Inactive)]

Yeah, sorry, it probably should have been an ORI ticket. It was too late to fix by the time I realized it was an LU.

[Peter Jones]

Should this ticket have been opened under the ORI project rather than the LU project?

Blocker for ORI on Sequoia.
