[SOLVED] Ceph mgr daemon crash - NoOrchestrator exception

[chrispage1]

Hi,

I've suddenly started getting crashes on the active Ceph manager node. It looks to be that the reason is caused by NoOrchestrator. We upgraded to Quincy at the weekend, but have never had any orchestrator modules.

Any idea why this would be happening / how I can stop it from throwing up errors? Strangely this has only occurred twice today, I have never seen the issue before.

Thanks,
Chirs.

Did you configure the NFS manager module in any way?

 

[chrispage1]

I didn't think so but it seems that the NFS module is on:



I don't believe it's needed though. Will disabling this resolve the issue?

 

[mira]

If you don't use it, then yes disabling it should be fine.
Disabling it should get rid of those errors.

Thanks mira, will disable it as it's certainly not needed

Chris.
