Hi Ashley,
Thanks for your response. Nothing that I can think of would have
happened. We are using max_mds =1. We do have 4 so used to have 3
standby. Within minutes they all crash.

Hi Paul,
I appreciate the response but as I'm fairly new to Ceph, I am not sure that
I'm understanding.
Are you saying that you believe the issue to be due to the number of open
files? If so, what are you suggesting as the solution?
Thanks.

I should clarify this a little bit: you shouldn't touch the CephFS internal
state or data structures unless you know
Understood Paul, thanks.
In case this helps to shed any further light...Digging through logs I'm
also seeing this:

Thanks Everyone,
I was able to address the issue at least temporarily. The filesystem and
MDSes are for the time staying online and the pgs are being remapped.
What i'm not sure about is the best tuning for MDS given our use case, nor
am i sure of exactly what caused the OSD to flap as they did,
Marco,
Could you please share what was done to make your cluster stable again?
