Description

After upgrading my test environment from infernalis to the latest jewel release candidate last night, I cannot mount cephfs via the kernel client on debian jessie.

Fuse client works without issue and I can read and write files. the kernel client worked on infernalis.

I have separate frontend and backend networks.

more info, I see this pop up on the mon when running in debug mode:

is "peer missing required features" what could cause this? I don't really know where to proceed from here. I'm running debian jessie and have made sure its up to date.

I ran apt-get update and apt-get dist-upgrade, a few updates were installed, but the kernel client still fails.

I'm now on the jewel release 10.2.0 and as noted before, my kernel is 4.3.0-0.bpo.1-amd64

Thanks for your help

OK, so my last update led me to trying a shot in the dark.

running:

ceph osd crush tunables legacy

Allowed me to mount cephfs using the kernel client, but this doesn't exactly give me the "warm-fuzzies" can I consider cephfs to be stable in this sort of config?

I cannot find any guides to upgrade or recompile my cephfs kernel client. Could you please point me in the right direction, so I can be sure that I'm running the current version?

This does result in the following health warning:

health HEALTH_WARN
crush map has straw_calc_version=0

Thanks in advance.

I found a solution I can live with.

I set:

ceph osd crush tunables default

And this works without generating health warnings

The reason this was not set correctly in the first place is because I originally reacted to a health warning after upgrading from infernalis. As a result, I set:

ceph osd crush tunables jewel

Which unknowingly broke compatibility with the kernel client in debian jessie.
