Hi,
If your clients can support the firefly tunable you can set firefly:
'ceph osd crush tunables firefly'
Or you can hide the warning:
mon warn on legacy crush tunables = false in [mon] section in ceph.conf.
Thanks

Thanks, Can I ignore this warning then?
health HEALTH_WARN
crush map has legacy tunables (require bobtail, min is firefly)

Hi,
Take a look at the docs here (
http://docs.ceph.com/docs/jewel/rados/operations/crush-map/#tunables) for
details on what tunables work with which kernel version. and how you can
change them e.g:
'ceph osd crush tunables bobtail'
You could use a main line kernel from here (http://elrepo.org/t
Hi Sean,
Thanks for the quick response, this is what I see in dimes:
set mismatch, my 102b84a842a42 < server's 40102b84a842a42, missing
400
How can I set the tunable low enough? And what does that mean for performance?
Cheers,
Mike

Hi,
It should work for you with kernel 3.10 as long as turntables are set low
enough - Do you see anything in 'dmesg'?
Thanks

Hi All,
Is mounting rbd only really supported in Ubuntu? All of our servers are CentOS
7 or RedHat 7 and since they are at Kernel 3.10, I can’t get rbd working. Even
if I use legacy tunables or set tunables to 1/2/3… Nothing will mount the block
device.
The only answer I can find to get this
