Re: FW: Reg:.[CBT] Unable to do a CBT Clean Run.

[Mark Nelson <mnelson@redhat.com>]

Hi Vish,

Thanks for the report!

I seem to remember seeing something very similar to this a while back 
and it turned out to be an issue on the monitor where crushtool wasn't 
in the path.

The way I had to solve it was to set the "crushtool" path via ceph.conf:

https://github.com/ceph/ceph/blob/master/src/common/config_opts.h#L29

Please let me know if that helps.

Thanks,
Mark
