The problem of cinder-scheduler is okay now 
after forcing the function 

def version_is_compatible(imp_version, version): 
to return True. 

But still the cinder-volume throws error stating that 

2017-06-22 21:27:31.511 10507 ERROR cinder.cmd.volume [req-cae4f97b-e4b1-498e-bb4c-adfa161069d7 - - - - -] Volume service cloud1 at lvm failed to start. 


Thanks,

Hi, 

I have problem in running cinder-scheduler. 

Platform : Ubuntu 16.04.2 LTS 

Pls. find the log of the cinder-scheduler. 

The version of cinder-scheduler is 10.0.0 

I have checked the configuration, none of the errors could 
meet my eyes. 

I googled and find some solution which tweaks few variables, 
but want to carry out preferably with offical patches if any. 

The error is 

2017-06-21 10:20:09.455 2876 ERROR oslo_service.service [req-7f47afcc-49b4-4901-8538-8e943dce23f4 - - - - -] Error starting thread. 


Here is the content of /var/log/cinder/cinder-scheduler.log. 


Thanks,
