Hi,

I'm having an issue with enabling the mgr balancer plugin, properly because a 
misunderstanding in the fundamentals of the crush algorithm. I hope the list 
can help, thanks.

I've enabled the plugin itself and automatic balancing. The mode is set to 
crush-compat and my minimum compatible client is set to jewel.

The mgr daemon throws me the following error: mgr[balancer] Error creating 
compat weight-set

Creating a compat weight set manually with 'ceph osd crush weight-set 
create-compat' gives me: Error EPERM: crush map contains one or more bucket(s) 
that are not straw2

What changes do I need to implement to get the mgr balancer plugin working? 
Thank.

Please let me know if I need to elaborate.

Med venlig hilsen / Best regards
