[SOLVED] CEPH version

[morfair]

What is version of CEPH kernel modules in 4.4.16-1-pve? How to see it?

What CEPH's CRUSH map tunables I can use?

 

[fabian]

that's not the current PVE kernel
we use the module code from 4.4 (+ whatever patches Ubuntu applies on top)

My last update was about two months ago. This kernel was in this update. It kernel >4.4.
I want to know, what can I set ceph osd crush tunables profile (http://docs.ceph.com/docs/jewel/rados/operations/crush-map/#tunables)?

 

[fabian]

updating only every two months is not a good idea (for any publicly reachable system running anything)

your question is answered in the ceph documentation:

Our upgrade policy depends on the possibility of downtime.
