CEPH Annoying Warning

[apap]

I've managed to get CEPH working. Exciting stuff!


I have this annoying warning constantly present:



I assume it comes from this:



Can I increase the PG of .mgr to 2?



Will it break anything? What is the best practice for this.

Hello,

I would say the error is from your first pool 'Ceph-Pool-1', since it has 120 PGs, which is not a power of 2. Powers of 2 are 1-2-4-8-16-32-64-128-256-512 and so on

I think the .mgr pool is the 'device_health_metrics' pool (but I dunno why it has the name '.mgr'). That one is special and iirc always has only 1 PG.

Kind regards,
Benedikt

I think the .mgr pool is the 'device_health_metrics' pool (but I dunno why it has the name '.mgr')

It got renamed with quincy.

I have this annoying warning constantly present:

Click on the (i) button next to it. This should present you the detailed message and indicate which pool it is. And like @B.Otto already pointed out, it will most likely be the Ceph-Pool-1

This is exactly it. Solved. Thanks!
