The second question, is it any cache tier mode, that replica can be set on
1, for best use of SSD space?

Hello,
It is safe to rename pool with cache-tier? I want to make some
standardization in pools name for example pools 'prod01' and 'cache-prod01'.
Maybe before rename should I remove cache tier?

Can someone help? Any ideas? It is normal that whole cluster stops at disk
full error on cache tier, I was thinking that only one of pools can stops
and other without cache tier should still work.

Hi,
It is possible to reduce pg_num at not used pool, for example from data or
mds. We are using only rbd pool, but pg_num for data and mds is set to 1024.

Hi thanks for reply.
From the top of my head, it is recommended to use 3 mons in
production. Also, for the 22 osds your number of PGs look a bug low,
you should look at that.
