synchronous_commit = off
I have a default RBD settings.
Do you have any recommendation?

Hi,
I have an existing few RBDs. I would like to create a new RBD Image for
PostgreSQL. Do you have any suggestions for such use cases? For example;
Currently defaults are:
Object size (4MB) and Stripe Unit (None)
Features: Deep flatten + Layering + Exclusive Lock + Object Map + FastDiff
so much once again for your great help!

Hi,
I also tried:
$ ceph mon ok-to-stop all
No luck again. It seems Ceph ignores this.
Other Ceph cluster which has 9 nodes (and 3 mons) successfully upgraded.

Hi All,
I am trying to upgrade ceph 15.2.1 to 15.2.3. I've two node setup on small
environment for test only. I ran the following commands:
$ ceph mon ok-to-stop mon.vx-rg23-rk65-u43-130
>> quorum should be preserved (vx-rg23-rk65-u43-130,vx-rg23-rk65-u43-130-1)
>>after stopping
upgrade can continue?
If so, Should I upgrade, or wait for 15.2.3 because @Ashley said 15.2.2 has
problems
Thanks,
Gencer.
