Hi,
it's correct that both read and write I/O is paused when a pool's
min_size is not met.

Hi,
Could you tell me whether read I/O is acxepted when the number of replicas
is under pool's min_size?
I read the official document and found that there is a difference of the
effect of pool's
min_size between pool's document and the pool's configuration document.
Pool's document:
https://docs.ceph.com/en/latest/rados/operations/pools/
To set a minimum number of required replicas for I/O, you should use the
min_size setting.
Pool's configuration document.
https://docs.ceph.com/en/latest/rados/configuration/pool-pg-config-ref/
osd pool default min size
Description
Sets the minimum number of written replicas for objects in the pool in
order to acknowledge a write operation to the client.
The former says that min_size is related to both read/write I/O.
On the other hands, the latter says it's only about write I/O. So which is
correct description?
As a result of my verification, the former looks correct.
I created a RGW object in a pool having 3 replicas and its min_size is 2.
Both read and write aren't accepted when 2 replicas are gone.
Thanks,
Satoru
