Re: [External] Slot issues

I guess max_replication_slots has to >  current total slots in use. (and not >= ) 

https://www.postgresql.org/docs/10/static/runtime-config-replication.html

https://github.com/postgres/postgres/blob/d6e98ebe375e115c29028f9bd090f0f7e07e2527/src/backend/replication/slot.c#L1506

from the doc, it says defaults are 10, any reason why you have set it to 2. You need to set it at a value higher than number of slots active. 

also, i guess changing this parameter would require a server restart.

Hi Team,

I am getting this ERROR while starting my second slave server 

 

PANIC:  too many replication slots active before shutdown

HINT:  Increase max_replication_slots and try again.

max_replication_slots on my master is 2 and one of them is already active for another slave,

do i need to increase this parameter for the need of working of another slave ? if so whats the reason ?

Thanks
