I'm trying to add a three datacenter replication using the "join-cluster" command. The mdc_replication.max_targets was set to 3.

The first dc is added without any problem. However, while I'm trying to add the second one, it shows: "Over max number of clusters".

Maybe MaxTargets should be larger than length(Rows) to allow add more replication?

Line 1242 in c1ea685

{ok, Rows} when MaxTargets < length(Rows) ->

-----------------------------------+----------
 [mdcr] max number of joinable DCs | 3
 [mdcr] total replicas per a DC    | 1
 [mdcr] number of successes of R   | 1
 [mdcr] number of successes of W   | 1
 [mdcr] number of successes of D   | 1

cluster id |   dc id    |    status    | # of storages  |          updated at         
-----------+------------+--------------+----------------+-----------------------------

I'm sorry it took me a while to get back to you.
The current version of LeoFS only supports one remote cluster replication.
