Failure of all replication service nodes- AsyncDR

Issue:


After pairing two Elastifile systems for replicating through the AsyncDR feature,

multiple events are fired in the Elastifile UI,

and the replication status changed to failed. 


Explanation:

The issue happens since the replication agent which are used for replicating the data between the systems use external IPs.

The replication agent validate the connectivity with the remote replication agent through the icmp protocol on the external IPs.

By default, this communication is not allowed by the Elastifile FW rules.


Workaround:

Modify the elastifile-ra-service-XXX of both systems.

Add the external IPs of the remote system as source IP in addition to the VPC subnet.
