Break replication context on both source and destination

Command : 

replication break rctx://x

Delete mtree on destination

Command : 

mtree delete /data/col1/<mtree>

Run filesystem cleaning on destination

Command : 

filesys clean start

Note: Run "filesys clean watch" and once cleaning starts at phase 1, you can stop cleaning "filesys clean stop" and make sure mtree is removed by running "Mtree list"

Reconfigure mtree on both source and destination

Command : 

replication add source mtree://<source hostname>/data/col1/<mtree> destination mtree://<destination hostname>/data/col1/<mtree>

Initialize replication context from source

Command : 

replication initalize rctx://x

Make sure replicaiton is initializing successfully

Command : 

replicaton watch rctx://x
