Critical Description
Install Couchbase server 6.5.0-2158 on 4 centos 7.5 servers (224, 225, 226, 227).
Create a default bucket on node 224.
Load 1000 docs to default bucket.
On node 227, backup data from node 224 to /tmp/entbackup
On node 226, create default bucket.
On node 227, restore data to node 226
To compare backup data in backup repo and data on restore node, I use forestdb_dump in /opt/couchbase/bin to extract data from backup repo, the extraction failed due to crash on shard_9.fdb
