I am doing a backup of my sharded cluster in a testing environment and I am having issues getting mongodump to backup my data files.
Steps to produce backup:
1. turn off the balancer on a secondary member of each shard/replicaset.

2. set fsyncLock to false to disable sychronization on each of the secondaries above.

3. connect to two other secondaries in the set and ran mongodump.

However I keep getting this error message, please see file attached.
