Neo4j Causal Cluster "No space left on device, Database unavailable"


We have a Neo4j Causal Cluster with 3 nodes. Each node has a 20G disk partition designated for Neo4j to use.

After upgrading from 3.5 to 4.2, we tried to import data into the Cluster without success. The data to be imported is about 2-3Gb in total.

The error is:
org.neo4j.internal.kernel.api.exceptions.TransactionFailureException: org.neo4j.kernel.availability.UnavailableException: Timeout waiting for database to become available and allow new transactions. Waited 10s. 2 reasons for blocking: Clustering components have encountered a critical error: No space left on device, Database unavailable.


If any details are missing please just ask


the above would appear to suggest that you have a full file system? Has this been validated/confirmed?
