Docker ElasticSearch data directory mount to NFS availability

(Arun) #1


I am using elasticsearch 5.5.1 in docker with 4 nodes(all master) cluster where data directory of all nodes mounted to common host NFS(Network File System).

If NFS mounted drive disconnected from any elasticsearch container host at runtime, Will it create an impact for existing elasticsearch cluster? Container data directory will be able to persist data locally? Will persisted data be consistent across other elasticsearch nodes in cluster where NFS still connected to other nodes?

Later if NFS mount connected back to host running elasticsearch container, will there be data consistent between that particular node and other elasticsearch cluster nodes? Will there be any data loss?
