I have a situation where I need to replace disks that are failing on a single node in my 4 node Elasticsearch cluster. As a result I'd like to backup the Elasticsearch data on that node only, replace the disks and then restore the data to the new (empty) disks. I've tried shutting down the node in question, but the remaining 3 nodes can only get to a "yellow" state. I'm using 5 primary shards and 1 replica shard per index. I considered using snapshot for the single node, but it seems Elasticsearch does not support snapshot and restore for a single node, it must be done on the whole cluster.
Is it possible to just manually copy the data from the failing disk to another disk, replace the failing disk then copy the data back to the new disk (starting and stopping Elasticsearch before and after this whole process, of course)? -- vic -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
