Hi All, We have been using an elastic search cluster with 3 nodes , running on aws machines , we have been using EBS for work and data directory of elasticsearch . I was experimenting with backup using EBS snapshots , here is what I did 1.) created a snapshot of one ebs volume (say, alpha) 2.) deleted the index 3.) shutdown the cluster 4.) unmounted the ebs volume on alpha (say /mnt/data ) 5.) created a new volume from snapshot and mounted on alpha in the same location (/mnt/data) 6.) restarted elastic search on one node only cluster went to red state , all shards in unassigned state 7.) restarted another node with blank data (/mnt/data ) directory cluster red state , all shards STILL in UNASSIGNED STATE 8.) manually allocated shards to node recovered no documents , few kbs of data got restored ☹ can anyone please help me debug this , what am I doing wrong , is there a better way to do this ?? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
