Hello, We have 6 indexes on 5 nodes each shard on a node with no replic. I had a red health on ES today , which appears to be that one shard of one index unassigned due to full disk space, After emptying the server from dummy data. I restarted the node that should have the unassigned node , but it didn't work at All. Then restarted the whole nodes and had 5 shards unassigned. I have on my configurations cluster.routing.allocation.disable\_allocation: true After that we changed the configurations to cluster.routing.allocation.disable\_new\_allocation: true cluster.routing.allocation.disable\_allocation: true cluster.routing.allocation.allow\_primary: true and restarted the whole node. After that the whole shards become unassigned and we discovered that the data on the hard disk is also removed. I want to make sure, what we did wrong so we wont that again. How can I recover unassigned shard for future ? is it by restart ? Dina -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

You had disabled replica? Sorry , then I have no answer. I guess you lost a shard and with the broken shard, the whole index can be gone. It is a known risk you can lose an index if you run out of disk space without having replica on an unaffected node. Shard replica level 1 is active by default for good reason. They are for failsafety, beside query load balancing. Jörg -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
