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
After that we changed the configurations to
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 ?
