Today I had to restart my cluster to change some configuration settings.
I think I did it the right way... following these instructions:
However, after I turned shard allocation back on, the third node in my cluster has only replicas, no primary shards....and the second node has primaries only, no replicas. I know that I am still covered if I have a node failure, but I am confused as to why ES would have reallocated my shards in this manner. This is after 3+ hours of being up...and I have a pretty small dataset:
Total Shards: 348
Unassigned Shards: 0
Uptime: 3 hours
Can anyone shed some light on it for this ES newcomer?
