I have a cluster with 2 data nodes. Each index has 5 primary shards and 1
replica. Therefore, the data on both nodes should be identical, at least
for indices that are not changed anymore.
Before I restart/shut a node I disable routing allocation and once the node
is up again I reactivate it.
In most cases the intialization of a shard is really quick as the data is
already there, but sometimes I seems that the whole data is recreated even
though nothing was changed about this index in the meantime.
Is that normal? And how to assure that the existing replica/primary shard
on the rebooted node is reused?
Did I miss something fundamental?
Cheers
Marc
