I have a 4 node cluster. (just a proof of concept right now, but will
potentially consume 100gb+ per day)
What configuration items do I need to learn/read about to delay
re-balancing of unallocated shards? For example, I am required to do system
patching on a regular basis, so each node is going to have to go through a
reboot. How can I reboot the host, or restart ES for new settings to take
effect, without kicking off the re-balance?
Can I somehow specify a delay? My current config is posted below.
ALSO: I notice (in the head plugin) if I do a "service elasticsearch
restart" on a node that I will end up with two nodes with the same address
each holding different shards, probably because in the short time the node
was down that particular shard wasn't moved somewhere else. Is this OK? For
example, if i restart LouDvEs001 (which is the address, names are auto gen)
I'll have two nodes with different names, but the same address.
