I'm assuming that 10.1.11.79 is server A here.
What this _looks_ like is that you deleted the entire
directory here:
cr_dev_shard1_replica2
cr_dev_shard2_replica2
but not
collection1
on server B. This is a little inconsistent, but I think the collection1
core naming was a little weird with the default collection in 4.10...
Anyway, if this is true then there'll be no
core.properties
file in cr_dev_blah blah.
So, Zookeeper has a record of there being
such a thing, but it's not present on your sever B.
To Zookeeper, since the replica hasn't registered
itself it still looks like the machine is just down.
So here's what I'd try:
Well, first I'd back up server As index directories...
Use the Collections API ADDREPLICA command to
add a replica on Server B for each shard, use the "node"
parameter.
That should churn for a while but eventually create a replica
and sync it with the leader. Once that's done, use the DELETEREPLICA
to force Zookeeper to remove the traces of the original replicas on
server B.
Best,
Erick
