Hello together,
we have a 3 node SH-Cluster where one member is not getting up again.
If we want to restart the Splunk daemon it will stuck on the very last task to start the web server.
After a while we are getting a WARNING: web interface does not seem to be available!
On the newly selected captain node I've checked the kv status for the specific host:
configVersion : -1
hostAndPort : <ip>:8191
lastHeartbeat : Mon Apr 15 ....
lastHeartbeatRecv : ZERO_TIME
lastHeartbeatRecvSec: 0
.
.
.
replicationStatus : Down
uptime : 0
When I search for error logs in the _internal logs I can see following messages in mongod logs:
REPL [ReplicationExecutor] Error in heartbeat request to <own-ip-address>.8191; HostUnreachable: Connection refused
ASIO [NetworkInterfaceASIO-Replication-0] Failed to connect to <own-ip-address>:8191 - HostUnreachable: Connection refused
Should this ip address be the address of the captain?
splunkd logs doesn't indicate any errors.
For me it seems like the syncronisation of the kv store doesn't work.
I've tried this already, but it didn't help:
https://docs.splunk.com/Documentation/Splunk/6.5.2/Admin/ResyncKVstore
any suggestions? Thanks!
You can run splunk clean raft
on the affected member only, too. See if that helps.
Your two other members are working fine? What are the outputs of splunk show shcluster-status
and splunk show kvstore-status
on the working members/captain?
In case that only one member is going crazy, I'd suggest simply removing it from the cluster and adding it again after cleaning it if splunk clean raft
didn't do the job.

can I execute the command in the section "fixing the entire cluster" of this link without being worried to break the other nodes of the cluster?:
https://docs.splunk.com/Documentation/Splunk/6.5.2/DistSearch/Handleraftissues#Fix_the_entire_cluste...
Any experience with that?
