why my indexer is not added into cluster ?

[ramarcsight]

Hello everyone
I restarted a indexer IDX1 which is already in a cluster .
So after restarting IDX1 i see this error in CLusterMAster

CLUSTER_ADD_PEER_FAILED__guid=123456-434-4Ty-ABC-6373637 server name=SQL01 ip=1.1.1.1:8089_bucket already added as clustered, peer attempted to add again as standalone. guid=123456-434-4Ty-ABC-6373637 bid= coral_data~

In cluster master under settings-indexer clustering--Peers ---

SQL01 status=down
and on the IDX1 side i see this error -- under indexer clustering

Slave is unable to handle request at this time. This means either slave unable to communicate w/ master OR master does not have peers added to the cluster. Check master dashboard and/or master_uri/secret settings."

Hi @ramarcsight,

Looks like one of the buckets are causing the issue. Please refer to the second answer from https://answers.splunk.com/answers/115905/unable-to-add-cluster-peer-back-to-cluster-master-get-erro... and see if it works for you

It's a production env , is there any way I can replicate this problem in test env ??

It might be one-off issue. Did you manage to fix?

unmouted the /opt and mounted it again
