We are using version 6.5.2, I discovered something similar. Our searchheads were showing an error: Failed to add peer 'guid=B193F763-99BC-41B5-89D0-CDEF1F1BF36E server name=splunkindexer14 ip=192.168.12.24:8089' to the master.
Error=bucket already added as clustered, peer attempted to add again as standalone. guid=B193F763-99BC-41B5-89D0-CDEF1F1BF36E bid= myindex~38~B193F763-99BC-41B5-89D0-CDEF1F1BF36E
) To fix this I needed to find the bucket:
Log into the indexer, become splunk, get in the path of the offending bucket and find it.
$> su - splunk
$> cd /x/x1/db/<index>
$> ls -lh
2) The problem bucket will stand out like a sore thumb and be easy to spot because its name will be shorter than all the others.
Actual standalone bucket that caused the problem: db_1487878740_1487878740_38
3) Rename it using move as shown below, adding the CM GUID: (leaving out the double quotes)
$> mv “db_1487878740_1487878740_38” “db_1487878740_1487878740_38_B193F763-99BC-41B5-89D0-CDEF1F1BF36E”
4) Now do list again ( “ls | grep ” ) and verify you were successful, you should see the renamed bucket:
$> ls | grep db_1487878740_1487878740_38
db_1487878740_1487878740_38_B193F763-99BC-41B5-89D0-CDEF1F1BF36E
5) Reboot the indexer
Many thanks Rajpal!
