Hi @Ayus

Simplivity use Postgres DB to store internal component information . If Arbiter has already been installed and working so we can get the IP of Arbiter where it is installed.

Steps:

1. Login to one of the OVC using administrator account like administrator@vsphere.local .

2. Type below commands

#sudo su

#source /var/tmp/build/bin/appsetup

# psql -xc "SELECT * from storage_cluster;" | grep -i arbiter_address

3. Above query will fetch the Arbiter IP address. ( arbiter_address | XXX.XXX.XXX.XXX ).

Hope it helps.

Jaipal

Hi @Ayus

Arbiter is very critical for tie breaker and Quorum calcuation. Yes, you can uninstall the Arbiter from machine which is not being used as Arbiter server.

1. Login to any of the OVC and run below commands

#sudo su
#source /var/tmp/build/bin/appsetup
#grep -i 'Arbiter has address' $SVTLOG

It will bring up active Arbiter IP and Arbiter ID from logs.
2024-03-19T12:50:16.324Z INFO 0x7f7ab6d5b700 [:] [control.arb.arbiterdiscovery] arbiterdiscovery.cpp:402 Arbiter has address XX.XX.XXX.XXX, discoveredId=XXXXXXX-XXXX-XXXX-XXXX-XXXXXXXX

2. Now run below query:

psql -xc "SELECT * from storage_cluster;" | egrep -i 'arbiter_id|arbiter_address'

3. Above query will get all the Arbiter IP and Arbiter ID. You will have keep the Arbiter which matches with logs and in DB and another can be safely removed.

If you face any difficulty, please feel free to log a support case.

Hope it helps.
