[Gluster-users] Replace faulty host

[Marcus Pedersén]

Hi all,
I have a problem with one of our gluster clusters.

This is the setup:
Volume Name: gds-common
Type: Distributed-Replicate
Volume ID: 42c9fa00-2d57-4a58-b5ae-c98c349cfcb6
Status: Started
Snapshot Count: 26
Number of Bricks: 1 x (2 + 1) = 3
Transport-type: tcp
Bricks:
Brick1: urd-gds-031:/urd-gds/gds-common
Brick2: urd-gds-032:/urd-gds/gds-common
Brick3: urd-gds-030:/urd-gds/gds-common (arbiter)
Options Reconfigured:
cluster.granular-entry-heal: on
storage.fips-mode-rchecksum: on
transport.address-family: inet
performance.client-io-threads: off
features.barrier: disable


The arbiter node has a faulty root disk but it is still
up and glusterd is still running.
I have a spare server equal to the arbiter node,
so my plan is to replace the arbiter host and
then I can calmly reinstall OS and fix the rest of
the configuration on the faulty host to be used
in another cluster.

I want to use the same hostname on the new host.
What is the correct commands and way to replace the aribter node.
I search online and found this:
https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3/html/administration_guide/sect-replacing_hosts
Can I use this guide to replace the host?

Please, give me advice on this.

Many thanks in advance!!

Best regards
Marcus
