Hi Markus,
It looks quite well documented, but please
use?https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3.5/html/administration_guide/sect-replacing_hosts?as
3.5?is the latest version for RHGS.
If the OS disks are failing, I would have tried?moving the data disks to the new
machine and transferring the gluster files in /etc and /var/lib to the new node.
Any reason to reuse the FQDN ?For me it was always much simpler to remove the
brick, remove the node from TSP, add the new node and then add the brick and
trigger full heal.
Best Regards,Strahil Nikolov?

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
