Hi, me again.
I think I managed it, anyway, it works, I hope this is the right way to
do it and not a hack. I tried the version using..
setfattr -x trusted.glusterfs.volume-id /bigdisk/brick7/vol-cdimages
setfattr -x trusted.gfid /bigdisk/brick7/vol-cdimages
but this did not work (error message).
Copied from a working server the vol informations to the new servers ...
scp -r /var/lib/glusterd/vols/* sysadmin@nas29:/var/lib/glusterd/vols/
changed the rights on the new server:
chown -R root.root /var/lib/glusterd/vols/*
Then, on the new server:
gluster volume add-brick vol-cdimages nas28:/bigdisk/brick7/vol-cdimages
nas29:/bigdisk/brick8/vol-cdimages nas22:/bigdisk/brick9/vol-cdimages force
--> success.
#gluster volume info vol-cdimages
Volume Name: vol-cdimages
Type: Distributed-Replicate
Volume ID: xxxxxxxxx
Status: Started
Snapshot Count: 0
Number of Bricks: 2 x (2 + 1) = 6
Transport-type: tcp
Bricks:
Brick1: nas20:/bigdisk/brick1/vol-cdimages
Brick2: nas21:/bigdisk/brick2/vol-cdimages
Brick3: nas22:/bigdisk/brick3/vol-cdimages (arbiter)
Brick4: nas28:/bigdisk/brick7/vol-cdimages
Brick5: nas29:/bigdisk/brick8/vol-cdimages
Brick6: nas22:/bigdisk/brick9/vol-cdimages (arbiter)
Hoping this info might be useful for other users.
Regards,
Birgit

Hi Xavi,
Thank you a lot for your response. That's the information I needed.
However, I run actually into an other error message:
root@nas22:# gluster volume add-brick vol-cdimages nas28:/bigdisk/brick7
nas29:/bigdisk/brick8 nas23:/bigdisk/brick9
volume add-brick: failed: Pre Validation failed on nas28. Please check
log file for details.
Pre Validation failed on nas29. Please check log file for details.
The logfile says:

How can I solve this problem?
Kind regards,

Hi list,
I have a replica 3 volume with arbiter.
Now I would like to add a new brick.
How can I do this?
When you expand a volume you need to add as many bricks as necessary
to create a new replica set. In your case you need to add 3 more
bricks (2 data bricks and 1 arbiter) to expand the volume.
You can check the documentation [1] for more information.

gluster volume add-brick ... gives me output:
volume add-brick: failed: Increasing replica count for arbiter
volumes
is not supported.
Thank you for any help.

Birgit
