[Gluster-users] Can not change brick with replace-brick.

[Mike Sirius]

Hi guys,

I need to change a server for one brick on two volumes, however I’m getting an error and not sure way.

ubuntu at ip-10-250-154-164:/var/lib$ sudo gluster volume info

Volume Name: gv0
Type: Replicate
Status: Started
Number of Bricks: 2
Transport-type: tcp
Bricks:
Brick1: ec2-46-137-0-188.eu-west-1.compute.amazonaws.com:/export/brick1
Brick2: ec2-46-137-52-99.eu-west-1.compute.amazonaws.com:/export/brick1

Volume Name: gv1
Type: Replicate
Status: Started
Number of Bricks: 2
Transport-type: tcp
Bricks:
Brick1: ec2-46-137-0-188.eu-west-1.compute.amazonaws.com:/export/wp-brick1
Brick2: ec2-46-137-52-99.eu-west-1.compute.amazonaws.com:/export/wp-brick1

~~~

What happened is. The server, which is brick1, got taken down, upgraded and launched again.
Of course after a new launch it got new DNS, everything else the same.

Other servers which are using gluster (have a gluster mount) are fine as well. I have updated /etc/fstab and mounted gluster to new DNS.

However, if I go to one of the gluster servers and do ‘gluster volume info’ I see that brick1 is old DNS (see above).

So, I tried to replace the brick:

ubuntu at ip-10-250-154-164:/var/lib$ sudo gluster volume replace-brick gv0 ec2-46-137-0-188.eu-west-1.compute.amazonaws.com:/export/brick1 ec2-54-228-85-244.eu-west-1.compute.amazonaws.com:/export/brick1 start
brick: ec2-46-137-0-188.eu-west-1.compute.amazonaws.com:/export/brick1 does not exist in volume: gv0

~~

I clearly did not do any typo… totally not sure way is it saying ‘brick does not exists in that volumne’, when volume info shows that brick?

Please help ☺
