Can not change brick with replace-brick.

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@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@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 J
