Gluster users - Oct 2019 - distributed replicated volume - added bricks

Hi Herb,

First check your data usage, as you need free space on the remaining bricks. You
have to remove bricks multiple per replica set.
For replica 2 distributed volume you must specify 2 bricks at least , or any
number multiple by 2 (2,4,6,8 bricks).

The removal consists of several actions .

1. Starting removal via :

gluster volume remove-brick <VOLNAME> <BRICKNAME> start

This actually only migrates  the data to the  rest of the bricks.

2. Check status  via:

gluster volume remove-brick <VOLNAME> <BRICKNAME> status

Once completed, check the logs for any rebalance  issuues.

You can verify data/inode count on the brick via:

gluster volume status <VOLNAME> detail


If everything is fine proceed with the actual removal:

# gluster volume remove-brick <VOLNAME> <BRICKNAME> commit


5. Last verify the volume status.

out of the volume.? However, is it as simple as pulling them out and the data
will rebalance to the disks that are left?
