Hi,
I'm afraid I still need some help.
When I originally set up my gluster (about 3 years ago), I set it up as Distributed-Replicated without specifying a replica count and I believe that defaulted to a replica 2. I have 4 servers with 3 RAIDs attached to each server. This was my result:
Number of Bricks: 6 x 2 = 12 Transport-type: tcp Bricks: Brick1: hydra1:/gluster1/data Brick2: hydra1:/gluster2/data Brick3: hydra1:/gluster3/data Brick4: hydra2:/gluster1/data Brick5: hydra2:/gluster2/data Brick6: hydra2:/gluster3/data Brick7: hydra3:/gluster1/data Brick8: hydra3:/gluster2/data Brick9: hydra3:/gluster3/data Brick10: hydra4:/gluster1/data Brick11: hydra4:/gluster2/data Brick12: hydra4:/gluster3/data
If I understand this correctly I have 6 sub-volumes with Brick2 replica of Brick1, Brick4 of Brick3, etc. Correct ?
I realize now that it would probably have been better to specify a different order, but now I cannot change it.
Now I want to store oVirt images on the Gluster and it requires
either replica 1 or replica 3. I need to be able to reuse the
bricks I have and was planning to remove some bricks, initialize
them and add them back as a replica 3.
Am I supposed to remove 6 bricks, one from each sub-volume ? Will
that work ? Will I lose storage space ? Can I just remove a brick
from each server and use those for the replica 3 ?
Thanks for all the help.
