No, we don't store the information separately. But it can be easily predictable from the Volume Info.

For example, in the below Volume info, it shows "Number of Bricks" in the following format,

    Number of Subvols x (Number of Data bricks + Number of Redundancy bricks) = Total Bricks

Note: Sub volumes are predictable without storing it as separate info since we do not have a concept to mix different sub volumes types for single Volume(Except in case of Tiering).  But in future we may support sub volumes with multiple types within a Volume.(Issue with Glusterd2 https://github.com/gluster/glusterd2/issues/388)

First 6 bricks belong to First sub volume and next 6 bricks belong to second.

Hi Team,

Please let me know how I can know which bricks are part of which sub-volumes in case of disperse volume, for example in below volume has two sub-volumes :
Type: Distributed-Disperse
Volume ID: 6dc8ced8-27aa-4481-bfe8-057133c31d0b
Status: Started
Snapshot Count: 0
Number of Bricks: 2 x (4 + 2) = 12
Transport-type: tcp
Bricks:
Brick1: pdchyperscale1sds:/ws/disk1/ws_brick
Brick2: pdchyperscale2sds:/ws/disk1/ws_brick
Brick3: pdchyperscale3sds:/ws/disk1/ws_brick
Brick4: pdchyperscale1sds:/ws/disk2/ws_brick
Brick5: pdchyperscale2sds:/ws/disk2/ws_brick
Brick6: pdchyperscale3sds:/ws/disk2/ws_brick
Brick7: pdchyperscale1sds:/ws/disk3/ws_brick
Brick8: pdchyperscale2sds:/ws/disk3/ws_brick
Brick9: pdchyperscale3sds:/ws/disk3/ws_brick
Brick10: pdchyperscale1sds:/ws/disk4/ws_brick
Brick11: pdchyperscale2sds:/ws/disk4/ws_brick
Brick12: pdchyperscale3sds:/ws/disk4/ws_brick

Please suggest how to know which bricks are part of first and second sub-volume.

Thanks and Regards,
