Resolution:
If any as-agents join / disconnect the cluster gracefully we can view the space redistribution progress from as-admin using the show space "space name" command. It is not possible to view space redistribution progress if sudden seeder drop / kill conditions. Using "verify gmp" you can achieve that.


1). Connect metaspace from as-admin command line.

2). Run the "verify gmp" command.

Sample output while no redistribution happening

==================================================

as-admin> verify gmp

verify gmp:
--------------------------------------------------------------------------------

    Async command sent: verify gmp
--------------------------------------------------------------------------------
Mas-admin> metaspace Layer
  - manager     1
  - member      2
Space Layer

:: seeder_state_none

  - SPACE1,seeder_state_none
    - seeder_state      2
  - SPACE2,seeder_state_none
    - seeder_state      2
  - SPACE3,seeder_state_none
    - seeder_state      2
  - SPACE4,seeder_state_none
    - seeder_state      2

In this case the total seeders are two and the seeder state in none means no redistribution is happening or completed.

In this case the total seeders are 1 and the seeder state in drop means redistribution is in progress due to seeder drop.

In this case total seeders are 2 and the seeder state in join means redistribution is in progress due to a seeder join.
