Can you share your cluster setup?

  1. Number of Zeros and commands used to run Zero.
  2. Number of Alphas and commonds used to run Alpha.
  3. du output for the size of p, w, and zw directories for each instance.

The directory sizes do not need to exactly match between the replicas, but you can expect them to be roughly the same.

hi.
This is my cluster config

On SERVER1

dgraph zero --my=SERVER1:5080 --replicas 3 --idx 1 --bindall=true --wal /var/run/dgraph/zw
dgraph alpha --my=SERVER1:7080 --lru_mb=10000 --zero=SERVER1:5080 ----badger.vlog=disk  -p /var/run/dgraph/p -w /var/run/dgraph/w

On SERVER2

dgraph zero -o 1 --my=SERVER2:5081 --replicas 3 --peer SERVER1:5080 --bindall=true --idx 2  --wal /var/run/dgraph/zw
dgraph alpha --my=SERVER2:7081 --lru_mb=10000 --zero=SERVER1:5080 -o 1 --badger.vlog=disk  -p /var/run/dgraph/p -w /var/run/dgraph/w

On SERVER3

dgraph zero -o 2 --my=SERVER3:5082 --replicas 3 --peer SERVER1:5080 --bindall=true --idx 3 --wal /var/run/dgraph/zw
dgraph alpha --my=SERVER3:7082 --lru_mb=10000 --zero=SERVER1:5080 -o 2 --badger.vlog=disk  -p /var/run/dgraph/p -w /var/run/dgraph/w

I have 3 zero, 3 alpha.
This is output folder:
