Seaweedfs volume management - seaweedfs

Question

I have 2 questions concerning a Seaweedfs cluster we have running. The leader is started with the following command:
/usr/local/bin/weed server -ip=192.168.13.154 -ip.bind=192.168.13.154 -dir=/opt/seaweedfs/volume-1,/opt/seaweedfs/volume-2,/opt/seaweedfs/volume-3 -master.dir=/opt/seaweedfs/master -master.peers=192.168.13.154:9333,192.168.13.155:9333,192.168.13.156:9333 -volume.max=30,30,30 -filer=true -s3=true -metrics.address=192.168.13.84:9091
Question 1
I created a master.toml file using weed scaffold -config=master:
[master.maintenance]
# periodically run these scripts are the same as running them from 'weed shell'
scripts = """
ec.encode -fullPercent=95 -quietFor=1h
ec.rebuild -force
ec.balance -force
volume.balance -force
"""
sleep_minutes = 17 # sleep minutes between each script execution
However the maintenance scripts seem to fail because
shell failed to keep connected to localhost:9333: rpc error: code = Unavailable desc = all SubConns are in TransientFailure, latest connection error: connection error: desc = "transport: Error while dialing dial tcp [::1]:19333: connect: connection refused"
This makes sense since the master is bound to ip 192.168.13.154 and the maintenance script tries to connect to localhost. How can I specificy the master ip in the master.toml file?
Question 2
The amount of volumes seems to grow faster than the amount of disk space used. For example on the .154 server there are only 11 free volumes. But looking at the disk space there should be much more.

],

}
]
}
],
"Free": 16,
"Max": 270,
"layouts": [

]
},
"Version": "30GB 1.44"
}
Disk (192.168.13.154):
/dev/sdb1 1007G 560G 397G 59% /opt/seaweedfs/volume-1
/dev/sdc1 1007G 542G 414G 57% /opt/seaweedfs/volume-2
/dev/sdd1 1007G 398G 559G 42% /opt/seaweedfs/volume-3
Is this related to the maintenance scripts not running properly, or is there something else I'm not understanding correctly?

Answer 1

Question 1: Added a fix https://github.com/chrislusf/seaweedfs/commit/56244fb9a13c75616aa8a9232c62d1b896906e98
Question 2: Likely related to master leadership changes.
