SeaweedFs: how to set max size for each volume?

Question

When I start the master service I can specify the maximum volume size with the parameter -volumeSizeLimitMB.

./weed master -mdir="." -volumeSizeLimitMB=1000.

Then, I start two volume services.

./weed volume -mserver="localhost:9333" -dir="." -max=10

./weed volume -mserver="localhost:9333" -dir="." -max=10 -port=8081

I have some questions:

1. How can I specify the maximum volume size when I start the volume service? Does it know it straight away because the master service communicate this to the volume service when it connects? I understand max is for the max. number of volumes, but how about the size of each single volume?

2. The master creates volume 8 and 11 on one volume service and 9 and 10 on the other, then it states "No space left". I don't understand why. Here is the whole log: https://pastebin.com/cLRd8gvt

Answer 1

1. The master controls which volume is writable. When it reaches the volumeSizeLimitMB, no writes will be sent over to the volume servers. So the volume server does not need to know the volumeSizeLimitMB.
