This is to change replication factor in .dat file header. Need to shut down the volume servers

that has those volumes.
|
|
|
|
1. fix the .dat file in place
|
|
// just see the replication setting
|
|
go run change_replication.go -volumeId=9 -dir=/Users/chrislu/Downloads
|
|
Current Volume Replication: 000
|
|
// fix the replication setting
|
|
go run change_replication.go -volumeId=9 -dir=/Users/chrislu/Downloads -replication 001
|
|
Current Volume Replication: 000
|
|
Changing to: 001
|
|
Done.
|
|
|
|
2. copy the fixed .dat and related .idx files to some remote server
|
|
3. restart volume servers or start new volume servers.
