我有这本书：
$ gluster volume status
Status of volume: staging
Gluster process TCP Port RDMA Port Online Pid
------------------------------------------------------------------------------
Brick glfs2:/data/brick1/staging 49155 0 Y 13221
Task Status of Volume staging
-----------------------------------------------------------------------------
There are no active volume tasks
和：
$ gluster volume info
Volume Name: staging
Type: Distribute
Volume ID: 8c290a3f-3616-4c35-b641-6e7b7f79fa06
Status: Started
Number of Bricks: 1
Transport-type: tcp
Bricks:
Brick1: glfs2:/data/brick1/staging
Options Reconfigured:
transport.address-family: inet6
performance.readdir-ahead: on
nfs.disable: on
我想添加一个新服务器来获得复制的 1x2=2 设置。
我这样做了：
$ gluster peer probe glfs1
peer probe: success. Host glfs1 port 24007 already in peer list
$ cd /data/brick1/
$ rsync -aAXHhv --delete --progress staging staging@glfs1:/data/brick1/ --exclude prod/.glusterfs/ --exclude prod/.trashcan/
和这个：
$ gluster volume add-brick staging glfs1:/data/brick1/staging
volume add-brick: failed: Pre Validation failed on 2001:41d0:303:553::. /data/brick1/staging is already part of a volume
我做错了什么 ？
答案1
它看起来像下面的作品：
$ gluster volume add-brick staging replica 2 glfs1:/data/brick1/staging force
