创建卷

命令行方式创建

执行如下命令，创建一个卷名为volname1， 用户为userid1，容量为10G的副本卷:

./udbto-cli volume create volname1 userid1 --capacity 10

Create a new volume:
  Name                     : volname1
  Owner                    : userid1
  capacity                 : 10 G

Confirm (yes/no)[yes]: yes
Create volume success.

./udbto-cli volume create --help 可以查看更多的参数选项。

创建好卷后，可以通过如下命令查看卷的详细信息：

./udbto-cli volume info volname1

Resultful方式创建

使用如下命令，创建一个卷名为volume2，用户为userid2，容量为100G的副本卷。volType参数指定为0，创建副本卷; 指定为1, 创建纠删码卷。注意如果不指定卷类型，默认为副本卷。
