XenServer之XenServer 7 上创建本地ISO库
时间:2022-06-30 20:50:26 编辑:袖梨 来源:一聚教程网
今天在XenServer7 上想创建个ISO库,但是发现出现一个之前没有过的问题,症状如下
[root@DS-Server04 ~]# lvcreate -L 20G -n local_iso `vgs|awk 'NR==2{print $1}'`
lvcreate -L 20G -n local_iso VG_XenStorage-8e812398-6d55-b06a-2907-ac95c4c12533: Command not permitted while global/metadata_read_only is set.
居然提示全局只读 命令不允许。经过gg的查找最后在思杰官方找到了解决方法
[root@DS-Server04 ~]# pvs

这是一台刚装好系统的XenServer 7,
[root@DS-Server04 ~]# lvcreate -L 20G -n local_iso `vgs|awk 'NR==2{print $1}'` --config global{metadata_read_only=0}
Logical volume "local_iso" created.

下载个镜像看看
