我已经安装了 openstack cinder 模块。一切运行正常。但我想挂载一个卷以查看其内容。
我在 Cinder 存储计算机上输入了 lvscan 命令。我可以看到我的卷列表。
ACTIVE '/dev/cinder-volumes/volume-XXXXX-XXXX-XXXX-XXX-XXXX' [1.00 GiB] inherit
但是当我输入
mount /dev/cinder-volumes/volume-XXXXX-XXXX-XXXX-XXX-XXXX /mnt
我收到此错误信息
mount: wrong fs type, bad option, bad superblock on /dev/mapper/cinder--volumes-volume--XXXXXXXXXXXXXXXX,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so.
是不是因为卷已经被 openstack 实例挂载了？我应该如何挂载或读取/写入此卷中的数据？
以下是 lvdisplay 命令结果：
