问题描述

安装hosted engine的时候，在最后一步出现下图所示的错误：

[ ERROR ] Error: Fault reason is "Operation Failed". Fault detail is "[Problem while trying to mount target]". HTTP response code is 400.

[ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "Fault reason is \"Operation Failed\". Fault detail is \"[Problem while trying to mount target]\". HTTP response code is 400."}

问题解决

检查nfs的地址，然后重启

mkdir /nfs

chown vdsm:kvm /nfs

vi /etc/exports

增加如下内容：

/nfs  *(rw,sync,no_root_squash)

启动nfs

systemctl restart nfs

systemctl enable nfs

返回到上一步，把Storage Type填写正确
