解决办法

实际上是因为脚本里面设置的是临时挂载，重启后会失效，只需要重新挂载即可

在swift-compute脚本里面查看脚本内容

.....
echo "/dev/$OBJECT_DISK /swift/node xfs loop,noatime,nodiratime,nobarrier,logbufs=8 0 0" >> /etc/fstab
mkdir -p /swift/node/$OBJECT_DISK
mount /dev/$OBJECT_DISK /swift/node/$OBJECT_DISK
scp $HOST_NAME:/etc/swift/*.ring.gz /etc/swift/
.......

计算节点从新挂载生效

[root@compute ~]# umount /swift/node/
[root@compute ~]# source /etc/openstack/openrc.sh
[root@compute ~]# mount /dev/$OBJECT_DISK /swift/node/$OBJECT_DISK
[root@compute ~]# lsblk

控制节点验证

[root@controller ~]# source /etc/keystone/admin-openrc.sh
[root@controller ~]# swift stat
               Account: AUTH_8bde12ff804e42498661b7454994c446

还有一个办法就是直接弄成永久挂载，这样即使重启也没事
