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 statAccount: AUTH_8bde12ff804e42498661b7454994c446Containers: 0Objects: 0Bytes: 0X-Put-Timestamp: 1690509333.32481X-Timestamp: 1690509333.32481X-Trans-Id: txcc8962b244bb4ff397885-0064c32014Content-Type: text/plain; charset=utf-8
X-Openstack-Request-Id: txcc8962b244bb4ff397885-0064c32014
[root@controller ~]#

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
