【存储】nas如何挂载swift

1.先明确nas存储盘已经挂到了本机器上

2.利用dd模拟出一个新的空白占位文件。（of写到你挂载的那个目录：这个应该是上面的/srv/node/vdd）

dd if=/dev/zero of=/yfyshare/5T_151.img bs=1G seek=5115 count=0
3.格式化/赋权限/挂载空文件
mkfs.xfs 5T_152.img
mkdir -p /srv/node/sda
chmod 777 /srv/node/sda
vim /etc/fstab
/yfyshare/5T_151.img /srv/node/sda xfs defaults.loop
mount -a
4.之后同理重新构建ring 分发即可。
5.总结nas挂载过来并非完整的裸磁盘，会导致swift无法真正挂载成功，必须dd成占位文件格式化后重新挂载才行。

附上裸磁盘挂载的方式

---shell
#!/bin/sh

ECHO_GREEN() {
    stty erase '^H'
    echo -n -e "\033[32m$1\033[0m"
}

ECHO_GREEN "Please Input DEVICE (example: sdx):  "; read DEVICE
DEVICE_PATH=/dev/${DEVICE}
DEFAULT_NODE_PATH=/srv/node/${DEVICE}
ECHO_GREEN "Please Input NODE (default: ${DEFAULT_NODE_PATH}):  "; read NODE_PATH
NODE_PATH=${NODE_PATH:-${DEFAULT_NODE_PATH}}

echo -e "\n"
echo "    # DEVICE: ${DEVICE}"
echo "    # NODE_PATH: ${NODE_PATH}"
echo "    # fstab: ${DEVICE_PATH} ${NODE_PATH} xfs noatime,nodiratime,nobarrier,logbufs=8 0 2"
echo -e "\n"

ECHO_GREEN '    # VERIFY ? (YES/NO):  '; read VERIFY

[[ ${VERIFY} == 'YES' ]] || [[ ${VERIFY} == 'yes' ]] && \
if [ -b ${DEVICE_PATH} ]; then 
    mkfs.xfs ${DEVICE_PATH}
    mkdir -p ${NODE_PATH}
    echo "${DEVICE_PATH} ${NODE_PATH} xfs noatime,nodiratime,nobarrier,logbufs=8 0 2" >>         /etc/fstab
    mount -a
    chown -R swift:swift ${NODE_PATH}
else
    echo -e "\n Error Device does not exist"
