BASH - 检查是否在没有 AWS CLI 工具的情况下将卷附加到实例
BASH - Check if a volume is attached to instance without AWS CLI tools
我正在编写一个脚本,该脚本需要检查卷是否附加到实例 (/dev/sdf)。
我尝试以两种方式进行,但它一直告诉我该卷没有附加,即使它是附加的。
这是我的第一次尝试:
if test -d /dev/xvdf; then
echo "Volume is attached!"
else
echo "Volume is not attached! Please attach it first, then re-run this script!"
exit 1
fi
这是我的第二次尝试:
if grep '/dev/xvdf' /etc/mtab > /dev/null 2>&1; then
echo "Volume is attached!"
else
echo "Volume is not attached!"
exit 1
fi
这里是 lsblk
输出的卷已附加证明:
ubuntu@ip-10-XX-X-XX:~$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
xvda 202:0 0 8G 0 disk
└─xvda1 202:1 0 8G 0 part /
xvdf 202:80 0 100G 0 disk
非常感谢任何帮助!
好吧,我想出了一个解决方案(不是最漂亮的解决方案,但它有效)
vol='/dev/xvdf'
volcheck=`ls /dev/xvdf`
if [ $volcheck = $vol ]; then
echo "Volume is attached!"
else
echo "Volume isn't attached!"
fi
这也有效:
if test -b /dev/xvdf; then
echo "Volume is attached!"
else
echo "Volume is not attached! Please attach it first, then re-run this script!"
fi
