If you need to check if a volume is mounted in a Bash script, then you can do the following.
How to Check Mounted Volumes
First we need to determine the command that will be able to check.
This can be done with the /proc/mounts path.
How to Check if a Volume is Mounted in Bash
if grep -qs '/mnt/foo ' /proc/mounts; then
echo "It's mounted."
else
echo "It's not mounted."
fi
How to Check if a Volume is Mounted and Available
MNT_DIR=/mnt/foo
df_result=$(timeout 10 df "$MNT_DIR")
[[ $df_result =~ $MNT_DIR ]]
if [ "$BASH_REMATCH" = "$MNT_DIR" ]
then
echo "It's available."
else
echo "It's not available."
fi
Another way of Checking Volume Mounts
mount \
| cut -f 3 -d ' ' \
| grep -q /mnt/foo \
&& echo "mounted" || echo "not mounted"
