Mount Points vs Physical Drives

Hi there

i need a way ( some sort of script maybe) to check if a mont point exist when but the physical drive does not

for example if i look in / and see that user_data2 directory exist but there is no user_data2 drive.

another hurdle would be that some of the machines have raided drives so i cannot just check for /dev/sdc to see if it exists

any help would be great thanks

Drives aren't named the same thing as the directories inside them, usually. The disks are device files somewhere under /dev/.

On many UNIX systems, /etc/fstab is a tabular file describing what device files should be mounted on what directories, and /etc/mtab is another tabular file describing what disks are mounted on what directories.

For further details we need to know your system and shell.

sorry i dont think i was clear,
what i am looking for is a way to see if the user_data2 direcoty exist if the dirve does not,
i understand that the drive is not called user_data2, but the issue is that people are running to the direcotry user_data2 and therefore filling up the boot drive

/etc/mtab may help you then, it's usually a table of what devices are mounted on what directories. You can also try df, which should list what files are mounted where along with a little statistics on them.

But, I repeat: If you need more detail than that, we need to know your system, because not all varieties of UNIX and Linux do everything the exact same way.
