How to change mountpoint name?

Question

I am working in ubuntu, this is what df -h shows: ``` Filesystem Size Used Avail Use% Mounted on /dev/vda 30G 1.7G 27G 6% / none 4.0K 0 4.0K 0% /sys/fs/cgroup udev 15G 12K 15G 1% /dev tmpfs 3.0G 372K 3.0G 1% /run none 5.0M 0 5.0M 0% /run/lock none 15G 0 15G 0% /run/shm none 100M 0 100M 0% /run/user /dev/vdb 197G 60M 187G 1% /mnt ``` Now I want to change the name of `/mnt` to `/data` directory instead. I want all the content to stay where it is, the only thing that has to change is the name of the drive mountpoint. Here is what I have in `/etc/fstab` file. ``` LABEL=c3image-rootfs / ext4 errors=remount-ro 0 1 /dev/vdb /mnt auto defaults,nobootwait,comment=cloudconfig 0 2 ``` Could you please explain the commands necessary and the files to edit?

Accepted Answer

It goes without saying that you should be careful, and understand what each command does before running it - you might also need to make sure that nothing is using the files while you do this.

Make the new mountpoint

```
mkdir /data
```

unmount the current mountpoint

```
umount /mnt
```

edit /etc/fstab and change `/mnt` to `/data`

```
/dev/vdb        /data    auto    defaults,nobootwait,comment=cloudconfig 0       2
```

mount the new location

```
mount /data
```

It is not recommended to remove the /mnt directory because in part of Linux standard system tree, but you can remove the old mount point, named for example /old/mnt/path with this command:

```
rmdir /old/mnt/path
```

because a mount points is a directory.
