Changing Linux Mount Points
If you’re familiar with UNIX, you know that changing mount points is really pretty easy. All you have to do is go into “/etc/fstab”, “/etc/vfstab” (or whatever your flavor of UNIX happens to call its filesystem table) and change the mount directory.
If, for instance, you had a Solaris box, and you wanted to make the disk currently mounted as “/data” be mounted as “/database”, all you would have to do is the following:
# umount /data
# mv /data /database
Change this line in “/etc/vfstab” from something like this:
/dev/dsk/c1d0s6 /dev/rdsk/c1d0s6 /data ufs 1 yes -
to something like this:
/dev/dsk/c1d0s6 /dev/rdsk/c1d0s6 /database ufs 1 yes -
and remount it as “/database”.
# mount /database
With Linux, however, it’s not quite so clear anymore… It’s still easy, but it’s just not so clear what you have to do since they have now taken to mounting filesystems using the volume label. Rather than pointing directly to the disk device, Linux points to the label, and “/etc/fstab” look more like this:
LABEL=/data /data ext3 defaults 1 2
You can always simply change the disk label, but if you don’t care, you can just tell linux where the raw device is, bypassing the need to worry about the label. The easiest way to do this is simply to replace the “LABEL=/data” value to the “/dev” entry of the disk itself. Then, simply change “/data” to “/database” and you’re all set.
Here is an example of what you would do to change the mountpoint of “/data” to /database”:
# umount /data
# mv /data /database
Change this line in “/etc/fstab” from this:
LABEL=/data /data ext3 defaults 1 2
to this:
/dev/sda6 /database ext3 defaults 1 2
and remount it as /database
# mount /database
Remembering to change the example values here with those required for your situation.

[...] Labels are, of course, arbitrary, so there is no technical need to do this, and you could, instead simply change the mount point in the fstab file, mounting the partition by device name rather than label, but it is usually cleaner to change the label. Here is how you do it: [...]
Is there an easy way to export the same fstab file to multiple machines? I’d like to find a way to easily change the mount points so everyone in our group will have the same.
Thanks.
