Once in a while, we run into those pesky, irritating harddisk issues -- out of disk space on one partition, a few fat GBs of disk space on another partition.
Fortunately, there exist a cheap, simple, and neat trick to resolve such an issue on linux. The approach is as follows:
1. Perform the operations using root permissions.
$ su root
2. Do a recursive copy of the folder you want to copy.
Note that we use the -r flag for recrusive copy, and the --preserve flag to preserve important file attributes such as ownership and timestamp.
$ cp -r --preserve=all SOURCE TARGET
3. Delete the source folder
4. Create a symbolic link in place of the source folder.
$ ln -s TARGET DIRECTORY
