Cannot Edit ~/.vimrc file without both E297 error and E667 From Appearing

I am SSHing into an Ubuntu machine where I use Bash as the shell. I used to be able to edit my ~/.vimrc file very easily. Now, whenever I try to write to it, I get a warning

E297 write error in swap file

and also after typing in text, I cannot save the changes. Vim tells me that

E667: Fsync failed. 

In order to exit the file, I simply have to type the :q! (force quit command).

This also happens to my ~/.bashrc file, and any other ~/.file that I access. However, I can successfully edit files in any directory outside of /usr2/.

This is an NFS file system and ls -ld ~ outputs that I have rwx permissions on that directory, and that I am the owner of it:

drwxrwxrwx 9 my_name users ... /usr2/my_name

It is odd because I am the owner of the file and have reading and writing permissions:

ls -l ~/.vimrc
-rwxr----- 1 my_name users 172 Aug 18 14:18 /usr2/my_name/.vimrc

I also have only used 54% of my allotted disk space by my system admin, so it cannot be a disk space issue. I also cannot find any .vimrc.swp files.
