#
I need to clear up some space in this server to create a different filesystem with the size of 500G.
How do I remove the swap files, and also /lib/libc.so.1?
Also is it possible to shrink the size of / ? How do I do this?
These are the steps I have done to remove /lib/libc.so.1 :
# umount -f /lib/libc.so.1
umount: Operation not supported
umount: cannot unmount /lib/libc.so.1
#
Why do I get this error, and how do I resolve it and of course remove this partition?
These are the steps I have taken to remove swap :
# swap -d /var/run
/var/run: Is a directory
Please help.
