I have an ancient server with SLES 10 SP2, I want to change an attribute of file to immutable, I know that I need to do chattr +i <file>
. But it does not seems to be working, the file attributes is not changed. And I'm out of my wits now. Where can I look to fix this problem?
Here's a screenshot of my problem.
P.S. e2fsprogs version is 1.38
