[olug] root: permission denied, on reiserfs dir?

[Brian Roberson]

the lsattr util you are using is an ext only util; you have to patch it
(lsattr/chattr) to work with reiserfs extended attribs. -- Next time you
have the issue, try  "fuser {file}" that will propably return a valid pid of
an smbd process that had/has the file open in an exclusive mode ( samba now
enable's kernel op locks by default ) this was probably stopping you from
removing the file, but where able to locally.
