If you try to delete a directory over NFS and get an error such as...
rm: cannot remove directory 'asdf/': File exists... you will notice that conventional methods won't be good enough to remove it.
$ chmod -R 777 asdf/ $ rm -rf asdf/ $ rm: cannot remove directory 'asdf/': File existsUsually there is a file like .nfs234B inside the directory than can be displayed with ls -la Removing this file only replaces it with another. There are two solutions: manually delete the file on the NFS server, or (if you don't have that type of access) kill its process.
$fuser -u asdf/.* asdf/.: 9070c(user) asdf/..: 28690c(user) 24845c(user) asdf/.nfs934B: 9070tm(user)9070 is the offending process. Kill it with fire.
$ kill -9 9070Should be able to remove that directory now.
