I'm glad you were successful. Just for future reference: another cause
of directories that can't be removed is this - I fell into this trap
at work. If you have done a 'chattr +i ....' on any files in the
directory, you won't be able to 'rm -rf' the directory until you have
done 'chattr -i ...' to fix the offending files.

Another fyi. Many have good luck with reiserfs, but all 3 of my
personal attempts to use reiserfs in the past led to fs corruption
after a power failure. Never again in this lifetime.
