So /home/andres/tt does not exist, correct? Does this happen for any
attempt to create a new zero-length file using the "touch" command?
(Even in other directories) Can you append to a file using "cat
/etc/mailcap >> some_existing_file"?

If it is "yes" to the first two questions, and "no" the third, it
looks like this might be an inode allocation failure as opposed to a
block allocation failure.

Once this triggers, does it reliably continue to fail if you reboot?
Or does it go away when you reboot?
