Another one - "tail -f" doesn't appear to work correctly for logs on
GlusterFS. The logs themselves seem to be OK (not corrupted), but tail
-f doesn't seem to properly list them incrementally, the output ends up
corrupted (missing lines, line breaks, etc). This was observed in the
case where /var/log/glusterfs/glusterfs.log is on glusterfs (AFR). Not
checked whether syslog managed logs suffer the same problem.
