[Gluster-users] glusterfs missing files on ls

Also directories got removed. I did a really bad job in that script, wrong
sed and path was not truncated and replaced with the fuse mountpoint...
Yes I can move to 3.3.2qa3. At the moment I have gluster installed as per
the semiosis repository. What is the best way for me to move to this other
version (I think that I have to build it from source?)?

Thanks and best regards,
