Nice you're talking about the trash bin :) : I was asking myself how to get
access to its content. The documentation only says " Removed files may be
accessed through a separately mounted MFSMETA file system". What does it
mean ?

Fabien

Yes, this is the right part of documentation. At
http://www.moosefs.org/reference-guide.html find: “Removed files may be
accessed through a separately mounted MFSMETA file system” and keep on
reading.  Below there is: “Moving this file to the trash/undel
subdirectory causes restoring of the original file in a proper MooseFS file
system”

« By starting the mfsmount process with the -m (or -o mfsmeta) option
one can mount the auxiliary file system MFSMETA (which may be useful to
restore a file accidentally deleted from the MooseFS volume or to free
some space by removing a file before elapsing the quarantine time), for
example:

mfsmount -m /mnt/mfsmeta »
add -H mfsmaster_host and it works (just tested:)
Hope it helps,

Yes, that's exactly what I was looking for : "-o mfsmeta". It works, I now
can reach the reserved+trash directories, thank you !
