[MooseFS-Users] rsync from moosfs chnages source file time stamps

[Valeri G. <ga...@ki...>]

Dear Experts,

I have sort of weirdness I just stumbled over.

I migrates some directories to moosefs (free opes source version, standard
installation "by the book" on FreeBSD). At some point I decided to migrate
the directory back to local (UFS) filesystem on the machine. Here is
weirdness I observe:

after i run

rsync -avu /path/do/mfs/mount/directory /path/to/local/fs

I do get the content of directory on local filesystem as expected with all
correct file attributes (user/group ownership, creation time, content).
However, the source files on moosefs change their time stamps, as if the
report last access time instead of creation time. They were reporting
correct creation times after they were rsync'ed from local filesystem to
moosefs originally. This basically renders rsync command useless (and
damaging if you care about file creation times) when you rsync from
moosefs (elsewhere).

What am I doing wrong? I've used Linux and Unix for over decade an a half,
ans used rsync over comparable period of time. What I hit with moosefs
gives me kind of shock, and I can't figure myself what could I be doing
wrong.

Thanks in advance for all your advices.

Valeri
