I know it's not supported, but I tried it out to see what kind of error behaviour I would get.
The following were preformed on a simple ceph filesystem (one monitor, one mds, one osd all on the same machine) running current unstable with the filesystem mounted via cfuse: /mnt# mkdir foo /mnt# cd foo /mnt/foo# cat > something These are the contents of the file. /mnt/foo# cd .snap /mnt/foo/.snap# mkdir old /mnt/foo/.snap# cd .. /mnt/foo# cat > something These are different contents of the file. /mnt/foo# cd .snap /mnt/foo/.snap# ls old/ /mnt/foo/.snap# cd old r...@seasalt:/mnt/foo/.snap/old# ls something /mnt/foo/.snap/old# cat something These are the contents of the file. /mnt/foo/.snap/old# cat > something zsh: invalid argument: something /mnt/foo/.snap/old# cat > somthingelse These are divergent contents. This last command hangs, and in the MDS log I find: mds/CDir.cc: In function 'CDentry* CDir::add_null_dentry(const std::string&, snapid_t, snapid_t)': mds/CDir.cc:225: FAILED assert(lookup_exact_snap(dname, last) == 0) Thank you very much. -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
