I ask because we've had a couple of reports of hanging/freezing servers when actually they had crashed. The way to figure it out is to let us have the complete log file, or at least the last few hundred lines. > I would also like to mount a path like: /volume/some/random/dir > > # mount host:/gluster/tmp /mnt/test > mount: host:/gluster/tmp failed, reason given by server: No such file or > directory > > I can mount it up host:/volume_name and /mnt/test/tmp exists > I see you're trying to mount a directory from a GlusterFS subvolume as an NFS export by itself. This is not supported in the Alpha release. NFS server right now allows each GlusterFS subvolume to be a single NFS export. We are, however, planning to introduce this functionality in the near future.
