copyfs-mount

COPYFS-MOUNT(1) 						   User Commands						   COPYFS-MOUNT(1)

NAME

       copyfs-mount - mounts a versioned file system

SYNOPSIS

       copyfs-mount version-directory mount-point

DESCRIPTION

       This  script lets you mount a CopyFS file system. version-directory is the directory where the files and version information will be stored
       by CopyFS.

       When using CopyFS for the first time, copyfs-mount will create the required files in the version-directory  before  running  copyfs-daemon.
       mount-point is the directory where the copyfs file system will be mounted. This is where the users will have access to the files.

       If you want to mount a CopyFS at '/mnt/fs', whose version directory is at /var/versions, you would use:

	    root@host# copyfs-mount /var/versions /mnt/fs

       To unmount it, simply do:

	    root@host# umount /mnt/fs

       As you would do for any other filesystem.

       You  can also allow an ordinary non-root users to mount and unmount CopyFS filesystems provided that the user is added to the 'fuse' group.
       Ordinary users will be able unmount the filesystem, using the fusermount command:

	    $ fusermount -u mount-point
