Usage: ceph-dokan.exe -l <mountpoint>
map -l <mountpoint> Map a CephFS filesystem
unmap -l <mountpoint> Unmap a CephFS filesystem
Map options:
-l [ --mountpoint ] arg mountpoint (path or drive letter) (e.g -l x)
-x [ --root-path ] arg mount a Ceph filesystem subdirectory
-t [ --thread-count] arg thread count
--operation-timeout arg Dokan operation timeout. Default: 120s.
--debug enable debug output
--dokan-stderr enable stderr Dokan logging
--read-only read-only mount
-o [ --win-mount-mgr] use the Windows mount manager
--current-session-only expose the mount only to the current user session
--removable use a removable drive
--win-vol-name arg The Windows volume name. Default: Ceph - <fs_name>.
Unmap options:
-l [ --mountpoint ] arg mountpoint (path or drive letter) (e.g -l x).
It has to be the exact same mountpoint that was
used when the mapping was created.
