lio_fuse [FUSE_OPTIONS] mount_point –lio [LIO_COMMON_OPTIONS]


L-Store Linux FUSE driver for mounting L-Store on a Linux system. The FUSE and L-Store options must be segregated in order to use the FUSE argument parser. This is accomplished by adding the –lio flag which acts as the deliminator.

For a full ist of available FUSE mounting options see the FUSE man page or web site.
