LSVFS(1)               DragonFly General Commands Manual              LSVFS(1)


NAME

     lsvfs -- list installed virtual file systems


SYNOPSIS

     lsvfs [vfsname ...]


DESCRIPTION

     The lsvfs command lists information about the currently loaded virtual
     file system modules.  When vfsname arguments are given, lsvfs lists
     information about the specified VFS modules.  Otherwise, lsvfs lists all
     currently loaded modules.  The information is as follows:

     Filesystem  the name of the file system, as would be used in the type
                 parameter to mount(2) and the -t option to mount(8)
     Num         the filesystem type number.
     Refs        the number of references to this VFS; i.e., the number of
                 currently mounted file systems of this type
     Flags       flag bits.


SEE ALSO

     mount(2), getvfsbyname(3), getvfsent(3), mount(8)


HISTORY

     A lsvfs command appeared in FreeBSD 2.0.


BUGS

     In DragonFly's encrypted root setup, lsvfs will show at least 2
     references to ``ufs'' even though just /boot seems to be mounted.  The
     second reference is the initial root from the /boot/kernel/initrd.img.gz
     image.
