automounter query tool
provides a simple way of determining the
current state of the amd(8)
program. Communication is by RPC. Three modes of operation are supported by
the current protocol. By default a list of mount points and auto-mounted
filesystems is output. An alternative host can be specified using the
If directory names are given, as output by default, then per-filesystem
information is displayed.
The options are as follows:
- Request automounter to flush the internal caches.
- Query alternate host
hostname. By default the local host is
used. In an HP-UX cluster, the root server is queried by default, since
that is the system on which the automounter is normally run.
- Request the automounter to provide a list of mounted
filesystems, including the number of references to each filesystem and any
error which occurred while mounting.
- Request the automounter to provide system-wide mount
- Request the automounter to unmount the named filesystems
instead of providing information about them. Unmounts are requested, not
forced. They merely cause the mounted filesystem to timeout, which will be
picked up by amd(8)´s
main scheduler thus causing the normal timeout action to be taken.
- Request the automounter to provide version information.
