SYNTAX
lamclean [-hv]
OPTIONS
- -h
- Print the command help menu.
- -v
- Be verbose.
DESCRIPTION
The lamclean command attempts to remove
all user processes and messages from all nodes. It also
de-allocates all user allocated resources and cancels all user
process registrations. This happens by invoking many different
remote services which have previously been invoked individually by
several other commands. These commands should still be used when
partial selective removal of user presence is desired. Otherwise,
lamclean is a quick and convenient way of starting over
after a bad application run without rebooting the system.
lamclean takes the following actions on the following
system processes on all nodes:
- kenyad
- The LAM SIGUDIE signal (terminate) is sent to all user
processes. See doom(1).
- bufferd
- The entire daemon is reset to its initial state after booting.
See sweep(1).
- filed
- All user file descriptors are closed. See fctl(1).
- traced
- All traces are removed. See lamtrace(1).
lamclean will not succeed if any of the nodes are
unreachable due to catastrophic failure or maximum buffer overflow
with link jamming. If lamclean does not return, use lamwipe(1)
and lamboot(1) to
restart the multicomputer.
