NAME
lamclean - Attempt to clean entire LAM system.
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.
