NAME¶
lamclean - Attempt to clean entire LAM system.
SYNOPSIS¶
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.
