The vcsmmdebug command sets the appropriate debug flag in the kernel for the VCSMM driver and can be used to print the debug log.
-s or -u opt Set up debugging of VCSMM driver setting or clearing the appropriate flag. -s will set the option, and -u will unset it. The arguments for opt, are as follows:
all - always print all debug messages
lists - list manipulations
interface - interface to vcsmm driver
request - broadcast requests from vcsmm
reconfig - cluster reconfiguration
group - application / process groups
snap - snapshot sent / received
pref - "PREF"
buffer - buffer related stuff
syslog - copy syslog messages
other - miscellaneous types not categorized above
dbgmsg - debug point
errmsg - error point
-p Print various pieces of information about the driver state or its history. The type argument may be one of:
memb - current node membership
state - the cluster state
stats - io statistics
dbglog - debug log
msglog - message log
dbgcat - current debug mask
dbgmsg=x - value of debug point x
errmsg=x - value of error point x
-D Print the kernel data structures for VCSMM. -A Print the kernel data structures for VCSMM on all nodes to the syslog. These data are syncronized with a GAB broadcast and should all be the same. -t Print information about the tunable parameters. -h Display usage for command.
To set flag to dump broadcast request and snapshot messages, set:To set flag to dump messages of the interface to the vcsmm driver, of groups, and snapshots, set:vcsmmdebug -s request,snap
