From 640c2b57f0f3e7256d587ddd5960341cb38b1982 Mon Sep 17 00:00:00 2001

Subject: [PATCH] LVM-activate: Fix return codes
OCF_ERR_ARGS should be used when the configuration isn't valid for the
**local** node, and so the resource should not attempt to start again
locally until the issue is corrected.
OCF_ERR_CONFIGURED should be used when the configuration isn't valid on
**any** node, and so the resource should not attempt to start again
anywhere until the issue is corrected.
One remaining gray area: Should lvmlockd/lvmetad/clvmd improperly
running (or improperly not running) be an OCF_ERR_GENERIC or
OCF_ERR_ARGS? The fact that it's a state issue rather than a config
issue suggests OCF_ERR_GENERIC. The fact that it won't be fixed without
user intervention suggests OCF_ERR_ARGS. The approach here is to use
GENERIC for all of these. One can make the case that "improperly
running" should use ARGS, since a process must be manually stopped to
fix the issue, and that "improperly not running" should use GENERIC,
since there's a small chance the process died and will be recovered in
some way.
More info about return code meanings:

Subject: [PATCH 1/2] Make storage_mon -h exit just after printing help
messages.
Previously, when -h or an invalid option was specified, storage_mon
printed the help messages, proceeded processing and then could
throw an error. This was not the behavior that, e.g., users who want
to specify -h option to see the help messages are expecting. To fix
this issue, this commit changes storage_mon so that it exits just
after printing the help messages when -h or an invalid option is
specified.

Subject: [PATCH] storage_mon: Fix bug in checking of number of specified
scores.
Previously specifying the maximum allowed number (MAX_DEVICES, currently 25)
of devices and scores as arguments could cause storage_mon to fail unexpectedly
with the error message "too many scores, max is 25". This issue happened
because storage_mon checked whether the number of specified scores
exceeded the upper limit by using the local variable "device_count" indicating
the number of specified devices (not scores). So after the maximum number
of devices arguments were interpreted, the appearance of next score argument
caused the error even when the number of interpreted scores arguments had
not exceeded the maximum.
This patch fixes storage_mon so that it uses the local variable "score_count"
indicating the number of specified scores, to check whether arguments for
scores are specified more than the upper limit.

Subject: [PATCH] Fix bug in handling of child process exit.
When storage_mon detects that a child process exits with zero,
it resets the test_forks[] entry for the child process to 0, to avoid
waitpid() for the process again in the loop. But, previously,
storage_mon didn't do that when it detected that a child process
exited with non-zero. Which caused waitpid() to be called again
for the process already gone and to report an error like
"waitpid on XXX failed: No child processes" unexpectedly.
In this case, basically storage_mon should wait until all the child
processes exit and return the final score, instead.
This patch fixes this issue by making storage_mon reset test_works[]
entry even when a child process exits with non-zero.
