Hello, I've noticed that the LVM RA is very chatty, it fills the log of
the node where it runs with this lines:
lrmd: [3329]: info: RA output: (VG:monitor:stderr) File descriptor 4
left open
lrmd: [3329]: info: RA output: (VG:monitor:stderr) File descriptor 5
left open
lrmd: [3329]: info: RA output: (VG:monitor:stderr) File descriptor 6
left open
lrmd: [3329]: info: RA output: (VG:monitor:stderr) File descriptor 7
left open
lrmd: [3329]: info: RA output: (VG:monitor:stderr) File descriptor 8
left open
lrmd: [3329]: info: RA output: (VG:monitor:stderr) File descriptor 9
left open
[...]
LVM[4608]: INFO: File descriptor 4 left open File descriptor 5 left open
File descriptor 6 left open File descriptor 7 left open File descriptor
8 left open File descriptor 9 left open ...

his information is not useful because this is the normal behaviour of a
vgck command.
There is a method to make vgck be more quiet:
http://linux.derkeiler.com/Newsgroups/comp.os.linux.misc/2008-04/msg00435.html
There are also other excessive log lines that I notice when I run a LVM
resource:
lrmd: [3329]: info: RA output: (VG:monitor:stderr) Using volume
group(s) on command line
lrmd: [3329]: info: RA output: (VG:monitor:stderr)
lrmd: [3329]: info: RA output: (VG:monitor:stderr) Finding volume
group "VGM"
Now this is determined by the command
vgdisplay -v $1 | grep -i 'Status[ \t]*available' >/dev/null
that not redirect all the output on /dev/null.
The command should be:
vgdisplay -v $1 2>/dev/null | grep -i 'Status[ \t]*available' >/dev/null
I propose this patch to solve the problems above
