[dm-devel] Temporarily squelching multipathd errors



Greetings,
 
I perform SAN-based snapshots on OCFS2 and ext3 filesystems under
dm-multipath.  Before I snapshot the filesystem, I unmount and delete
the previous night's snapshot LUNs.  Doing so causes (correctly)
multipathd to output the following errors:
 
<snip>
...
Jul 14 03:16:02 ausracdbd01 multipathd: mpath19: remaining active paths:
7
Jul 14 03:16:02 ausracdbd01 multipathd: sdci: tur checker reports path
is down
Jul 14 03:16:02 ausracdbd01 kernel: device-mapper: multipath: Failing
path 69:80.
Jul 14 03:16:02 ausracdbd01 multipathd: sdco: tur checker reports path
is down
....
</snip>
 
During this snapshot time, I would like to temporarily turn off the
verbosity of multipathd.  Is this possible?  It's mostly an annoyance
factor for me because our nightly centralized syslog scan picks up words
like 'fail' and generates a report to the system administrators (which
we then have to ignore for these messages).
 
TIA,

Daniel
