The easiest way to get vdsm defaults is to change the the file to use
an older version,
(e.g. use 1.9), remove the private comment, and run:
vdms-tool configure --force --module multipath
Vdsm will upgrade your old file to the most recent version, and backup
your old file
to /etc/multipath.conf.timestamp.
thanks
For 120 seconds, you likey need
sanlock:io_timeout=20
no_path_retry=32
Shouldn't the above values for a 160 seconds timeout? I need 120
Because of the different way sanlock and multipath handles timeouts.
Also note that our QE never tested changing these settings, but your
feedback on this new
configuration is very important.
ok
multipath -r deleages the command to multipathd daemon, this is
probably the reason
you don't see the logs here.
I think this will be more useful:
multipathd reconfigure -v3
I'm not sure about the -v3, check multipathd manual for the details.

On another host with same config (other luns on the same storage), if I run:
multipath reconfigure -v4 > /tmp/multipath_reconfigure_v4.txt 2>&1
I get this:

anything important inside, concerned with path retry settings?
