I am currently running a 2 node GFS cluster. The storage is provided via
a fiber channel connection to the SAN. Each node currently has a single
FC connection to the SAN. I would like to migrate to using dm-multipath
with each node having dual fiber channel connections to the SAN. Can I
assume that CLVM is aware of the /dev/dm-# devices that are used to
access the multipathed devices? Are there any gotchas that are
associated with installing the device-mapper-multipath software after
the GFS cluster is up and running? Are there any howtos available for
this type of setup?
Regards and TIA,
