Hi all,
I have a system where various configurations are possible - iSCSI/FC,
single paths and multiple. For multiple I of course use device-mapper.
I was wondering if it was possible to:
1. use it for cases where I have a single path.
2. create a monitoring process that can take some action (e.g., send a
notification via message queue) in the case of some failure that would
normally cause failover.
Does dm-multipath support a single path? I don't know...
but for your #2, dm-multipath publishes a uevent when a path fails,
maybe the process could look for that? Using libudev?
