Hi,
I implemented live migration for the VDC driver a few weeks back and on the
whole it seems to work
quite well. The "premigrate" script creates a cache instance on the target
server and puts the source
cache into proxy mode, then the "postmigrate" script kills the original cache
instance.
Problem :: if the migration fails, I'm left with a running cache on both the
source and target servers, with
the source cache in proxy mode. I have a 1-line CLI command to revert the
issue, but I need to hook into
the system in order to call it.
How to do I do this, I guess effectively I need something like
"postmigrate_fail" .. ???
