Re: Multipath blacklisted devices

[Arsene Gschwind <arsene.gschwind@unibas.ch>]

Hi Christophe,

I've found the problem, my entry in multipath.conf was devnode_blacklist 
{ } and it should be only blacklist{}.
You may have to correct multipath.conf.synthetic provided by the tarball 
( and the git version) because I've used that file to create my own and 
it includes this error.

Thanks a lot for your help and work
Arsène
