Hello DM multipath developers,

I've been messing quite a while today with getting my blacklisting for a system right. The current solution works; blacklisting all internal disks by wwid, but I still think its sub-optimal.

Wouldn't it be easier to make the blacklist and whitelist behave just like IPtables or PostFix ? That is as soon as the first decision is made its done. I think it would also be easier to code as it would be a list of regular expressions which need to be matched and the first one triggering wins.

With that solution the config for most setups would be something like:

whitelist {
       device {
               vendor  "My SAN vendor"
               product "My SAN product"
       }
}

blacklist {
        devnode "*"
}

This would make configuration alot easier than it is right now when I have to blacklist all the 'non multipath' devices.

Kind regards,

Arno

This non-optimal setup still exists, and proposals for a better whitelist/blacklist have been discussed on dm-devel, but no work has been done on it yet.
