No need, we can simply keep the names. As long as they live in their own provider directory, they won't cause any conflicts. Pacemaker will happily distinguish between ocf:heartbeat:iSCSI* and ocf:iet:iSCSI*. That's what the provider scheme is designed for. > Since you're thinking of reworking them maybe you could use some > of the newer capabilities.

That would be real tricky to express in Pacemaker's logic, so I'll stick with an IP address failover based scheme for the time being. > Also you can delete live connections and sessions, This will come in very handy. > there's NOP-In keepalives, etc. > > If you have any questions feel free to ask. Will do. Be a bit patient with me though; my availability will be extremely limited for the next 2 1/2 weeks, so it may be till end of June, early July before I have a patch ready. Cheers, Florian
