Re: [ovirt-users] Self hosted engine iusses

Thursday, 5 February 2015

I ran into this same problem after setting up my cluster on EL7. As has 
been pointed out, the hosted-engine installer modifies /etc/multipath.conf.

I appended:

blacklist {
         devnode "*"
}

to the end of the modified multipath.conf, which is what was there 
before the engine installer, and the errors stopped.

I think I was getting 253:3 trying to map which don't exist on my 
systems. I have a similar setup, md raid1 and LVM+XFS for gluster.
