Re: [ovirt-users] Self hosted engine iusses
I wiped my test cluster and started over. This time I did not do the
devnode blacklist and instead did find_multipaths yes (as is also in
the default EL7 multipath.conf) and that worked fine as well, device
mapper system messages went away.

Here
In vdsm log I see that you installed hosted engine on NFS storage domain; not
having
multipath devices and ovirt vgs/lvs is expected.
Your multipath errors may be related to ovirt, but only because vdsm requires
and starts multipathd, and install new multipath.conf.
I suggest to try to get help about it in device-mapper channels (e.g. #lvm on
freenode).
If you cannot resolve this, please open a bug.

Re: [ovirt-users] Self hosted engine iusses
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

After ovirt installation on host console I see this error every 5 minutes:

This may be caused by the fact that vdsm does not cleanup properly after
deactivating storage domains. We have an open bugs on this.
You may have an active lv using non-existent multipath device.
Can you share with us the output of:
lsblk
multipath -ll
dmsetup table
cat /etc/multipath.conf
pvscan --cache /dev/null lvs

Are you sure this is the correct host that the multipath error came from?
There are no multipath devices in this host and no ovirt storage domains lvs.
Nir
Yes this is the host. I'm sure.
I've not yet configured ovirt storage domains (only installed ovirt on host and
self hosted engine VM)
Here a part of /var/log/messages:

Re: [ovirt-users] Self hosted engine iusses
You can also add “find_multipaths 1” to /etc/multipath.conf, this keeps
multipathd from finding non-multipath devices as multi path devices and avoids
the error message and keeps mutlipathd from binding your normal devices. I find
it simpler than blacklisting and it should work if you also have real multi
path devices.
defaults {
find_multipaths yes

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.
