I was having this error earlier today in my lab environment I didn't resolve it and gave up!

Prior to the messages you mention, I noticed something about "multipath -a /dev/sdb" which was failing and for sure you can try that from the command line and see the failure message. I just assumed the 4.4.2 setup scripts require you to have a multipath device as the underlying storage and no longer supported direct attached single disks. I used the current (4.4.2) ovirt node ISO and was trying to deploy on 3 x VMWare Workstation v15 VMs.

[root@ovn3 ~]# multipath /dev/sdb

Nov 02 19:41:54 | sdb: failed to get udev uid: Invalid argument

Nov 02 19:41:54 | sdb: failed to get sysfs uid: Invalid argument

Nov 02 19:41:54 | sdb: failed to get sgio uid: No such file or directory

[root@ovn3 ~]# echo $?

I instead manually configured the gluster fs first and then deployed the hosted engine, I am unfamiliar but next I need to add my 2nd and 3rd gluster nodes as KVM compute nodes, but that's for tmrw now. I'm not sure if I can use the 3rd gluster node as a KVM compute node as that was marked as arbiter.

Here's my success run, if it's any use to you:

parted /dev/sdb mklabel gpt

parted /dev/sdb mkpart primary 0% 100%

mkfs.xfs -i size=512 -Lglusterfs /dev/sdb1

echo 'LABEL=glusterfs /data/glusterfs/myvolume/mybrick xfs defaults 0 0' >> /etc/fstab

(This to preload the appliance RPM into yum cache rather than download it again:)

[ovn1]#

mkdir -p /var/cache/dnf/ovirt-4.4-8fb26fb2b8638243/packages

cp ovirt-engine-appliance-4.4-20200916125954.1.el8.x86_64.rpm /var/cache/dnf/ovirt-4.4-8fb26fb2b8638243/packages

Hosted Engine

VM -> Engine -> PrepareVM

Standard options

Storage

I added the gluster storage as ovn1.int.ajc:/myvolume

Tadaaaa!

Hey!

In case you are deploying on any server which is not RHVH based, the devices are not automatically blacklisted.
Or it could be because the disk was previously partitioned.
You can try these solutions if they help -

If the filter is correct (/etc/lvm/lvm.conf) and old partition table information found on the disk, you can wipe out the old partition information with "wipefs".

wipefs -a /dev/sdx

In case the filter is incorrect then you can edit the /etc/lvm/lvm.conf and add this parameter under the filter

"a|^/dev/sdx$|"
