You might be hitting a multipath config issue.

On a 4.3.4. node-ng cluster I had a similar problem.  spare disk was on /dev/sda  (boot disk was /dev/sdb)

I found this link https://stackoverflow.com/questions/45889799/pvcreate-failing-to-create-pv-device-not-found-dev-sdxy-or-ignored-by-filteri

which led me to lsblk /dev/sda and then add the "displayed wwid" to the multipath.conf blacklist.
after restarting multipathd, I was able to use the cockpit wizard to install gluster on /dev/sda.

I am installing ovirt 4.2 on three nodes. I am using centos with ovirt cockpit. My /sdb is my boot disk and /sda is my local storage,

When I started the setup with cockpit I selected the sda but the ansible script stay on sdb. I have fix all changing the playbook manually but in the execution the gdeploy tool stay blocked on TASK [Create Physical Volume] .

I don't find any logs. How I can fix that?
