Aanother option - you do not have blacklist section in multipath (requires rebuild of initramfs + reboot).

Good Morning,

I'm completely new to this and I'm testing setting up a Gluster environment with Ovirt. However, my deployment keeps fails and I don't understand what it means. Any assistance would be much appreciated. Please see error below...

Error Message

TASK [gluster.infra/roles/backend_setup : Create volume groups] ****************
failed: [ov1.test1.lan] (item={u'vgname': u'gluster_vg_sdb', u'pvname': u'/dev/sdb'}) => {"changed": false, "err": "  /dev/sdb: open failed: No medium found\n  Device /dev/sdb excluded by a filter.\n", "item": {"pvname": "/dev/sdb", "vgname": "gluster_vg_sdb"}, "msg": "Creating physical volume '/dev/sdb' failed", "rc": 5}

One of the reasons for this is, the device could be having an existing partition table information.

Can you please run the command:

wipefs -a /dev/sdb

On all the nodes and try again?
