If the disk was previously used, you may need to 'wipefs -a /dev/sdb' to clean out any previous partitioning, etc. If the installer can't create the gluster PV, it is often because the drive needs to be added to the multipath blacklist. lsblk to find the ID and add it to the /etc/multipath.conf blacklist [root@ovirtnode2 ~]#lsblk /dev/sdb NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sdb 8:16 0 200G 0 disk -> 3678da6e715b018f01f1abdb887594aae 253:2 0 200G 0 mpath edit /etc/multipath.conf and append the disk wwid to multipath.conf blacklist blacklist { wwid 3678da6e715b018f01f1abdb887594aae } then restart the multipathd service service multipathd restart On Tue, Feb 9, 2021 at 2:19 PM Strahil Nikolov via Users <users@ovirt.org> wrote:
What is the output of 'lsblk -t' ?

Ovirt newbie here - using v 4.4.4
Have been trying for days to get this installed on my HP DL380p G6. I have 2 disk 170GB Raid 0 for OS and 6 x 330GB disk Raid 5 for Gluster. DNS all set up (that took some working out), but I just can't fathom out whats (not) happening here. Block size is returned as 512.
I've had some help on Reddit where I've been told that Ovirt is seeing my single local disk ass an multipath device, which it is not/??! I think I removed the flag, but it still fails here.
So, Gluster install fails quite early through, though it carries on creating all the volumes (with default settings) but then gives me the 'Deployment Failed' message :( Here is where it fails....
Any help gratefully received!
