Thank you very much Semi. The reinstallation would not be an problem, being the fact that i've spent so much in sorting this issue. I don't understant the "setup a blacklist part" . What does this mean, how should I do it ? I have looked over the other oVirt nodes that I have in the network, and the mpath is active on their rootfs as well. I have used the 4.2-2018052606.iso image for instalation for cluster nodes and for single instance too. Would it be possible to have a bug in this version ? What iso should I use just to be sure everything will work good ? Again, thank you very much ! On Tue, Jun 12, 2018, 21:54 femi adegoke <ovirt@fateknollogee.com> wrote:

It looks like the same error I had where oVirt keeps "trying" to use the multipath disk as part of the install.

The solution (unfortunately) is to re-install the o/s, then setup a blacklist & then proceed with the rest of the ovirt install.

There is no way to release that disk from multipath since it is part of the root filesystem. _______________________________________________ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-leave@ovirt.org Privacy Statement: https://www.ovirt.org/site/privacy-policy/ oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/JIE7GPJSBVSOMG...

You need to create a file, you can name it local.conf, create it in this location: /etc/multipath/conf.d/

Use the most current iso.

I think there might be a bug. _______________________________________________ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-leave@ovirt.org Privacy Statement: https://www.ovirt.org/site/privacy-policy/ oVirt Code of Conduct: https://www.ovirt.org/community/about/community- guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/ message/SWNMBQSIM74657FALFANBLAMR2VKXLHI/

That was just me being stupid.... I was passing wrong values to the key for volumes. I am running again the playbook. On Wed, Jun 13, 2018 at 10:22 AM, femi adegoke <ovirt@fateknollogee.com> wrote:

Thank you, The playbook just finnished successfully. Now: 1. Should I create the blacklist acordingly: kblacklist { wwid INTEL_SSDSCKHB120G4_BTWM65160025120B wwid eui.0025385171b04d62 wwid SAMSUNG_MZ7GE960HMHP-000AZ_S1P8NYAG123827 } - but not sure what to put as wwid 2. How to deploy self-hosted engine vm, since when I hit any of the "Hosted engine" or "Hyperconverged" it does not recognize the already gluster setup ? 3. Will I be able to create some future gluster volumes using the other unused hdds ? From Cockpit, or again using gdeploy ? I am really sorry if i put stupid questions, but i just don't understand how to proceed further On Wed, Jun 13, 2018 at 10:23 AM, femi adegoke <ovirt@fateknollogee.com> wrote:

Gluster volumes are started, so I assume that the gluster part is fine. Would'nt make more sense to add everything to black list, reboot the server and continue with ovirt-engine vm setup ( and adding 10.10.8.111:/engine for vm storage ) ? ie: blacklist { devnode "*" } Thank you !

It's blacklist { not kblacklist (remove the "k")

run this command to find wwids: ls -la /dev/disk/by-id/

Is the existing gluster setup installed correctly? _______________________________________________ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-leave@ovirt.org Privacy Statement: https://www.ovirt.org/site/privacy-policy/ oVirt Code of Conduct: https://www.ovirt.org/community/about/community- guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/ message/W47PLDI3RYTGXVVFXORYPMJ2YH77XAY2/

Since this is a single node gluster install, you have to add the gluster volume. Log into the HE web gui go to Storage, Storage Domains, click on "New Domain" (it's located at the top right side) Storage Type: select GlusterFS Export Path: enter in this format "myserver.mydomain.com:/my/local/path" Click ok Wait for it to do it's thing

No problem Leo. Glad it worked out ok!!
