[ovirt-users] Problems installing Ovirt 4.02 Node

Thu Aug 4 09:37:19 UTC 2016

Hi,
I installed ovirt-node-ng-installer-ovirt-4.0-2016080104.iso
with default partitioning Layout
with the result after Installation:

Status: FAILED
Mount points ... FAILED - This can happen if the installation was performed incorrectly
  Separate /var ... FAILED - /var got unmounted, or was not setup to use a separate volume
  Discard is used ... FAILED - 'discard' mount option was not added or got removed
Basic storage ... OK
  Initialized VG ... OK
  Initialized Thin Pool ... OK
  Initialized LVs ... OK
Thin storage ... OK
  Checking available space in thinpool ... OK
  Checking thinpool auto-extend ... OK

No LV for /var created at all.

What’s the right way installing an working node?

Thx a lot
Christian

Now  imgbase status: OK

But I see this in /var/log/messages after the change :  Starting kdump: [FAILED]

I checked messages in my other hypervisor where /etc/fstab was not modified, KDUMP was OK there.

The question about registrating the host in the manager i got solved, it is now done from the manager.
(I come from the Redhat 3.5, and are just started on Ovirt 4)

Nice that the status issue could be solved.
For adding Node, you can either add the host by gpoing to Engine and then add the host, or you can use vdsm register on the host to register it to Engine.

Thanks for helping

Got the same problem, add discard option to fstab for / and /var like this:

#
# /etc/fstab
# Created by anaconda on Fri Jul 22 11:08:40 2016 # # Accessible filesystems, by reference, are maintained under '/dev/disk'
# See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info #
/dev/HostVG/ovirt-node-ng-4.0.2-0.20160721.0+1 / ext4 defaults,discard 1 1
UUID=a96d5a4c-bc4b-481c-bf6e-af47318d8b7b /boot                   ext4
  defaults        1 2
/dev/mapper/HostVG-var  /var                    ext4    defaults,discard 1 2
/dev/mapper/HostVG-swap swap                    swap    defaults        0 0

then remount or reboot.

For this one I can't help, but you can add the new host from the manager..
