[ovirt-users] Problems installing Ovirt 4.02 Node

[Peter Michael Calum]

Hi,

I tried the changes in /etc/fstab and rebooted.
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)

Thanks for helping
Peter

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..
