Re: [ovirt-users] ovirt 3.5 self-hosted engine and ovirtmgmt not syncronised
Donny Davis писал 2015-01-23 18:07:
You have to move the hosted engine to another host to sync the
networks, they cannot be synced while the host is running vm's. Bring
your second hosted engine machine online so the engine can be
migrated, and the host in which you want to sync the network can be
synced.
I only know from experience, and one of the ovirt devs may have a
better solution. This is what worked for me.
Hmmm...
I was able to sync ovirtmgmt network on two hosts out of three but now I
have a problem starting engine up on those two nodes

How can I recreated that ifcfg-ovirtmgmt file?

[ovirt-users] Host remains Non-Responsive after reboot
I am running oVirt Engine Version 3.5.0.1-1.el6. I have 4 hosts in the cluster. Each host has a drac5 and it is configured and working. I am trying to simulate a node failure. I am running one HA VM on one of the hosts for testing. I simulate the failure by powering off the host with the VM running. Here is what is happening. * Host is powered off * ~4 minutes pass and the host is recognized as not responding * Automatic fence runs and the VM migrates.Another host in the node is chosen as a proxy to execute Status command on the host. * Same host is chosen as proxy to execute Start command on the host. * Same host is chosen as proxy to execute Status command on the host. * The host DOES physically start. * The host never shows status of UP. * I select “confirm host has been rebooted” and I see a manual fence start. * Host stays non-responsive. * I put the host in maintenance and then activate it. * Host still non-responsive * I put the host in maintenance and do a reinstall * Reinstall finishes and host becomes UP So, everything seems to go fine with the HA functionality, but the host never recovers without being reinstalled. Please let me know which logs you need to look at to help me out with this.

[ovirt-users] Update to 3.5.1 scrambled multipath.conf?
Hello,
on my all-in-one installation @home I had 3.5.0 with F20.
Today I updated to 3.5.1.
it seems it modified /etc/multipath.conf preventing me from using my second
disk at all...
My system has internal ssd disk (sda) for OS and one local storage domain
and another disk (sdb) with some partitions (on one of them there is also
another local storage domain).
At reboot I was put in emergency boot because partitions at sdb disk could
not be mounted (they were busy).
it took me some time to understand that the problem was due to sdb gone
managed as multipath device and so busy for partitions to be mounted.
Here you can find how multipath became after update and reboot
https://drive.google.com/file/d/0BwoPbcrMv8mvS0FkMnNyMTdVTms/view?usp=sharing
No device-mapper-multipath update in yum.log
Also it seems that after changing it, it was then reverted at boot again (I
don't know if the responsible was initrd/dracut or vdsmd) so in the mean
time the only thing I could do was to make the file immutable with
chattr +i /etc/multipath.conf
and so I was able to reboot and verify that my partitions on sdb were ok
and I was able to mount them (for safe I also ran an fsck against them)
Update ran around 19:20 and finished at 19:34
here the log in gzip format
https://drive.google.com/file/d/0BwoPbcrMv8mvWjJDTXU1YjRWOFk/view?usp=sharing
Reboot was done around 21:10-21:14
Here my /var/log/messages in gzip format, where you can see latest days.
https://drive.google.com/file/d/0BwoPbcrMv8mvMm1ldXljd3hZWnM/view?usp=sharing
Any suggestion appreciated.
Current multipath.conf (where I also commented out the getuid_callout that
is not used anymore):
[root@tekkaman setup]# cat /etc/multipath.conf
# RHEV REVISION 1.1
blacklist {
devnode ^(sda|sdb)[0-9]*
}
defaults {
polling_interval5
#getuid_callout /usr/lib/udev/scsi_id --whitelisted
--replace-whitespace --device=/dev/%n
no_path_retry fail
user_friendly_names no
flush_on_last_del yes
fast_io_fail_tmo5
dev_loss_tmo30
max_fds 4096

I want to query the RHEV-Manager and would like to get the details of MAC address without activating it. Do you have the script to do this.

Re: [ovirt-users] oVirt 3.5.1 ; No Network Access on hosted engine vm

My VM doe not have network access. The interface is connected and setup within the VM just no network access. Is there a way I can change the bridge interface? Hi Mikola, if you was able to complete hosted engine deploy and so the engine is up and the host is already managed by the engine you could simply access somehow the engine web admin UI (if you was able to complete the deploy at least the host is able to connect to the engine REST APIs) and you cold simply setup host network from there changing the bindings of ovirtmgmt logical network to the other physical interface. If your deploy is still pending and cannot complete due to wrong network configuration I'd suggest to cleanup and restart from scratch cause it would be easier and safer.
