Re: [ovirt-users] Slow booting host - restart loop

[Bernardo Juanicó]

Hi Eli,

I could not access the psql prompt, i tried with the credentials and values
on /etc/ovirt-engine/engine.conf.d/10-setup-database.conf.

I tried interactively and also with a .pgpass file containing:
localhost:5432:engine:engine:PASSWORD

And i get the following error:

psql: FATAL:  Peer authentication failed for user "engine"

Thanks!

 Hi everyone,

 I installed 2 hosts on a new cluster and the servers take a really long
 to boot up (about 8 minutes).

 When a host crashes or is powered off the ovirt-manager starts it via
 power management, since the servers takes all that time to boot up the
 ovirt-manager thinks it failed to start and proceeds to reboot it, several
 times before giving up, when the server is finally started (about 20
 minutes after the failure)

 I changed some engine variables with engine-config trying to set a
 higher timeout, but the problem persists.

 Any ideas??

 Bernardo

Re: [ovirt-users] Slow booting host - restart loop

[Eli Mesika]

Hi Bernardo

I would like to suggest a workaround to this problem , can you please check
that :

We have a configuration value named FenceQuietTimeBetweenOperationsInSec.
It controls the minimal timeout to wait between fence operation (stop,
start),
currently, it is defaulted to 180 sec , The key is not exposed to
engine-config, so, I would suggest to

1) Change this key value to 900 by running the following from psql prompt :

update vdc_options set option_value = '900' where option_name =
'FenceQuietTimeBetweenOperationsInSec';

2) Restart the engine

3) Repeat the scenario

Now, the engine will require 15 min between fencing operations and your
host can be up again without being fenced again.

Please let me know if this workaround is working for you

Thanks

Eli

Generally speaking this is not supported. See also:

https://www.ovirt.org/develop/release-management/features/storage/mixed-types-data-center/
https://www.ovirt.org/develop/release-management/features/storage/decommission-master-domain-and-spm/

The closest thing you can use is the localdisk vdsm hook:

Is your only reason being that you want to use the (presumably large,
fast, cheap) local disk instead of the (small or slow or expensive)
shared storage?

You can use also other means to achieve the same. Many people these days
use gluster, some use, or at least tried, other technologies - e.g. ceph, drbd,
gfs2, ocfs2 - search the list archives. Most, if not all, of these, are meant
to provide HA storage using local disks, and therefore waste more total storage,
compared to "just" use the local disk for local VMs.

You can also use the following hack:

1. On each of your hosts, create two VMs using other means (e.g. virsh),
and configure them to allow nested-kvm. One small, which will be used for the
hosted-engine hosts, and one large, for the other hosts' VMs
2. Deploy hosted-engine on the small VMs with your shared storage.
3. Add the large VMs as hosts with local storage
4. Then create your VMs on whatever DC/cluster you want - HA ones on the
small VMs (or just keep them only for the hosted-engine vm), others on
one of the local-disk hosts.

Best,

If the engine VM is up, but the GUI is down, I think that either Apache or 
Jboss is down. Apache is unlikely, so I would guess Jboss. To figure out why 
Jboss is down look in /var/log/ovirt-engine/ at boot.log, and server.log, also 
check out engine.log but the first two should tell you why Jboss is down.

Especially if you don't use snapshots, I think the default of raw-sparse is
the way to go for you. It allocates the full disk space, but does not
occupy it. So it's not thin provisioned, but sparsely provisioned.

I remember Gluster supporting DISCARD.

Re: [ovirt-users] Slow booting host - restart loop

[Martin Perina]

Hi Bernardo,

we have added timeout to wait until host is booted [1] in oVirt 4.1.2. This
timeout is by default 5 minutes, but it can be extended using following
command:

   engine-config -s ServerRebootTimeout=NNN

where NNN is number of seconds you want to wait until host is booted up.

But be aware that you may be affected by [2], which we are currently trying
to fix.

Regards

Martin Perina

[ovirt-users] Someone can give me advice about Ovirt?

[Khoi Thinh]

Hi everyone,
Here's my use case of using Ovirt

I want to store only virtual machine of "Hosted engine" to Shared Disk, in
addition i also want to store other virtual machine to "Local disk"
For "Hosted engine", i want to built it with High Availability.
There's no need for High Availability for other virtual machine.
Because i want to use HDD's capacity of Host server, so i'm considering the
above-mention structure/design.

What do you think about this? Any advice/thoughts would be appreciate.

We never checked WiFi interfaces or planned to work with wireless
NICs. If you are interested in using wireless NICs on oVirt hosts,
you are welcome to open a bug which explains how you like to use
wireless networking and the reason for using it.
