Gluster suggestions
by Magnus Isaksson
Hello
I would like some suggestions on what type of solution with Gluster i should use.
I have 4 hosts with 3 disks each, i want to user as much space as possible but also some redundancy, like raid5 or 6
The 4 hosts are running oVirt on CentOS 7
I have 2 clusters due to some licensing issues, so i cant use ovirts setup of gluster
Today i have set it up as follows
Type: Disperse
Number of Bricks: 1 x (8 + 4) = 12
So i have 3 bricks per host (one brick per disk)
But this setup is not working very well, as soon as i get some traffic on the volume this start to fail on the ovirt nodes, loosing connection etc.
All hosts are connected via 10G interface
So any suggestions on how i would set this up as best is much appreciated.
Regards
Magnus Isaksson

active directory: how to replace user@corp.mydomain.com with user@mydomain.com
by Jarosław Prokopowski
I configured active directory authentication but the problem is I need to replace user(a)corp.mydomain.com with user(a)mydomain.com to be able to authenticate.
ovirt-engine-extension-aaa-misc has been installed and I configured it as shown below but still it is not working. Do you have any idea what is wrong and how to fix it?
/etc/ovirt-engine/aaa/corp.mydomain.com.properties:
--------------------------------------------------
include = <ad.properties>
vars.domain = corp.mydomain.com
vars.user = CN=user,DC=xxx,DC=corp,DC=mydomain,DC=com
vars.password = password
pool.default.auth.simple.bindDN = ${global:vars.user}
pool.default.auth.simple.password = ${global:vars.password}
pool.default.serverset.type = srvrecord
pool.default.serverset.srvrecord.domain = ${global:vars.domain}
/etc/ovirt-engine/extensions.d/mapping.properties:
-------------------------------------------------
ovirt.engine.extension.name = mapping
ovirt.engine.extension.bindings.method = jbossmodule
ovirt.engine.extension.binding.jbossmodule.module = org.ovirt.engine-extensions.aaa.misc
ovirt.engine.extension.binding.jbossmodule.class = org.ovirt.engineextensions.aaa.misc.mapping.MappingExtension
ovirt.engine.extension.provides = org.ovirt.engine.api.extensions.aaa.Mapping
config.mapUser.type = regex
config.mapUser.regex.pattern = ^(?<user>[^@]*)$
config.mapUser.regex.replacement = ${user}(a)mydomain.com
config.mapUser.regex.mustMatch = false
ovirt.engine.aaa.authn.mapping.plugin = mapping
In the engine logs I see mapping loaded:
-------------------

Gluster arbiter volume storage domain - change
by Leo David
Hi Everyone,
I have wrongly configured the main gluster volume ( 12 identical 1tb ssd
disks, replica 3 distributed-replicated, across 6 nodes - 2 per node ) with
arbiter one.
Oviously I am wasting storage space in this scenario with the arbiter
bricks, and I would like to convert the volume to non-arbitrated one, so
having all the data evenly spreaded across all the disks.
Considering the the storage is being used by about 40 vms in production,
what would it be the steps, or is there any chance to change the volume
type to non-arbitrated on the fly and then rebalance ?
Thank you very much !

Even if you run gluster outside of oVirt, you are using the disperse
volume as storage domain?
For a supported config, you can create a distributed-replica+arbiter
gluster volume. Since you have 12 disks, you can use a 5 x 3 (arbiter)
setup, where a disk is partitioned to multiple arbiter bricks,
something like this (c11,c12, a31, a32 are arbiter bricks) :
a1 b1 c11
a2 b2 c12
b3 c13 d1
a31 c2 d2
a32 c3 d3

sysprep properties file
by Florian Rädler
How can i overwrite the credentials in the sysprep.w10x64 file.
I have created a file /etc/ovirt-engine/osinfo.conf.d/10-domainjoin.properties
Which contains the following:
os.windows_10x64.identification.credentials.domain.value = logondomain
os.windows_10x64.identification.credentials.password.value = xxxxxxxx
os.windows_10x64.identification.credentials.username.value = username
os.windows_10x64.joindomain.value = joindomain
If I change the credentials section in /usr/share/ovirt-engine/conf/sysprep/sysprep.w10x64
the domainjoin works.
What did I wrong?
Thanks for your help.
BR
Florian

Can you check if there are any errors in the engine volume's mount
logs (/var/logs/glusterfs/rrhev-data-center-mnt-glusterSD-<engine
volume>.log)

Gluster suggestions
by magnus＠vmar.se
Hello
I would like some suggestions on what type of solution with Gluster i should use.
I have 4 hosts with 3 disks each, i want to user as much space as possible but also some redundancy, like raid5 or 6
The 4 hosts are running oVirt on CentOS 7
I have 2 clusters due to some licensing issues, so i cant use ovirts setup of gluster
Today i have set it up as follows
Type: Disperse
Number of Bricks: 1 x (8 + 4) = 12
So i have 3 bricks per host (one brick per disk)
But this setup is not working very well, as soon as i get some traffic on the volume this start to fail on the ovirt nodes, loosing connection etc.
All hosts are connected via 10G interface
So any suggestions on how i would set this up as best is much appreciated.
Regards
Magnus Isaksson

I tried to stop and start the vm again, but it didnt helped
Maybe someone can give me some advice how to get the hosted engine running
again

Re: Gluster arbiter volume storage domain - change
by Strahil
Just a thought,
Have you considered network bandwidth increase, as your traffic will increase by 50%.
About getting rid of the arbiter, you may check the following:
