gluster uses 2+1 arbitration mode
My host is damaged and I need to reinstall the system. The host fqdn still uses
the old fqdn. What should I do?
I found some historical information. Is it still usable for the new version?
Found gluster-ansible in GitHub
import ovirtsdk4 as sdk
import paramiko
import subprocess
# create connection
connection = sdk.Connection(

By default, find the management in engine-web and use ssh management to
restart and stop the node node. Can I get the host's secret key or other
login information to log in through Python, and then send some commands or
scripts?

ovirt version 4.5.1
I didn't see the tutorial on the ovirt official website, but I found the
tutorial of Red Hat Hyperconverged Infrastructure for Virtualization. Should I
follow this tutorial to execute, or through Cockpit, first pass the three
machines of the second cluster through glusterfs
I have many data centers, the first data center contains the engine, the
glusterfs management dashboard can be seen in the Cockpit background, but the
glusterfs management dashboard cannot be seen in the second data center,
Create the second data center step: I create a data center in the
Thank you very much, I am testing in the test environment now, and I will go to
the official environment after success

Thank you very much, I know the operation steps, but there is still one point
that I don’t quite understand, fdisk -l only shows 50G, the actual disk
allocation has 100G, how can I display the remaining 50G.
The second question is that if the allocated 100G is also full, how should I
expand it?
Now my hosting engine /var directory is full, and the 15G free space is fully
occupied. When creating the hosting engine, I use 100G, but actually only use
50G. What can I do to make /var bigger?

I already know why peering fails.
GlusterFS needs to use fqdn, through DNS or hosts file to achieve
When I deployed the first few machines, I used the IP without reporting an
error, and I continued to deploy other machines and reported an error.

I want to add a disk to HostedEngine, and the following error occurs when
adding a disk in the web ui
HostedEngine:
Unable to add virtual disk. The engine is not managing this virtual machine.
Does HostedEngine need to use vdms to add disks?
Is it the following operation

I have many users and each user manages different devices,
I made a label for the corresponding device and distributed the label to the
corresponding user. The user needs to manually activate the label every time he
logs in. How to activate the label by default?
I have configured ldap and can use ldap users to log in to the web engine

I modified the parameter of SSO_ALTERNATE_ENGINE_FQDNS to the new fqdn in
/etc/ovirt-engine/engine.conf.d/11-setup-sso.conf.
After modifying the hosts, I can use the new fqdn to open the web but cannot
enter the portal management, prompting 500 Internal Server Error
Is the DB vacuum cleaning thorough?
I tried that a long time ago and it didn't seem to clear much space.
Is the data recorded in DB cyclic or automatically cleared periodically?
Is it necessary to enable global maintenance for DB vacuum?
