[ovirt-users] [hosted-engine] Error creating a glusterfs storage domain

[Wee Sritippho]

Hi,

Wow. How dumb of me. I just realized that I answered "Yes" in this 
configuration question:

iptables was detected on your computer, do you wish setup to configure 
it? (Yes, No)[Yes]:

So the hosted-engine setup configure my empty iptables to allow just 
some necessary port (excluding glusterfs)

I solved this by editing /etc/sysconfig/iptables to:

# oVirt+glusterfs firewall configuration.
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
# vdsm
-A INPUT -p tcp --dport 54321 -j ACCEPT
# rpc.statd
-A INPUT -p tcp --dport 111 -j ACCEPT
-A INPUT -p udp --dport 111 -j ACCEPT
# SSH
-A INPUT -p tcp --dport 22 -j ACCEPT
# snmp
-A INPUT -p udp --dport 161 -j ACCEPT
# libvirt tls
-A INPUT -p tcp --dport 16514 -j ACCEPT
# serial consoles
-A INPUT -p tcp -m multiport --dports 2223 -j ACCEPT
# guest consoles
-A INPUT -p tcp -m multiport --dports 5900:6923 -j ACCEPT
# migration
-A INPUT -p tcp -m multiport --dports 49152:49216 -j ACCEPT
# glusterfs
-A INPUT -p tcp --dport 24007:24008 -j ACCEPT
-A INPUT -p tcp --dport 24007:24008 -j ACCEPT
-A INPUT -p tcp --dport 38465:38467 -j ACCEPT
# nfs
-A INPUT -p tcp --dport 2049 -j ACCEPT

# Reject any other input traffic
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -m physdev ! --physdev-is-bridged -j REJECT --reject-with 
icmp-host-prohibited
COMMIT

Then restarted iptables and run 'hosted-engine --deploy again'. This 
time, I made sure to answer "No" when the setup asked me if it should 
alter iptables or not. The deployment was success, although with some 
errors:

[ ERROR ] The VDSM host was found in a failed state. Please check engine 
and bootstrap installation logs.
[ ERROR ] Unable to add hosted_engine_1 to the manager

I were somehow able to solve them by manually SSH from the engine to the 
host, so that the host's key fingerprint was added to the engine's 
known_hosts. Then I logged into the engine's web UI and manually 
reinstall hosted_engine_1 with the "Automatically configure host 
firewall" option deselected (since I already included all of its 
configuration in my iptables file).

I also set the virt group profile on the storage domain's volume as you 
suggested.

Thank you very much for guiding me.
