makes sense - please open a bug to track. check would probably warn if

vdsm-gluster is to manage gluster storage, not consume gluster storage.
did you enable the gluster mode post installing the hosts?
(if you enabled it before installing them, or re-install[1] post
enabling gluster mode, it should have deployed vdsm-gluster as well)
[1] after moving hos to maintenance.

The host moving to Non-Operational state with error "Gluster command
failed..." is dependent on whether "Enable gluster service" is checked
on your cluster. This check indicates that you also want to manage
gluster storage provisioning on the nodes.
A recent change now checks that vdsm-gluster support is available for
such clusters. That's probably why you are seeing this error after update.

[Users] method "glusterHostsList" is not supported
by René Koch
Hi list,
My hosted engine is running again, so I want to start a new thread for
another issue with my setup.
I have a GlusterFS storage domain, which can be mounted from CLI without
problems. oVirt is 3.4 from ovirt-3.4.0-prerelease repository running on
CentOS 6.5 with latest updates (both OS and oVirt).
Both hosts, which act as hypervisors and GlusterFS nodes are in state
"Non Operational" in oVirt because "Gluster command [Non interactive
user] failed on server ovirt-host02.dmz.linuxland.at."
In engine.log I see the entry "glusterHostList is not supported"
(attached are the log entries when activating one of the hosts):
2014-03-03 18:17:11,764 ERROR
[org.ovirt.engine.core.vdsbroker.gluster.GlusterServersListVDSCommand]
(org.ovirt.thread.pool-6-thread-21) [6eee3cbd] Command
GlusterServersListVDSCommand(HostName = ovirt-host02.dmz.linuxland.at,
HostId = dd399eeb-f623-457a-9986-a7efc69010b2) execution failed.
Exception: VDSNetworkException: org.apache.xmlrpc.XmlRpcException: <type
'exceptions.Exception'>:method "glusterHostsList" is not supported
Can you give me a hint what this means and how I can activate my hosts
and storage again?
Thanks a lot!

[Users] Creating Logical Network issue - API
by Tejesh M
Hi ,
I'm trying to create Logical Network and assign it to cluster & want to
bond this to one of the Network Interface on Host. so that i can isolate my
VM from other networks.
The issue is even if i set Cluster while creating Logical Network, it is
not setting the cluster. In Web Admin it is in unset state.
Also, let me know how do i bind this Logical network on Host Interface.
*Java code:*
Network nw1=new Network();
VLAN vlan = new VLAN();
vlan.setId(2000);
nw1.setVlan(vlan);
IP ip = new IP();
ip.setAddress("192.168.1.151");
ip.setGateway("192.168.1.1");
ip.setNetmask("255.255.255.0");
nw1.setIp(ip);
nw1.setName("apiNetwork");
nw1.setDataCenter(api.getDataCenters().get("testDC"));
nw1.setCluster(api.getClusters().get("testCluster"));
org.ovirt.engine.sdk.decorators.Network nw2 =
api.getNetworks().add(nw1);

[Users] help requested

hey,
i want to study how ovirt implements the ISCSI protocol for disk access in
SANs, i want to study the source code files.
from where can i get them?
am thinking of implementing the aoe protocol.
also can i get help on how such plugins are made for ovirt, which files
need to be changed, and procedure to test the plugin by building the engine.

[Users] hosted engine setup (network)
by René Koch
Hi,
During hosted engine setup I faced issues with network configuration on
my CentOS 6.5 hosts:
My network setup was the following which doesn't work with hosted engine
setup:
- eth0.200 (VLAN tag 200) should become ovirtmgmt interface
- GATEWAY is in /etc/sysconfig/network and not in ifcfg-eth0.200
The following errors occured:
014-02-25 15:42:31 INFO
otopi.plugins.ovirt_hosted_engine_setup.network.bridge bridge._misc:189
Configuring the management bridge
2014-02-25 15:42:31 DEBUG

line 231, in _misc
'gateway=%s' % caps['cfg']['GATEWAY'],
KeyError: 'GATEWAY'
This can be solved by setting GATEWAY in ifcfg-eth* file instead of
/etc/sysconfig/network
Next, VLAN tagged interfaces don't work:
2014-02-25 15:35:20 INFO
otopi.plugins.ovirt_hosted_engine_setup.network.bridge bridge._misc:189
Configuring the management bridge

line 194, in _misc
].s.getVdsCapabilities()['info']['nics'][nics]
KeyError: 'eth0.200'
So I had to do the following:
- Set switch port to untagged for this VLAN
- Configure eth0 instead of eth0.200
- Run hosted engine setup
- Configure VLAN for ovirtmgmt in oVirt (which surprisingly worked for
an active interface)
- Configure VLAN tagging on hosts
- Reconfigure switch ports
- Sync networks in oVirt network setup tab
As this was a real pain to do I would love to see support for VLAN
tagging in hosted engine setup :)
Shall I open bug reports for these 2 issues or are they already known?

This means you have 3 semaphore sets, of one semaphore each.

Also the rest is moderate usage.

So you are far from the maxima (250 per set, 32000 total, 128 sets).

See e.g. http://man7.org/linux/man-pages/man5/proc.5.html
Is the above on a node? engine? both nodes are similar? If so, that's
not the reason for the "no space left on device".
If this error is reproducible, you can try to find the process that this
happens to (perhaps libvirtd, vdsmd, or the hosted-engine ha daemon) and do:
strace -f -o /tmp/trace1 -tt -s 512 -p PID
where PID is the pid of that process, then search /tmp/trace1 for 'no space
left on device' and see the exact call that failed.

Hi René,

Then I guess the traceback is my fault...
See http://gerrit.ovirt.org/#/c/25269/ for the fix. I will try to get it into the soonest release possible.

Me neither. Is everything Read-Write? Read-Only FS might report no space left as well in some cases. Other than that, I do not know.
