Re: [Users] New user to oVirt, and I haz a sad so far...

[Willard Dennis]

Aha!
"Host  does not comply with the cluster Default networks, the 
following networks are missing on host: 'ovirtmgmt' "
 
What must I do to correct this? I do not remember reading about having to do 
something like this in the docs... Also, the node is on a different network 
that the engine, not sure if this matters or not (the two network do have 
connectivity to each other thru a router.)
 
Thanks,
Will

[Users] Error when trying to create a new ISO storage domain

[Willard Dennis]

Hi all,
I am trying to define a new ISO storage domain. I go to System > Storage, click 
on the "New Domain" link, and fill in the requisite fields. "Domain Function / 
Storage Type" drop is set to "ISO / NFS", and I verified that I have the proper 
NFS path to the export on the NFS server I want to use. However, when I click 
the "OK" button, I am getting the following popup:

-Error while executing action Add Storage Connection: Permission settings 
on the specified path do not allow access to the storage.Verify permission 
settings on the specified storage path.-
I have verified that I can manually mount the NFS filesystem on the host 
defined in the "Use Host" drop [as root], and I have looked in 
/var/log/messages (on the mounting host, as well as the NFS server, and do not 
see any errors... Please not that the NFS export is a pre-existing share on the 
NFS server, and does contain pre-existing data (ISOs, etc.)
How can I debug this? ___

The share is on a Illumos (nee OpenSolaris) box, and uses ZFS's NFS 
implementation. Here is the output of the "share" command (i.e. exportfs) for 
this share:
-@storage/ovir  /volumes/storage/ovirt-isos   anon=36,sec=none,rw   ""
I did change the NFS mount options (added the "anon=36", and changed the "sec=" 
option from "sys to "none"), and now I'm getting a slightly different error:
-Error while executing action Add Storage Connection: Problem while trying 
to mount target-
Any way to get more info on what exactly the propblem is??

Re: [Users] Error when trying to create a new ISO storage domain

[Willard Dennis]

I am still trying to resolve this issue. I found the "Troubleshooting NFS 
Storage Issues" page, and have a few questions regarding the troubleshooting 
steps contained therein...
1) In the "Permissions" section, there's a suggestion under the "SELinux" 
subsection to "su - vdsm -s /bin/bash" and then try to mount the target NFS 
share under a temp mountpoint. However, the mount command is only usable as 
'root', right? If this can indeed be done, please let me know how (and I will 
update the wiki page...)
2) In the "nfs-check program" section, it says to run the Python script passing 
the the target NFS share path as a parameter. However, it does not indicate 
where to run the script -- on the engine, or on a node? (When I ran it on a 
node, it gives the output: return = 32 error mount.nfs: access denied by server 
while mounting stordevfs.nec-labs.com:/volumes/storage/ovirt-isos)

Just needed a clue where to look, thanks :)
I see that the mount cmd is being invoked with sudo, and that's how it works 
for the user vdsm --/usr/bin/sudo -n /bin/mount -t nfs -o 
soft,nosharecache,timeo=600,retrans=6,nfsvers=3 
stordevfs.nec-labs.com:/volumes/storage/ovirt-isos 
/rhev/data-center/mnt/stordevfs.nec-labs.com:_volumes_storage_ovirt-isos
And then the resulting error I'm getting:MountError: (32, ';mount.nfs: access 
denied by server while mounting 
stordevfs.nec-labs.com:/volumes/storage/ovirt-isos\n')
...which correlates with the output of the nfs-check.py script.
So, I will have to debug on the Illumos side as to why I don't seem to have the 
needed perm's; but, in the meantime, I did set up a NFS share on a CentOS 6.4 
box I have available, following directions on  
http://www.ovirt.org/Troubleshooting_NFS_Storage_Issues , and it does work fine 
from there. 
Thanks for your assistance!

[ovirt-users] Planning out oVirt Self-Hosted Engine on Gluster (oVirt 3.6.x / Gluster 3.7.5)

[Willard Dennis]

Hi all,

Back to trying out the latest oVirt with latest Gluster, and wanting to do a 
self-hosted Engine setup. I am reading the instructions I found on the 
following pages:

http://www.ovirt.org/Features/Self_Hosted_Engine_Gluster_Support 


http://www.ovirt.org/QA:TestCase_Hosted_Engine_External_Gluster_Support 


I have the requisite Gluster volume all ready to go:

[root@ovirt-node-01 ~]# gluster volume info engine

Volume Name: engine
Type: Distributed-Replicate
Volume ID: 974c9da4-b236-4fc1-b26a-645f14601db8

cluster.eager-lock: enable
performance.stat-prefetch: off
performance.io-cache: off
performance.read-ahead: off
performance.quick-read: off

The one question I have is, should it be mounted or not? I currently do have it 
mounted on each host (example off one of my oVirt hosts):

localhost:/engine  1.9T   65M  1.9T   1% /data/ovirt/engine

Will this interfere with the running of "hosted-engine —deploy”? Kindly advise.

[ovirt-users] Problem with hosted engine setup - vsdmd does not start

[Willard Dennis]

Hi all,

Tried to run the hosted engine setup, got:
[ ERROR ] Failed to execute stage 'Environment setup': [Errno 111] Connection 
refused

( full run output here: 
https://gist.githubusercontent.com/wdennis/4390042447354b2cb1c4/raw/c0f9127c676759b19b1d32a212c8c3694fac580e/hosted-engine-setup-output.txt
 

 )

Looked at the setup log file referenced in the output, saw this traceback in it 
that also referenced the Error 111:
https://gist.githubusercontent.com/wdennis/4390042447354b2cb1c4/raw/c0f9127c676759b19b1d32a212c8c3694fac580e/configurevm-py_error.txt
 


I diagnosed it (Google ftw) and saw that it was likely a vdsmd problem; sure 
enough, when I did a 'systemctl status vdsmd’ I saw that it was in error state -
Process: 28163 ExecStart=/usr/share/vdsm/daemonAdapter -0 /dev/null -1 
/dev/null -2 /dev/null /usr/share/vdsm/vdsm (code=exited, status=1/FAILURE)

( full status output here:

 )

Does anyone know how I can troubleshoot and fix the VDSM daemon start process?

Thanks,
Will

Re: [ovirt-users] Problem with hosted engine setup - vsdmd does not start

[Willard Dennis]

Any thoughts on this issue?? This is holding up my project (oVirt hosted engine 
install won’t proceed if VDSM service is not running…)  Why am I even having 
such problems with the VDSM service? It’s on a vanilla CentOS 7 install…

Thanks

Re: [ovirt-users] Problem with hosted engine setup - vsdmd does not start

[Willard Dennis]

OK, should not have used the term “vanilla” I guess… I have customized the OS 
to fit into my environment (not so much with kickstart, mostly via Ansible) and 
of course have installed Gluster 3.7 and configured volumes for the engine and 
VM storage. So it’s not like it’s running on a completely stock CentOS 7 
install (that would be basically unusable for me…)

Doing a complete reinstall would be many hours of work (already have done that 
once to reconfigure Gluster) so not really interested in doing that…

I’d love to continue debugging; just frustrated that everything done so far has 
not worked (read thread for details…) and we cannot get the vdsmd service to 
run… I do very much appreciate the assistance of all the RHAT folks who have 
responded to this thread, you are my only hope of getting this stuff running, 
as I’m not an oVirt expert by far

So, the message "vdsm user could not manage to run sudo operation: (stderr:

configuration” — what would have to be set in sudden rules to allow this to 
succeed?

[ovirt-users] Hosted engine setup using Gluster - what is proper param's for the storage domain names?

[Willard Dennis]

Hi all,

Doing the hosted engine setup on Gluster; am at the point of configuring the 
storage domain / datacenter names, and not sure of what my best move is here… 
Here’s what I’m seeing:

——
  --== STORAGE CONFIGURATION ==--

  During customization use CTRL-D to abort.
  Please specify the storage you would like to use (glusterfs, iscsi, 
fc, nfs3, nfs4)[nfs3]: glusterfs
[ INFO  ] Please note that Replica 3 support is required for the shared storage.
  Please specify the full shared storage connection path to use 
(example: host:/path): localhost:/engine
[WARNING] Due to several bugs in mount.glusterfs the validation of GlusterFS 
share cannot be reliable.
[ INFO  ] GlusterFS replica 3 Volume detected
[ INFO  ] Installing on first host
  Please provide storage domain name. [hosted_storage]:
  Local storage datacenter name is an internal name
  and currently will not be shown in engine's admin UI.
  Please enter local datacenter name [hosted_datacenter]:
——

Concerned about the "Local storage datacenter name is an internal name and 
currently will not be shown in engine's admin UI” message… I want to use a 
second distributed Gluster volume (name = “vmdata”) for VM storage if I can, 
and don’t want to mess up the install… What should I consider when setting 
names for the storage domain name and local datacenter names?

Thanks,
Will

[ovirt-users] Problem with 3.5.1 hosted engine setup

Hi all,

I’m trying to get a hosted engine set up on a CentOS 7.1 box, per the 
instructions found at 
http://community.redhat.com/blog/2014/10/up-and-running-with-ovirt-3-5/ 


When I run the ‘hosted-engine —deploy’ step, I’m getting the following output…

Looking at the log file, I see the following traceback:
https://gist.github.com/wdennis/4e4de8413cf2dd1a3c6b 


Can anyone tell me what exactly is failing, and how I might fix it?
