Missing step(s) after custom x509 certificates
by John Florian 24 Jun '18

24 Jun '18

I followed the docs at https://www.ovirt.org/documentation/admin-guide/appe-oVirt_and_SSL/ and all works well from the usual web portal. Went to test moVirt and ran into a snag. It wants to download the CA using http://fqdn/ovirt-engine/services/pki-resource?resource=ca-certificate&form…, but that's grabbing the old CA issued by the engine rather than my custom CA. What else needs to be changed? I'm sure I can finagle my way to a fix here by telling moVirt to use a custom URL or file, but this looks like a bug in the docs that would probably best be fixed. -- John Florian

disk performance findings
by william.dossett＠gmail.com 23 Jun '18

23 Jun '18

I have deployed a HCI environment several times now as I wanted to get some idea of disk performance with Gluster/ On a Dell R720 3 node cluster with H710 PERC controller and 8 x 2TB 7200 RPM SATA drives. My first test was with the 8 drives configured as H/W RAID 6 and I configured Gluster as RAID 6 - quite a lot of redundancy but that was just my first deployment Running IOMeter for 24 hours using all in one access specification I got 240 IOPs. Pretty good for SATA drives. I then broke the RAID and configured 8 virtual disks, one per physical and then deployed Gluster as JBOD - I am not sure how resilient that is, but I assume in a 3 node cluster failures to tolerate would be one. This gave me 267 IOPs. I don't know that much about the internals of Gluster, but when I first asked about this there didn't seem to be much knowledge of what configuration would be best for HCI. I plan to do more research and tests on this, but for what its worth for now, I am going down the JBOD route with no H/W RAID. Regards Bill

Restore and rename engine
by Staniforth, Paul 23 Jun '18

23 Jun '18

Hello, I have been trying to test our system by restoring from backup to a new machine and running ovirt-engine-rename, then engine-setup. I get to sent back to the main oVirt Web page from any of the portals, which has an Warning triangle saying the engine is initializing. and in the URL it has ovirt-engine/?error_description=server_error%3A+%2Fetc%2Fpki%2Fjava%2Fcacerts+(No+such+file+or+directory)&error=server_error The original machine had a certificate signed by an external authority. I tried putting back the link from apache-ca.pem to ca.pem, the original apache.key.nopass, websocket-proxy.key.nopass as well as hte key files. I upgraded from 4.1.9 to 4.2.3 and it says it is resigning the certificates but still fails. Regards, Paul S.

quick way to start glusterfs managed engine over?
by william.dossett＠gmail.com 23 Jun '18

23 Jun '18

I have successfully got glusterfs playbook to finish once and then my networking was wrong on the managed engine and on the hosts, so I started over. Now I can't seem to even get that far again. I completely reloaded the hosts, but that takes a while. Last time glusterfs failed right at the end with "host is not in 'Peer in Cluster' state" Redeploying fails as partitions already exist. I am deploying to /dev/sdb Is there a quick way to get /dev/sdb back into a state to redeploy to? I think I got there once by doing pvremove and gdisk zap gpt, but not sure if that worked or caused problem on the redeploy. Its very time consuming to start over from scratch, so would appreciate if there is any shortcut instead of reloading the OS. Thans Bill

Hello List 😊 I’m facing an issue regarding Self Hosted Engine appliance deployment on OVirt 4.2( tested on 4.2.2 and 4.2.3). During setup tool, I’m unable to mount a remote storage NFS / iSCSI. When I try to mount an NFS share: [ INFO ] TASK [Remove host-deploy configuration file] [ INFO ] changed: [localhost] Please specify the storage you would like to use (glusterfs, iscsi, fc, nfs)[nfs]: nfs Please specify the nfs version you would like to use (auto, v3, v4, v4_1)[auto]: xxxxxx:/YYYYYY [ ERROR ] Invalid value Please specify the nfs version you would like to use (auto, v3, v4, v4_1)[auto]: Please specify the full shared storage connection path to use (example: host:/path): xxxxxx:/YYYYYY If needed, specify additional mount options for the connection to the hosted-engine storagedomain []: [ INFO ] Creating Storage Domain [ INFO ] TASK [Gathering Facts] [ INFO ] ok: [localhost] [ INFO ] TASK [Check local VM dir stat] [ INFO ] ok: [localhost] [ INFO ] TASK [Enforce local VM dir existence] [ INFO ] skipping: [localhost] [ INFO ] TASK [include_tasks] [ INFO ] ok: [localhost] [ INFO ] TASK [Obtain SSO token using username/password credentials] [ INFO ] ok: [localhost] [ INFO ] TASK [Fetch host facts] [ INFO ] ok: [localhost] [ INFO ] TASK [Fetch cluster ID] [ INFO ] ok: [localhost] [ INFO ] TASK [Fetch cluster facts] [ INFO ] ok: [localhost] [ INFO ] TASK [Fetch Datacenter facts] [ INFO ] ok: [localhost] [ INFO ] TASK [Fetch Datacenter ID] [ INFO ] ok: [localhost] [ INFO ] TASK [Fetch Datacenter name] [ INFO ] ok: [localhost] [ INFO ] TASK [Add NFS storage domain] [ ERROR ] Verify permission settings on the specified storage path.]".

Ignore extra parameters in oVirt API
by Hari Prasanth Loganathan 22 Jun '18

22 Jun '18

Hi Team, I want to attach the disk using the oVIrt rest API, I use the version* 4.2* and completed my script. But when I downgrade my oVirt to lower version *4.1*, I get the following error. detail: 'For correct usage, see: https://X.X.99.84/ovirt-engine/api/v4/model#services/disk-attachments/metho…',\n reason: 'Request syntactically incorrect.',\n error: 'For correct usage, see: https://X.X.99.84/ovirt-engine/api/v4/model#services/disk-attachments/metho… ',\n *Reason*: I added an extra parameter called 'isSharable' which is not expected in this API. *So Is there a way to Ignore the extra parameters sent for oVirt API?* *Example :* *Expected :* *{* * "a" : "1"* *}* *I sent :* *{* * "a" : "1",* * "b" : "2"* *}* *My expectation is, Ignore the "b" and the API should work, Is there a flag in oVirt API which ignores the extra parameters? * Thanks, Hari
