Can't add freshly installed node.. host has no default route
by Giorgio Biacchi 13 May '20

13 May '20

Hi list, I've spent a couple of days trying to understand why this was happening... For the installation I have a well tested installation server with a custom kickstart file to setup ssh keys and custom hooks for infiniband and I'm installing Ovirt Node 4.3.9 via pxe, this is particularly useful when I have to install a bunch of blades at once.. In the past I had no issues and all was working like a charm until now when some hardware failed and I had to replace it. As expected I have no issues in the node installation process.. the troubles begins when I try to add the node, installation fails and in the UI I have an exclamation mark with the message "Host has no default route." but I can ping and do ssh to the host from the manager.. the problem is somewhere else in the communication between the engine and vdsmd preventing the engine to refresh the host capabilities. So from the engine I tried: [root@manager ~]# openssl s_client -connect 172.20.22.78:54321 CONNECTED(00000003) --- Certificate chain 0 s:/CN=cn128.lagrange.di.unimi.it/O=VDSM Certificate i:/CN=VDSM Certificate Authority 1 s:/CN=VDSM Certificate Authority i:/CN=VDSM Certificate Authority --- The host has still the self signed vdsm certificate.. and on the host in vdsm.log I find: 2020-05-11 09:52:25,433+0000 ERROR (Reactor thread) [ProtocolDetector.SSLHandshakeDispatcher] ssl handshake: SSLError, address: ::ffff:159.149.129.220 (sslutils:264) So I tried to enroll the certificate from the UI and from the events tab I sow the enrolling was successful but: [root@manager ~]# openssl s_client -connect 172.20.22.78:54321 140084336994192:error:140790E5:SSL routines:ssl23_write:ssl handshake failure:s23_lib.c:177: CONNECTED(00000003) --- no peer certificate available --- there's still some issue with the certificates.. so on the host again: [root@cn128 vdsm]# find /etc/pki/vdsm/ -type f -cmin -10| xargs ls -l -rw-------. 1 root kvm 1424 May 11 09:56 /etc/pki/vdsm/certs/cacert.pem -rw-------. 1 root kvm 5108 May 11 09:57 /etc/pki/vdsm/certs/vdsmcert.pem -r--r-----. 1 root kvm 1704 May 11 09:56 /etc/pki/vdsm/keys/vdsmkey.pem -rw-r--r--. 1 root root 1424 May 11 09:57 /etc/pki/vdsm/libvirt-spice/ca-cert.pem -rw-r--r--. 1 root root 5108 May 11 09:57 /etc/pki/vdsm/libvirt-spice/server-cert.pem -r--r-----. 1 root root 1704 May 11 09:56 /etc/pki/vdsm/libvirt-spice/server-key.pem It seems that cacert.pem and vdsmcert.pem have wrong permissions.. let's try to fix it.. [root@cn128 vdsm]# chown 36:36 /etc/pki/vdsm/certs/cacert.pem /etc/pki/vdsm/certs/vdsmcert.pem And now: [root@manager ~]# openssl s_client -connect 172.20.22.78:54321| less CONNECTED(00000003) --- Certificate chain 0 s:/O=lagrange.di.unimi.it/CN=172.20.22.78 i:/C=US/O=lagrange.di.unimi.it/CN=cn305.lagrange.di.unimi.it.35941 1 s:/C=US/O=lagrange.di.unimi.it/CN=cn305.lagrange.di.unimi.it.35941 i:/C=US/O=lagrange.di.unimi.it/CN=cn305.lagrange.di.unimi.it.35941 --- Now I can finally refresh the host capabilities and setup the host networks.. In attachment all the relevant logs, I don't know if I've found some bug.. this is the first time i had so many troubles adding a new host.. so I decided to share my experience with the list..

Any official support list of SAS RAID controller?
by hkexdong＠yahoo.com.hk 13 May '20

13 May '20

I am not going to use those servers from HP, IBM, etc. My computer is desktop level and plan to insert a PCI-E SAS RAID controller card, that use to connect to an external SAN storage (https://www.areca.com.tw/products/storage-8042.html) I afraid I might buy the wrong RAID card that oVirt can't recognize. Is there any official support list of SAS RAID controller?

I run tail -f engine.log and tail -f server.log, but it remains still. This is the same case with the httpd logs. If you don't see anything in any of the httpd logs, it means the request that your browser sent didn't arrive to httpd. Perhaps indeed you have some networking issue? Can you ping/ssh/etc from inside the engine some machine outside (other than the host it's on)? The other way around - from the engine vm to outside? If not, you should first fix that. That said, I'd not expect a 503 in that case, but a timeout on your browser. So either you didn't check the right log file (or there is some other problem, such as full disk, iptables, whatever) or some other machine returns you 503. You can also check with a sniffer (tcpdump) on the engine machine to see if it gets traffic, e.g. tcpdump -i any port 80 or port 443 > > > > I checked the status of the engine from my node, and it displays the below: > > > > [root@jb2-client-node01 ~]# hosted-engine --vm-status > > > > > > !!

When attaching complete logs (thanks for that!), please state the exact time you tried to do something that failed (access the web ui, in this case). Your attached logs have several different ERRORs, which might be due to unrelated things, and it's hard to tell where to look first. Once found, going backwards to try to find the root cause is usually easier. 2. Please check/share also httpd logs, and also /etc/httpd/conf.d - you can compare it with a fresh engine you can setup on some test vm somewhere, it should be mostly the same. 3.

Not necessarily everything, but even if you ask to remove only something specific, it does more than that.

When attaching complete logs (thanks for that!), please state the exact time you tried to do something that failed (access the web ui, in this case). Your attached logs have several different ERRORs, which might be due to unrelated things, and it's hard to tell where to look first. Once found, going backwards to try to find the root cause is usually easier. 2. Please check/share also httpd logs, and also /etc/httpd/conf.d - you can compare it with a fresh engine you can setup on some test vm somewhere, it should be mostly the same. 3. Also please check/share engine-setup logs, at /var/log/ovirt-engine/setup. You can search there for httpd or apache. 4. I have a feeling, just a guess, that you are missing /etc/httpd/conf.d/z-ovirt-engine-proxy.conf . Not sure what might have caused that. setup after cleanup should have created it.

503 Service Unavailable
by Anton Louw 12 May '20

12 May '20

Hi All, So due to some bad decisions etc. I have accidently removed the hosted engine setup by running engine-cleanup. I initially just wanted to remove the websocket proxy, and as advised by an article, this can be done by running engine-cleanup. Obviously this was not the case, and it removed everything. I at least had a backup that I took, so I restored the backup to the engine, and ran engine-setup. Everything runs fine, but when I try and access the webUI, I get an error: "503 Service Unavailable" "No server is available to handle this request" I have checked the ovirt-engine service, and it is running, as well as the httpd service. I have also attached the engine log as well as the server log. Does anybody have any idea where I can check, or perhaps I missed something. Thank you Anton Louw Cloud Engineer: Storage and Virtualization ______________________________________ D: 087 805 1572 | M: N/A A: Rutherford Estate, 1 Scott Street, Waverley, Johannesburg anton.louw(a)voxtelecom.co.za www.vox.co.za

oVirt engine / node & snmp
by Andrei Verovski 12 May '20

12 May '20

Hi, oVirt node seems to run snmp by defeult, “service snmpd status” returns some data. I’m going to connect all servers to LibreNMS, and it requires custom snmp options. What options I should keep in oVirt node default nsmp.conf? Or I may just fully overwrite this file with my own? Please note my oVirt node installed manually on CentOS, I don’t use node DVD image from oVirt project. with best regards Thanks in advance. Andrei

Upgrade scenario to 4.4 for HCI Gluster
by Gianluca Cecchi 11 May '20

11 May '20

Hello, I saw from some mails in the list that the approach for upgrading from 4.3 to 4.4 will be similar to the 3.6 => 4.0 one. Reading the RHV 4.0 Self Hosted Engine Guide it seems it was necessary to have a second host, going through this: 5.4. Upgrading a RHEV-H-Based Self-Hosted Engine Environment https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.0/ht… and also https://www.ovirt.org/develop/release-management/features/sla/hosted-engine… upgrade process involved: - set global ha maintenance - install a new host (and set it as on hosted engine one) - migrate engine VM to this host and set the host as the SPM - create a backup with engine-backup, verify its contents and copy to the host in some directory - run the upgrade utility on the host to update the engine VM hosted-engine --upgrade-appliance this will create a backup floating disk of the engine vm disk for rollback purposes and override the existing engine disk with a new one where to deploy the new engine version applying also the restore from the engine-backup --> what are requirements for 4.4 engine VM and so free storage to have on engine storage domain? The engine-setup will be automatically executed on the new version engine VM - exit from global maintenance - update remaining hosts Is the above procedure the correct one that I can test on a 4.3.9 lab? The 3.6 -> 4.0 flow implied that a 4.0 host could run a 3.6 engine VM Because the backup disk operation is done by the current running engine itself. So it should be true also for 4.3 -> 4.4 and a 4.4. host should be able to run a 4.3 engine, correct? In case of single 4.3.9 ovirt-node-ng host HCI with Gluster, can I apply the upgrade in a similar way? Something like: - create engine-backup and copy over to the host - put host into global maintenace - shutdown all VMS, engine included - enable 4.4. repo - install new image-base 4.4 is this correct and I can use 4.3 and 4.4 image base versions or do I have to sort-of-scratch necessarily? because 4.3 host is based on el7 while 4.4 on el8... but perhaps on mage based system I have flexibility..? what version of gluster will it be applied? Incompatibilities with the current 4.3.9 one (version 6.8-1.el7) - reboot host - exit global maintenance and wait for engine vm to come up correctly - enter global maintenance again - run the upgrade utility on the host Or do I need at least temporarily a new server to use as the 4.4. host, or what will be the expected path? Thanks, Gianluca
