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..
Thanks for raising this.
On adding the host there is an error about vdsm-hook-nestedvt which I cannot interprete, maybe someone else can do.
In vdsm.log I noticed a strange behavior of setupNetworks, can you please share the corresponding supervdsm.log, too?
Cheers
