Hello OpenNebula Team,



I am having an issue adding a new host to OpenNebula. I hope someone can
help me.

Hi Manuel,

According to the log, can you please verify that the script "/var/tmp/one/im/run_probes":


1) is present on the newly added node

2) is accessible by oneadmin user

3) is executable by oneadmin user

Cheers,

Ondra

Thanks a lot for your answer.

Here my answer

1) is present on the newly added node

The script is present in the new node

***@km1:/var/tmp/one/im/kvm.d$ ls -l /var/tmp/one/im/run_probes
-rwxr-xr-x 1 oneadmin oneadmin 1863 Dec 22 13:16
/var/tmp/one/im/run_probes
***@kvm1:/var/tmp/one/im/kvm.d$

2) is accessible by oneadmin user

the oneadmin user is the owner
3) is executable by oneadmin user

It can execute the script

This is the output

***@kvm1:/var/tmp/one/im/kvm.d$ /var/tmp/one/im/run_probes kvm
/var/lib/one//datastores 4124 20 49 kvm1

The error from collectd-client.rb means that the system variable SSH_CLIENT is unset.

You can verify this by connecting to the node via ssh from the opennebula fronend as ‘oneadmin’ user and running the ‘env’ command (the same way as opennebula does).

Normally sshd should set this env variable when opening the loginshell. I don’t know what shell you use for oneadmin, but you should check that its rc scripts are not clearing up the SSH_CLIENT variable or something like that.

Here’s a bit outdated discussion, but the problem seems similar: http://www.gossamer-threads.com/lists/openssh/dev/8359

Ondra

Hello,

Thanks for your support.

I have fixed the issue with the SSH_CLIENT variable. Now it is available,
but the issue still happens.

The error from collectd-client.rb means that the system variable SSH_CLIENT is unset.
You can verify this by connecting to the node via ssh from the opennebula
fronend as ‘oneadmin’ user and running the ‘env’ command (the same way as
opennebula does).
Normally sshd should set this env variable when opening the loginshell. I
don’t know what shell you use for oneadmin, but you should check that its
rc scripts are not clearing up the SSH_CLIENT variable or something like
that.

Thanks a lot for your answer.
Here my answer
1) is present on the newly added node
The script is present in the new node
-rwxr-xr-x 1 oneadmin oneadmin 1863 Dec 22 13:16
/var/tmp/one/im/run_probes
2) is accessible by oneadmin user
the oneadmin user is the owner
3) is executable by oneadmin user
It can execute the script
This is the output
/var/lib/one//datastores 4124 20 49 kvm1
./collectd-client.rb:122:in `<main>': undefined method `split' for
nil:NilClass (NoMethodError)

Hi Manuel,
According to the log, can you please verify that the script
1) is present on the newly added node
2) is accessible by oneadmin user
3) is executable by oneadmin user

Hi Manuel,

apologies for the delay. This is one of those complex issues that are hard
to debug. Can you follow the directions I explained in the link you sent
me? I can't think of an easier way to debug this...

cheers,
Jaime

Hello Jaime,
I found this issue very very similar to my issue. Can you help me please ?
Hello,

Thanks for your support.
I have fixed the issue with the SSH_CLIENT variable. Now it is available,
