System unavailable: Various linux aarch64 machines

[adamfarley]

• Please put the system name in the title of this issue.

  • test-alibaba-ubuntu1804-armv8-1
  • test-alibaba-ubuntu1804-armv8-2
  • test-docker-centos8-armv8-1
  • test-docker-debian11-armv8-1

• Link to any log file showing the problem:

  • The log files for the machines show the issues, though I cannot access these myself to provide the link.

• Please describe the issue:
  Two of these machines appear to have connection issues. A link cannot be established between Jenkins and them.

The other two machines see the Java agent die quickly after re-enabling. Error code 126 (command found, but failed anyway).

One theory is that these machines are out of / low on memory. Can they be restarted please?

If this does not fix the issue, perhaps they should be re-initialised from scratch (re-provisioned/re-ansibled).

These 2 are back online following an issue whereby the dockerhost became unreachable.

test-docker-centos8-armv8-1
test-docker-debian11-armv8-1

I think the host key for these 2 servers has changed, and so Jenkins cant connect to them..
test-alibaba-ubuntu1804-armv8-1
test-alibaba-ubuntu1804-armv8-2

I don't have permissions to correct this.

@Haroon-Khel do you have access or any contact for these 2 alibaba machines...?

@Haroon-Khel Did you hear back from Alibaba about the machines they're hosting for us?

[sxa]

I've removed the alibaba machines from jenkins. They can be added again if we obtain replacements.

Monitoring in place, closing so new issues can be raised as required.
