Hi Milosz,

I have used original unpack_command as you suggested but still as read only image its get stuck in the overlay unpack. Below I am showing the context and transfer_overlay session that I used for that. And could you please share the sample staging job definition that you used with job context ?

Sure: https://lava.infra.foundries.io/scheduler/job/17490

The strange thing about your job is there is no command sent over serial to start overlay decompression. Like here: https://lava.infra.foundries.io/scheduler/job/17490#L3404

This one uses a slightly different overlay path, but it still works.

Best Regars, Milosz

context: arch: x86 lava_test_results_dir: "/etc/lava-%s"

transfer_overlay:
  download_command: sleep 10; cd /tmp; wget
  unpack_command: tar -C / -xzf

Status : The job is get stuck in the overlay unpack.

Hi Milosz,

Thanks for your reply. I have tried below scenario and could able to succeed with the overlay download in a different directory. But the unpack is still not taking in the "/" directory as I am having the read only image. So we have tried in the /etc directory cause its writable and I am showing the test job definition snippet below which I used.

context: lava_test_results_dir: "/etc/lava-%s"

Then in the boot/transfer_overlay: transfer_overlay: download_command: cd /etc ; wget unpack_command: tar -C /etc -xzf

Result status: The test job got stuck after the overlay download and did not proceed with the unpack.

Did you try the job with the original unpack_command? The overlay is prepared on the dispatcher with the full absolute path to unpack. So with the job as you posted you'll end up with your files in /etc/etc/lava-0 ... This is not what LAVA expects and that's why you're getting stuck.

Best Regards, Milosz

This is what I have in my jobs and it works for me. Context should include lava_test_results_dir

context: lava_test_results_dir: "/home/fio/lava-%s"

Then in the boot/transfer_overlay: transfer_overlay: download_command: cd /tmp ; wget unpack_command: tar -C / -xzf

Hope this helps.

Sarah,

It's hard to debug without the testjob definition. Could you post this here?

Best Regards,

Hi Team,

Any solution for the issue that I pointed here ? I tried below change as well

1. Changed the source code

“/usr/lib/python3/dist-packages/lava_dispatcher/deployment_data.py” with “/var/lava-%s “ custom path

debian = {

"TESTER_PS1": r"linaro-test [rc=$(echo \$?)]# ",

"TESTER_PS1_PATTERN": r"linaro-test \[rc=(\d+)\]# ",

"TESTER_PS1_INCLUDES_RC": True,

"boot_cmds": "boot_cmds",

"line_separator": "\n",

# for lava-test-shell

"distro": "debian",

"tar_flags": "--warning no-timestamp",

"lava_test_sh_cmd": "/bin/bash",

"lava_test_dir": "/var/lava-%s",

"lava_test_results_part_attr": "root_part",

"lava_test_results_dir": "/var/lava-%s",

"lava_test_shell_file": "~/.bashrc",

}

Status of the change : The overlay unpack is not happening in the specific directory that we applied to lava_test_dir and lava_test_results_dir.

I would appreciate it if you could send the solution of the issue that I raised here.

Regards,

Sarath P T

Hi Team,

Facing an issue while unpack the overlay in some custom location other than “/” directory. From the LAVA linaro documentation I came to know that the -C / command to tar is essential or the test shell will not be able to start. Below are the issues that I am facing because of this.

My / directory is a read only one and I want it in some /etc or /var. The LAVA job is getting stuck while doing the unpack with the command below in job definition.

transfer_overlay:

  download_command: cd /tmp; wget

  unpack_command: tar -C /tmp -xzf

Below I am attaching the test log from LAVA.

How we can solve the read only filesystem image issue for unpacking the overlay other than “/” directory ?

Regards, Sarath P T
