Nagendra,
This is a bit of missing documentation. You can change this in job context. Context is set on the top level of yaml job definition. Example below:
context: lava_test_results_dir: "/var/volataile/lava-%s"
You'll need to experiment with this a bit to make sure that the paths are correct. Hope it helps.
Best Regards, Milosz

Hi Milosz,
Hope you are doing well !!. After a couple of changes applied to ethernet /sd-boot driver operations of my kernel, now I am able to run the lava-test-shell method and am able to run the test-suite.
But as I said in the earlier mail chain, mine roots is read only @ / directory and /var/volatile having read/write . But as per lava-test-shell all the commands pointed to /(lava-test-job-id). Can you please suggest to me the changes to run from /var/volatile instead / directory. when i check the framework code path is getting from the following
self.scripts_to_copy = sorted( glob.glob(os.path.join(self.lava_test_dir, "lava-*")) )
lava_test_results_dir = self.get_constant("lava_test_results_dir", "posix")How to redirect to /var/volatile !!.
Thanks

Nagendra,
I don't think NFS deployment in LAVA works as you expect. It's meant for boards that use the whole rootfs mounted from NFS, not just part of it. As far as I'm aware it's mostly used for deploying from TFTP (kernel, ramdisk, dtb) where rootfs is required: https://master.lavasoftware.org/static/docs/v2/actions-deploy.html#index-23.

Hi Milosz,
Fortunately, I am able to run NFS client services on DUT and was able to access mount directories(created one directory under /home/) of the worker(configured as NFS server) manually. This process I have tried without LAVA.
In the earlier mail chain, you have shared the transfer_overlay method as below which can be supported for udhcpc. Can you please point me to the job definition for nfs mount option. That would be a great help !!
- boot: ... transfer_overlay: download_command: udhcpc;cd /home ; wget unpack_command: tar -C -xzf
Note: As my rootfs file system is read only access and limited RAM space(2.5 MB) available I can't use udhcpc/tar but I am assuming the NFS mount option will work here.
thanks

Nagendra,
It really sounds like a missing feature, doesn't it? It should be possible to manually add overlay to your build (or at least have means for doing it). @Remi, @Antonio, @Stevan - how much effort would it take to add such feature? The use case is:
- download your images using 'downloads'
- prepare overlay
- expose overlay path so user can add overlay to the image(s) in
dockerize postprocess. I would gladly use it as downloading and decompressing overlay takes ages on some of my boards.

Hi Milosz,
I have tried Interactive test method for small test suite (5-10 testcases). And true, Interactive test can't generate overlay. But my actual suite contains more than 200 testcases. And for each testcase execution have to invoke the command in job description as a name: command: in interactive test module looks tricky for me to maintain . that's why i am looking for alternate solution!!.
Thanks Milosz for your time and support :)

I haven't used it for a long time so I don't remember exactly how to do that, sorry :(

hmm, have you tried it? I don't think interactive test generates an overlay as it's executed from the worker (over serial) rather than from shell.
