Hello lava users, I have to deal with a board with a very limited storage size. Overall capacity is 64 MB, with about 30 MB remaining. This is a clear limitation for Lava usage. Hence my questions: * Is there a possibility to configure Lava tests installation on an external storage, such as an USB drive? * In Lava recent versions, is it possible to optimize the overlay tests structure? * Today, assuming that tests are stored in a git repo, for each test the complete repo is copied in each overlay * A balance has to be made between one git containing all the tests and one git per test (extreme configurations) * Is there a better way to manage this? In a ideal world, that would mean copy only what is needed and not more Thanks, have a nice day

Problem with https and WS_URL

by Philippe Mazet (OSS)

Hello, While testing 2020.10 with https enabled, we have noticed the following problem: In /etc/lava-dispatcher/lava-worker, if we set WS_URL="--ws-url http://<master's address>/ws/" (or do not this variable at all), we get the following error on worker: 2020-11-19 15:14:57,751 INFO PING => server SSL error in data received protocol: <asyncio.sslproto.SSLProtocol object at 0x7f9a0d704160> transport: <_SelectorSocketTransport fd=8 read=polling write=<idle, bufsize=0>> Traceback (most recent call last): File "/usr/lib/python3.7/asyncio/sslproto.py", line 526, in data_received ssldata, appdata = self._sslpipe.feed_ssldata(data) File "/usr/lib/python3.7/asyncio/sslproto.py", line 207, in feed_ssldata self._sslobj.unwrap() File "/usr/lib/python3.7/ssl.py", line 767, in unwrap return self._sslobj.shutdown() ssl.SSLError: [SSL: KRB5_S_INIT] application data after close notify (_ssl.c:2609) Still, even with those errors the worker is fully functional. Now, the only way to get rid of such errors is to explicitly specify the port, 8001: WS_URL="--ws-url http://<master's address>:8001/ws/" Have you experienced similar problems? Did we miss something on our setup? Thanks a lot, Philippe

Unable to change device health state without being admin

by Sebastien Haezebrouck

Hi, We used to set devices access permission using groups. So we would restrict access to a subset of devices to members of a specific group. When switching to lava 2020.10, it seems the permission to change a device does not allow to change device health state anymore. This used to be possible in previous version, and was very convenient for maintenance. With 2020.10 it seems only a lava admin is allowed to change a device health. Is it the expected behavior ? Did I miss an option somewhere ? A bit more details: All our devices are set to: * “device owner”->”Group with physical access” -> our_group. * “group device permissions”->”lava_sched_app |device | Can change device” -> “Group” -> our_group. * I intentionally did not give any specific permission to the “our_group” group, like “Can change device”, since it would allow members of this group to change any devices. Access control has to work both ways 😊 Kind regards, Seb

Issue with DUT reboot command with uuu boot method (ssh login)

by Anand, Ravi

Hello All, I am currently facing one issue where I have to execute reboot (soft reboot) command in DUT. But after executing reboot command , target is getting rebooted and lava job get stuck at login prompt. To overcome this I have inserted boot section with auto_login (waiting for login prompt to pass username & password). But with this scenario, just after reboot command , target is getting rebooted (Hard reset) by PDU. Can somebody help me on this. I don't want DUT to get hard reset by PDU. Expectation is like just after reboot command, wait for login prompt and then proceed it with another set of commands. Attached both scenario sample pipeline definitions for reference. Regards, Ravi Anand

Re: [Lava-users] Subject: Issue with DUT reboot command with uuu boot

by koti koti

Hi Ravi Anand, Can you try using "Method: minimal" ? Reference: https://docs.lavasoftware.org/lava/actions-boot.html#minimal) Example: ####### " actions: - boot: timeout: minutes: 2 method: minimal " Note: 1. You can mention your custom soft reboot command using the string "soft_reboot" or "{% set soft_reboot_command = 'reset' %}" in corresponding files.

Worker/master version mismatch

by Philippe Mazet (OSS)

Hi All, Since 2020.09 it appears that workers using a version different than the master are refusing to start. Would it be possible to relax this constraint? With workers spread all over the world in different places, it is hard to synchronize master and slaves upgrades. Also, we have always run with workers versions <= master version, without a single problem. So it would be great to allow version mismatch, and maybe print a simple warning when version differs? Thanks, Philippe
