[Bug]: start-on-windows-boot fills disk with logs #21

Open jamesianberry opened 2 years ago

jamesianberry commented 2 years ago

Describe the bug

Perhaps just on my system, but I had enabled Distrod on Windows startup as a new distribution with the following command: sudo /opt/distrod/bin/distrod enable --start-on-windows-boot My Windows system drive was being filled up with thousands of 8MB files in the following directory: C:\Users\username\AppData\Local\Temp\DiagOutputDir\RdClientAutoTrace The rapid creation of files stopped once I disabled Distrod on Windows startup with the following commands and then restarted Windows (afterwards, only a few files are created, at least one for each distro started): sudo /opt/distrod/bin/distrod disable sudo /opt/distrod/bin/distrod enable

Steps to reproduce

  1. In Windows Terminal, from the drop down select Distrod
  2. Enter the following command: sudo /opt/distrod/bin/distrod enable --start-on-windows-boot
  3. Enter your Distrod password 
    [Distrod] Distrod has been enabled. Now your shell will start under systemd.
[Distrod] Enabling atuomatic startup of Distrod. UAC dialog will appear because scheduling
a task requires the admin privilege. Please hit enter to proceed.
  4. Press Enter to start the UAC dialog entry
  5. Press Yes on the Task Scheduler UAC dialog
  6. Enter your Windows password
  7. Restart your Windows PC
  8. Check the following directory for log files with the type of ETL being created at a rapid rate C:\Users\username\AppData\Local\Temp\DiagOutputDir\RdClientAutoTrace

Expected behavior

Distrod starts on Windows startup without thousands of files being created in C:\Users\username\AppData\Local\Temp\DiagOutputDir\RdClientAutoTrace

additional comment

It looks like the files still get created for every distro started from Windows Terminal but this is at a much lower rate. I am seeing more than one 8MB file being created per second when Distrod starts on Windows startup

Hi, thanks for trying Distrod.

  1. I wasn't able to reproduce this problem. One thing I noticed is that your kernel is newer than mine, though Windows version is the same. My kernel version is 5.10.60.1. Are you on preview build?

  2. also, could you provide the journalctl output, please? I guess wslg or something is writing some error / warnings, because RdClientAutoTrace looks related to WSLg. You already provided a log, but it's empty. Empty log is impossible, because at least there should be kernel boot message. Please share the recent parts of sudo journalctl.

  3. lastly,

    the files still get created for every distro started from Windows Terminal

    Does this mean that your non-Distrod distro is causing the same issue?

jamesianberry commented 2 years ago

Hi Takaya, thanks for your help on Distrod.

  1. I am now installing and updating WSL from the Microsoft Store, and yes, it is the preview build: https://www.microsoft.com/store/productId/9P9TQF7MRM4R

  2. The journalctl output seems to show a lot of errors before I made the changes to stop the excessive logging: journalctl.txt

  3. It seems that only non-Distrod distributions now have a log file created each time they are started.

@jamesianberry Do you see weston crashing in dmesg of WSL? It's writing some kind of stack trace once per second for me. This with enabling auto-starting of WSL with the Windows task scheduler and enabling systemd in WSL.

@aki-k yes, this looks to be the same error my system was getting (see journalctl output above):

I guess the questions are:

aki-k commented 2 years ago

is this a WSL2 problem rather than a Distrod problem? (in which case, it should be raised elsewhere)

I don't know if this is the same problem I have but I opened an issue at https://github.com/microsoft/wslg/issues/564 but got no replies. I didn't even think of checking that directory C:\Users\username\AppData\Local\Temp\DiagOutputDir\RdClientAutoTrace on Windows side.

Karl-Larson commented 2 years ago

It looks like this might be tied to the preview version of WSL2 from the store. I had this same issue with the logs eating up almost 500GB. (Wish i checked dates on them before cleaning it up.)

I uninstalled the preview version of WSL2 from the store and no more logs were being created upon starting any WSL2 instance. While previously any WSL2 instance starting from a shut downed state via "wsl --shutdown" would create a log and fill it once killed with the same command.

I am running windows 22000.493. The preview kernel was the latest as of 2/12/2022, 5.10.93.2. Once the preview was removed I was running 5.10.60.1.
