Hey,

I wanted to compress my wsl distro, but it shows me that the estimated size is going to be way larger than the current size:

Does anyone has an idea what could be the reason?

Thanks for your help

Installation problem with Powershell 7.3.2

I have just tried to install the utility as a powershell module using Powershell 7.3.2. I correctly set the execution policy as specified in the installation guide. Nevertheless I get the following prompt

Apparently powershell in my configuration does not recognize wget as a powershell cmdlet and this prevent the module to be installed as it can be seen from the subsequent lines. I am not an expert of powershell, so I have been asking to myself: "Is this a problem with my configuration?". Have you ever faced this issue? Do you know a possible workaround?

Needs 0MB of free space

Used scoop to install instead, running wslcompact gives:

Please, change the TEMP folder to a drive with at least 0 MB of free space.
You cand do it by typing $env:TEMP="Z:/your/new/temp/folder" before using wslcompact.

I hope you don't mind the bug reports. I might do this manually as disk tools with errors are a bit scary. Nothing personal.

How to clear the swap.vhdx at first?

Hey,

I am using WSL2 Ubuntu and I know that there is an issue with wsl in general capturing memory and not releasing it back. Thats why I wanted to use wslcompact but before that it says that I should clear my temp folder at first. The swap.vhdx file takes almost 50gb and I can not clear it. Does someone know how I can do this?

Thanks for your help

wslcompact doesn't release space, despite available space

While WSL has a lot of available free space, wslcompact doesn't identify it for removal (see below). Changing the temp file as suggested didn't help either. For what's it worth I tried to also compact it with diskpart, but while it said it compacted the disk nothing happened. So perhaps the issue is related to diskpart rather than wslcompact.

Failed to attach disk 'C:\Users\bijay\AppData\Local\Packages\CanonicalGroupLimited.Ubuntu20.04LTS_79rhkp1fndgsc\LocalState\ext4.vhdx' to WSL2: The APPX file can not be accessed because it is not encrypted as expected. Error code: Wsl/Service/CreateInstance/MountVhd/0x80070199

Tried the PowerShell method everything worked fine, The virtual disk shrunk from 48GB to 28GB, but when tried to launch wsl it didn't work and the following error showed up

Failed to attach disk 'C:\Users\bijay\AppData\Local\Packages\CanonicalGroupLimited.Ubuntu20.04LTS_79rhkp1fndgsc\LocalState\ext4.vhdx' to WSL2: The APPX file can not be accessed because it is not encrypted as expected.

Is there a way to fix this or all my data is gone??

compacting was successful but wsl became corrupted, cant start it anymore
tried to mount manually but every attempt failed. be careful before running this thing.

Compacting NixOS failed with unspecified error

To get the script working with NixOS I needed to change the path to df to /run/current-system/sw/bin/df.

Then after multiple errors the script failed with a very generic error message and immediately deleted the temporary vhdx so I couldn't inspect that.

Weird error message about free space

When attempting to compress an image without enough free space, I get this error message:

The estimated process time using an SSD is about 5 minutes.

WARNING: there isn't enough free space in temp drive C to process Ubuntu-22.04.
There are only 5141 MB available.

Please, change the TEMP folder to a drive with at least 0 MB of free space.

Notice the 0 MB of free space.

Memory usage 8GB+

I think this is related to the approach to pipe the export to import:

wslcompact/WslCompact/WslCompact.psm1

Lines 95 to 97 in b9eee55

 wsl --shutdown 

 cmd /c "wsl --export ""$wsl_distro"" - | wsl --import wslcompact ""$tmp_folder"" -" 

 wsl --shutdown

I've seen this use over 8GB (roughly size of image) in memory, which if there was not enough free would fail even if there is adequate disk space. Running these two commands sequentially without the pipe avoids the high memory usage.

It might be good to offer an option to opt-in for the alternative without using a pipe?

I could be mistaken, I've not tried to use wslcompact on a much larger VM disk to see if the memory required is expected to scale. Doesn't seem like it's affected by the original size, but the compacted export size might be the memory requirement which is being piped?

I recently also ran wslcompact and it was managing at 98% memory usage (32GB system), although I think this was not failing as some other processes that are memory gluttons like Edge will release memory when the system is under pressure.

I did realize I was not going to have enough disk space and pressed Ctrl +C during the operation, VmmemWSL process was using roughly 10GB of memory (nothing else open due to wsl --shutdown). However I wasn't able to release it via explicit wsl --shutdown command (hangs), and the process was not permitted to terminate via the Task Manager.

I vaguely recall something similar with the memory pipe failure I experienced last month. I didn't abort that operation, but the failure didn't release the memory either IIRC.

EDIT: I roughly documented it in the middle of this comment, closing the powershell terminal app didn't make a difference this time, although the memory usage of VmmemWSL process has been slowly reducing over the past hour from 10GB to 2GB presently (now 1.4GB).

WSL distro corrupted

I've successfully shrinked my WSL image but when I enter Ubuntu it seems corrupted: all files in /etc/ are binaries and therefore the OS can't use them. How can I fix this or do I have to reinstall all?
