Repro Steps

I would like to mount my homedir inside WSL from a separate virtual disk. Hence, I performed the following steps:

1. I used Hyper-V manager to create a new vhdx file at C:\Users\<username>\home.vdhx.

2. In an Administrator PowerShell which started with the working directory in my user profile directory (i.e. C:\Users\<username>), I mounted the new vhdx file as a drive:

Mount-VHD -Path .\home.vhdx

After doing that, the vhdx file will appear as a physical driver:

PS C:\Users\lagga> wmic diskdrive list brief
Caption                 DeviceID            Model                   Partitions  Size
XPG GAMMIX S70 BLADE    \\.\PHYSICALDRIVE0  XPG GAMMIX S70 BLADE    3           2048407280640
Microsoft Virtual Disk  \\.\PHYSICALDRIVE1  Microsoft Virtual Disk  0           1099506078720

3. Mount the new physical drive in WSL:

wsl --mount \\.\PHYSICALDRIVE1 --bare

4. Start my WSL distribution.

5. In Linux, a new device will appear:

# lsblk
NAME MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda    8:0    0   256G  0 disk
sdb    8:16   0 339.8M  1 disk
sdc    8:32   0     1T  0 disk
sdd    8:48   0   256G  0 disk /

The vhdx file is mapped to sdc.

6. Created a btrfs file system in /dev/sdc:

mkfs.btrfs -L home /dev/sdc

I verified that I can properly mount /dev/sdc. I also created a btrfs subvolume for my homedir called laggarcia.

7. Used blkid to find /dev/sdc UUID.

8. Added a line to mount the UUID on my homedir in Linux in /etc/fstab:

# cat /etc/fstab
LABEL=cloudimg-rootfs   /        ext4   defaults        0 0

UUID=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX       /home/laggarcia btrfs   subvol=laggarcia        0 0

9. Verified that mount -a properly mount my homedir.

10. Shutdown WSL with wsl --shutdown.

11. Mounted the vhdx physical drive in WSL again (repeat step 3).

12. Start WSL instance.

13. When the prompt appears, I am not seeing the files inside my vhdx file. I have no errors in dmesg. As a matter of fact, it states that it correctly identified /dev/sdc.

However, if I run mount -a just after starting the WSL instance, my homedir will become the one inside the vhdx file.

Expected Behavior

I would expect that the homedir from the vhdx file should be correctly automount during WSL instance boot.

Actual Behavior

Homedir is not correctly automounted.

I have a much more simple test case now that hits the same issue. Just create a directory inside your user profile directory in Windows and put the following on your /etc/fstab:

# cat /etc/fstab
LABEL=cloudimg-rootfs   /        ext4   defaults        0 0

C:\     /mnt/c  drvfs   noatime,uid=1000,gid=1000,metadata      0 0
/mnt/c/Users/lagga/linux-home-dir       /home/laggarcia none    bind    0 0

When WSL instance starts, your homedir will not be bind mounted. You will have to run mount -a to mount it properly.

use the windows store version of WSL

Having the ability to keep your home directory as a separate VHD would be really useful for the often many times I need to trash and recreate my development environment distro. It also has the added benefit of being able to be used by multiple distros.

The main issue is that there is no support in WSL 2 for automounting a VHD on distro startup. We have wsl --mount --vhd now but that does not get around the issues described above.

Any update with this problem? Any other idea or workaround? Will someday this be fixed?

This is also related to #11805 and others. But I came back to this issue because I'm trying to have the home folder in a different location than the "default" distro disk.

• Also I tried to follow the approach that Docker team does with Docker Desktop (different distro).

1. Mount the /home/ from the source distro into the target distro
   This is defined in a shell script that runs at boot in our target distro.

2. However, the user home folder is never ready with the contents at the first boot, only if we open a new session. It's seems that this kind of sync or order processing makes this unfeasable, sadly.
