Access Windows OneDrive directory from Linux

[KarlNapp2023]

Dear all,

I try to use the same directory for syncing to OneDrive from both Windows 10 and Linux Mint 21.2 (dual boot system). The OneDrive directory is on a NTFS SSD.

Unfortunately I can't access the directory from Linux if the OneDrive directory is connected to the Microsoft account (i.e. syncing is active, existing reparse point). When I remove this connection, I can access the OneDrive directory from Linux (reparse point gone).

Error message in Linux when trying to access the OneDrive directory: "unsupported reparse tag 0x9000701"

From my understanding this behaviour is caused by files on demand turned on. Unfortunately this feature is turned off and all files are saved on my NTFS SDD (almost 100 GB)

What didn't work:

1. Removing the reparse point via fsutil reparsepoint delete D:\OneDrive => access denied

2. Turning off files on demand. Unfortunately the screenshots in onedrive/docs/advanced-usage.md look different, so I pressed "Download all files" and checked "Always keep on this device"

3. Turning off files on demand in policies (gepedit.msc)

Any idea how to use the same OneDrive directory both in Windows and Linux?

The only way for you to share the data between Windows and Linux is to disable Files On-Demand in Windows.

If this is becoming problematic to unset Files On-Demand in Windows - then this is a Windows problem that I cannot help you with.

Suggest you reach out to Microsoft and/or Windows support forums for assistance in disabling Files On-Demand in Windows.

Thanks for the information. I finally managed to gain access to the folder by installing ntfs-3g-onedrive (just in case someone else has the same problem)

I'm going to go with this approach, which seems to me to be the most appropriate.
I'm not used to compiling and, when I run it following the instructions given, it generates two files ntfs-plugin-9000001a.so and ntfs-plugin-9000001a.la : is the second necessary for the first to work properly ?
according to the internet, the text file ntfs-plugin-9000001a.la is relative to libtool and is therefore only necessary/useful for compiling : is that correct ?

@patatetom
I have no idea regarding that tool. Best raise a question on that GitHub repo for your answers - sorry.

Hi, I managed to install the plugin and got read, but not WRITE access to my windows Onedrive folder. Any solutions ? sudo chmod doesn't work here.

[patatetom]

hi,
I can't give you any information on this point, as I've installed this plugin in order to have RO access to any files that may be present.
have you checked that the mount (by hand) was done in RW mode and that the UID option is set to the right user (you) ?
regards, lacsaP.

It is best you ask your question regarding Read|Write access on https://github.com/gbrielgustavo/ntfs-3g-onedrive/

As @patatetom mentions - it could be to do with how you are mounting your Windows drive under Linux
