OneDrive: unsupported reparse tag 0x9000701a #44

Closed Merlin04 closed 2 years ago

Merlin04 commented 2 years ago

I have a drive with an NTFS partition that OneDrive on Windows 10 is configured to sync to (I've tagged the whole onedrive folder with "keep offline" so everything is downloaded locally). However, when I use the latest version of ntfs-3g (2022.5.17) the folder shows up as a broken symlink, with the target listed as

unsupported reparse tag 0x9000701a

I also tried mounting the drive with the old version of ntfs-3g included with the distro (2017.3.23AR.3-3ubuntu1.2) and while that allowed me to see the contents of the folder, all files were broken links with

unsupported reparse point

I tried running ntfsinfo and got this debug information:

For accessing local OneDrive files, you need a specific plugin and an ntfs-3g version at least 2017.3.23AR.4. See : https://github.com/tuxera/ntfs-3g/wiki/Junctions-Points,-Symbolic-Links-and-Reparse-Points#user-content-other-types-of-reparse-points

There is an experimental plugin at : [ edit : obsolete link removed ]

from which the file ntfs-plugin-9000001a.so matching your configuration is to be copied into the directory shown by ntfs-3g -help Note however that I have not been able to reinstall OneDrive on my Windows 10 computers, and there may have been changes. Please report about your findings.

sfrmattos commented 2 years ago

@jpandre the link for the plugin is "broken". was it upload somewhere else?

vanguish commented 2 years ago

I found the plugins on wayback machine (let's hope the broken links are fixed soon): dedup.zip onedrive.zip

The experimental implementations of some reparse-oriented features are considered not fit for stable use at this point, but we are working on stabilizing them, eventually adding to a stable release. Experimental features tend to be very dangerous in general and supporting them for us before they are stable is hard. We are working to get them stabilized and included in future releases. If you intend to get them sooner, please contact Tuxera Inc. at sales@tuxera.com for commercial support.

vanguish commented 2 years ago

If you are attempting to stabilize these features, then why are you discouraging users from testing them by removing download links? How can something be stabilized without extensive field testing?

hv0905 commented 1 year ago

If you're still interested in accessing your Onedrive directory via ntfs-3g, I recommend checking out this repository: ntfs3g-onedrive-plugin.

It has been tested and confirmed to be working with the latest version of ntfs-3g.

For detailed instructions on how to build and install the plugin, you can visit my blog.(In Chinese only)
