[Bug 1728354] Re: ntfs: unsupported reparse point

[Nino Burini]

I am running into the same error message. In my case it's when I try to
access the OneDrive folder from linux:

ls -la OneDrive
lrwxrwxrwx 1 root root 25 Nov  8 17:48 OneDrive -> unsupported reparse point

I installed the systcomp and dedup plugins, but the error is still
there.

Running fsutil on Windows, I get the following:

D:\>fsutil reparsepoint query OneDrive
Valore tag di reparse: 0x9000301a
Valore tag: Microsoft

The interesing part is the value of the reparse tag, 0x9000301a. That
should identify the type of reparse point. Searching for that number,
the only mention with some meaning I find is from this file on github:
https://github.com/jschicht/MftRcrd/blob/master/MFTRCRD.au3

Case $ReparseType = '0x9000301A'
    Return 'CLOUD_ROOT_ON_DEMAND'

So it might be a new type of reparse point, specific for OneDrive.

Title:
  ntfs: unsupported reparse point

Status in ntfs-3g package in Ubuntu:
  Confirmed

Bug description:
  I recently updated my Windows-10 to the 1709 edition. Scanning the
  file system with Ubuntu, I get "unsupported reparse point" errors.
  Searching the web indicates that ntfs cannot handle certain files.

  I am running Ubutu-Mate 17.10:

  uname -r: 4.13.0-16-generic

  lsb_release -rcid:
  Distributor ID:	Ubuntu
  Description:	Ubuntu 17.10
  Release:	17.10
  Codename:	artful

  I include a file which runs ntfsinfo on a file where I get the "unsupported reparse point" message:
  sudo ntfsinfo -F /Windows/hh.exe /dev/sda1 >unsupported_reparse_point.txt

  while mounted: I issue ls -l <mount_point>/Windows/hh.exe 
  ls -l Windows/hh.exe 
  lrwxrwxrwx 2 .. .. 25 Sep 29 14:41 Windows/hh.exe -> unsupported reparse point

  I expect to see either a resolved link or a length for the file in
  question.
