[fuse-devel] Help detecting ntfs fuse filesystem type

[nbenitezl . <nbe...@gm...>]

Hi, I have an external usb hard disk with two partitions, one is vfat
and the other is ntfs. Nautilus file manager in gnome desktop of my
fedora 19 is not showing the filesystem type of the ntfs partition,
see empty value on bottom right of this screenshot:

So after some investigation, it seems it does not show it because the
filesystem magic number returned by statfs field is the one of FUSE
filesystem, that is right, because ntfs3g uses FUSE..


..so then I'm looking for a way to detect the real filesystem type
under FUSE, to show in the nautilus label, and found this commit by
Miklos Szeredi which should have resolved the issue:

https://lkml.org/lkml/2007/2/12/154

My understanding of that commit is that /proc/mtab and /proc/mounts
should now display 'fuseblk.ntfs' instead of just 'fuseblk' but in my
system it's only the later which gets printed:

$ cat /proc/mounts | grep "nelson/dev"
/dev/sdb2 /run/media/nelson/dev fuseblk
rw,nosuid,nodev,relatime,user_id=0,group_id=0,allow_other,blksize=4096
0 0

$ cat /etc/mtab | grep "nelson/dev"
/dev/sdb2 /run/media/nelson/dev fuseblk
rw,nosuid,nodev,relatime,user_id=0,group_id=0,allow_other,blksize=4096
0 0


Nonetheless, in /etc/fstab it appears as 'ntfs' :
$ cat /etc/fstab | grep "nelson/dev"
UUID=786F49A712A2C7E6 /run/media/nelson/dev ntfs
nosuid,nodev,nofail,noauto,x-gvfs-show,exec 0 0


but I don't feel good reading it from /etc/fstab as in fedora it is a
generated file from anaconda installer, and I feel /etc/mtab of
/proc/mounts should be more reliable source to get this info..

so, do you have any idea why my system is not displaying
'fuseblk.ntfs' in /etc/mtab and proc/mounts ? is there a more reliable
way to detect ntfs type under fuse ?


Thanks
