ah..this should be tab shows ext3/ext4

Comment 2 Tomáš Bžatek 2012-02-06 14:45:46 UTC
So, found this related commit: http://git.gnome.org/browse/glib/commit/gio/glocalfile.c?id=25ff8ee7486c7bdf1612d3554fc1d7d91daedfa6

And tested myself: created an empty file, called mke2fs on it, and got this output:

> $ tune2fs -l test.bin 
> tune2fs 1.42 (29-Nov-2011)
> ...
> Filesystem magic number:  0xEF53
> Filesystem revision #:    1 (dynamic)
> Filesystem features:      ext_attr resize_inode dir_index filetype sparse_super
> ...

So there's no journal and plain mount command autodetects ext2. But it looks like the filesystem is indeed ext3 without journalling (ext2 mode?). Pure ext2 filesystem should have the 0xEF51 magic number. Could you please check on your side?

This is just a partition type. And udisks is not used for file:// URI scheme.

And that's probably the culprit here - we show filesystem type information based on physical filesystem data, not showing the actual mode the fs is mounted as. As long as other filesystems use different magic numbers for their versions, this is only the case for ext{2,3,4,5?}.

> $ mount
> /tmp/test.bin on /tmp/te type ext2 (rw,relatime,errors=continue,user_xattr,acl)

> $ gvfs-info -f file:///tmp/te
>   filesystem::type: ext3/ext4
Could you also please output of this command?
