Bug 908742

> mmcblk0: p1

looks as if it could read the partition table
to find out that that there is one partition on it.

please try as root
mount /dev/mmcblk0p1 /mnt
df -h /mnt

which should show something like 59G free disk space

needed to do

mount -t exfat /dev/mmcblk0p1 /mnt

witout -t exfat nothing worked

i get

/dev/mmcblk0p1      60G    8,5G   52G  15% /mnt

with the df command.

so it's seem system is not able to detect file system correctly

Please add a line with "exfat" to /etc/filesystems
and see if that helps.
I now remember that MicroSoft lobbied this new filesystem into the SDXC standard.

The alternative is to put some other filesystem (e.g. fat32) onto your card with
mkfs.vfat /dev/mmcblk0p1
but that might have side-effects for use in embedded devices.

There is apparently no problem with reading SDXC.

This is a problem of exFAT file systems. openSUSE cannot legally distribute patent encumbered exFAT file system driver. You probably installed third party package. And this third party package did not initialize itself correctly.

To be able to auto mount exfat file system, one of following needs to be done:
- load the file system module on each boot
- add the file system name to /etc/filesystems (preferred)

It is questionable, whether exfat should be a part of /etc/filesystems by default, especially if it is not supported.

in my 
/etc/filesystems i have

fat
hfs
minix
reiserfs
exfat
exfat_fuse

and my card is not detected automatically

so in console i still need to type: mount -t exfat /dev/mmcblk0p1 /mnt
anything else to detect this file system automatically

Where/how did you get the exfat support?
Could you try moving the exfat entry to the top of the /etc/filesystems file
or drop the exfat_fuse one
something is strange there...

get the exfat from

obs://build.opensuse.org/home:ZaWertun

i removed exfat_fuse from the file, changed nothin, don't know if it need to reboot...

I think this is a known bug in libblkid1.
You can read more about this in Ubuntu bug #1389021.
The original report is in:

https://github.com/karelzak/util-linux/issues/119
The fix is the following commit:
https://github.com/karelzak/util-linux/commit/98b539c25caede8534ffaf06e67a694eeb3bc6cb

I didn't test this yet, because I found this info just a few minutes ago.

Best regards

Gottfried Necker, comment 8: Yes, it looks as a valid point.

It is a side effect of blkid aborting on first I/O error fix: http://www.spinics.net/lists/util-linux-ng/msg08976.html

It surely makes sense to backport it.

It will not bring exFAT support, but it will fix its detection.

I just prepared testing packages:

Could anybody who encountered this problem test whether it will now detect exFAT properly?

Installation of libblkid1 should be sufficient.

Project:
https://build.opensuse.org/project/show/home:sbrabec:branches:OBS_Maintained:util-linux-%62%6e%63908742

Packages:
http://download.opensuse.org/repositories/home:/sbrabec:/branches:/OBS_Maintained:/util-linux-%62%6e%63908742/openSUSE_13.2_Update/

My short text indicates that it should be a correct fix.

I installed upper mentioned fuse-exfat and exfat-utils.

Then I created test image:

dd if=/dev/null of=test.img bs=1024 seek=65536
mkexfatfs test.img 

Before:
blkid test.img 
(no output)

After:
blkid test.img 
test.img: UUID="1231-F346" TYPE="exfat" PTTYPE="dos"

I did a quick test using a exfat-formatted 64GB SDXC card. Without the patched libblkid1 I can only mount the filesystem when I specify the type using the -t option to mount. With patch it works without -t. I can still mount vfat-formatted cards without specifying the type. I've used the patched libblkid1 from comment #10.

At least for me: problem solved. Thanks.

with the libblkid1 patched, i don't need to add -t to mount...
but kde don't mount automatically the file system... and in 
/etc/filesystems, i have exfat.

*** Bug 914758 has been marked as a duplicate of this bug. ***

Unfortunately, I saw this report too late and build my own package with the patch. The patch works perfectly as reported here.

I saw that there is a patchinfo present in the package from https://build.opensuse.org/project/show/home:sbrabec:branches:OBS_Maintained:util-linux-%62%6e%63908742 (thanks to Stanislav Brabec) but the current package seems to have some conflicts with its base package. Is this package going to be released as an official update?

Thanks for the hint.

OBS request 281299 was declined:

The submit is broken because of a conflict in spec-file. Could you resolve the conflict and submit again please? Thanks.
