Unable to mount exfat after updating: libutils-linux 2.25-3?

and-bnk · 2014-08-06 14:37:19

Hi everyone!

I have just updated my system and libutils-linux has been upgraded to version 2.25-3 from version 2.24.2-1.
The problem is:
after the update, I could not mount my exfat device: some errors occur.

In details:
1- The device is a Truecrypt encrypted usb pen and the partition is formatted with exfat.
2- The problem is not Truecrypt itself since I have no problems on decrypting my usb pen. The problem occurs when trying to mount /dev/mapper/truecryptx.
3- Since device-mapper has been upgraded (to version 2.02.108-1 from 2.02.106-2) as well, at the beginning, I thought that the problem was due to the new release of device-mapper. But this is not the case since the problem also occurs after downgrading device-mapper to the previous version. Moreover, on second thought, I realized that everything is with device-mapper for my system is luks encrypted.
4- The error message is:

 mount: wrong fs type bad option bad superblock
 missing codepage or helper program or other error

5- I am pretty sure the problem is exfat+libutils. Indeed, I have no such problems after downgrading to version 2.24.2-1.
Plus, I do not experience any of these troubles when mounting the same device on the other laptop of mine. The latter is again an Arch Linux system and it is configured the same way the former is (e.g., same kernel), except the fact that I did not updated it (this means that the version of libutils-linux is still 2.24.2-1).
6- To be honest, I could not try to mount any other filesystem (apart ext4 and btrfs, which are installed on both my laptops) simply because I only have (external) devices formatted with exfat.

So,
is it a bug, or am I missing something?

Thank you in advance for any comment or advice.

Best,
and-bnk

1. Provide the complete mount command you used.
2. Try mounting a non-encrypted exfat partition and see if it is exfat or the encryption. This will rule out half of the possible culprits.

I simply used

$sudo truecrypt /path/to/device /mountpoint

to decrypt it and mount it,
and

$sudo truecrypt --filesystem=none --slot=N /path/to/device

to decrypt it only.

I confirm that the encryption is not the problem (I mounted it on other systems [another linux, windows, whatever] and everything went smooth).
I guess I figured out the problem: it seems like the problem is the command "mount" (not sure if only combined with exfat yet).
In fact, I decrypted the device via Truecrypt using the second of the above commands (which then /dev/mapper/truecryptN) and I tried to mount it. Now:
- using

$sudo mount /dev/mapper/truecryptN /mountpoint

the above error message appears, whereas
- using

$udiskctl mount --block-device /dev/mapper/truecryptX

I can mount it successfully.
As a matter of fact, the first command above fails [probably just] because Truecrypt uses "mount" to mount the decrypted devices.

Any ideas?

Thank you in advance!

Same issue here with a simple exFAT formated SDcard (performed in a in a GoPro Hero 3+). Downgrading to libutil-linux-2.24.2-1 fixes the problem. I will submit a bug in the tracker.

Strange, my bug has been marked as a duplicate but doesn't seem the same to me.

Here are the journalctl and udisks outputs with the different version of libutils-linux:

Of course it's the same. exfat + util-linux-2.25 = mount failure. Both bugs convey the same thing, you just picked the other part of the equation to file the bug against (util-linux instead of exfat). If you read the bug report I dup'd yours to, you'll see that fuse-exfat upstream has already fixed the bug in trunk. There's nothing to be fixed in util-linux -- mount helpers simply need to abide by the mount helper API, which mount.exfat did not.

Thanks @falconindy for the detailed explanation.I will use the downgrade workaround for now.
