Re: Problem: The unlocked device does not have a recognizable file system on it

[tom handler <tomhandler25 gmail com>]

Hi, thanks for the prompt reply,

so I tried your suggestion with udisksctl:

$ udisksctl mount -b /dev/sdc1 (It's another external drive with sdc1 as luks)

Object /org/freedesktop/UDisks2/block_devices/sdc1 is not a mountable filesystem.
---

So I tried unlocking it with unlock:

~$ udisksctl unlock -b /dev/sdc1
Passphrase:
Unlocked /dev/sdc1 as /dev/dm-1
----

Unlocking LUKS works, but mounting dm-1 still fails:

$ udisksctl mount -b /dev/dm-1
Object /org/freedesktop/UDisks2/block_devices/dm_2d1 is not a mountable filesystem.

sudo mount /dev/dm-1 /mnt/test <-- works as expected

So it seems udisksctl mount doesn’t work either.

I did a pastebin with the output of gvfs-mount -li: http://pastebin.com/rajgtBCL

So, where do I go from here?

thanks for your help!

Is it possible to mount it with udisks?  It may be a problem with
udisks.

E.g. udisksctl mount -b /dev/sdc2

Otherwise the output of gvfs-mount -li could be helpful.
