[Bug 296750] Re: "special device /dev/dm-0 does not exist" when mounting an encrypted drive
This bug still exists in lucid. When it occurs, you can manually fix it once using hal-set-property, but on the next occasion it reoccurs of course. Could one of those familiar with the mount-process in hal please shed some light on the issue? Especially it would help if you could give any hint on where to start debugging this problem.

[Bug 296750] Re: "special device /dev/dm-0 does not exist" when mounting an encrypted drive
I have this problem as well, and what's more confusing is it just started. The volume used to work by clicking the item in nautilus, now it always fails by asking for the password over and over. However, the mapper entry is being created it's jsut being mounted. I can go into a command line and tell it to mount the mapper and it works fine at least until i have to unmount it, as that also has to be doen manually.

[Bug 296750] Re: "special device /dev/dm-0 does not exist" when mounting an encrypted drive
I further investigated this issue and found out the following: Whenever it works, the hal entry for the unlocked device, which should get mounted, contains the following line: block.device = '/dev/mapper/luks_crypto_fb656bfe-460b-4437-97d6-93bb6e9e66c4' (string) Whenever it doesn't work, this line reads: block.device = '/dev/dm-4' (string) So this is the reason, the device cannot be mounted by gnome-mount. How are these entries created? During this conversation (http://lists.freedesktop.org/archives/hal/2008-April/011440.html) a race condition is described, which could cause hal to pickup on the dm-4 device and not notice the change after it has been unlocked.

I wonder why this has an importance=low as it breaks encrypted disks, but well.

[Bug 296750] Re: "special device /dev/dm-0 does not exist" when mounting an encrypted drive
When mounting manually, the standard way is to "map" the encrypted drive or partition using "cryptsetup luksOpen", which automatically creates a mapper device in /dev/mapper/. gnome-mount (or is HAL responsible for this?) seems to be doing it the same way, choosing an alias "luks_crypto_". It seems that instead of mounting this device after it is created, gnome-mount tries to mount /dev/dm-0 for some reason. And for some reason, it only does this sometimes. -- "special device /dev/dm-0 does not exist" when mounting an encrypted drive https://bugs.launchpad.net/bugs/296750 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 296750] Re: "special device /dev/dm-0 does not exist" when mounting an encrypted drive
I'm not sure about that. /dev/dm* are temporary device mappers if I am not mistaken. They used to be associated with LVM which would make perfectly sense, as I have a logical volumes in the encrypted drive. However I read somewhere that some volatile devices like flash cards also use /dev/dm* devices.

I can confirm this problem, I have two machines, each connected to four encrypted drives (cryptsetup,luks, different usb 2.0, different drives from different vendors). It is a common problem so I very often cannot mount all the drives via the menu (Places->Removable Media->...), but one of them fails so I can only use 3 of 4.

I can confirm this on a freshly installed intrepid ibex. To reproduce: Plug in a fully encrypted disk, the password dialogue pops up.

Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken. If mounted manually the message reads: ~$ gnome-mount -vbd /dev/mapper/luks_crypto_[...] gnome-mount 0.8 ** Message: Given device '/dev/mapper/luks_crypto_[...]' is not a volume or a drive.

[Bug 296750] Re: "special device /dev/dm-0 does not exist" when mounting an encrypted drive
Thanks for finally answering, but why do you say so? I don't see the same error message anywhere in that thread, and the other bug is quite old. My problem started in Intrepid. Here are some additional details I can think of. The most interesting thing is probably that this does not happen consistently. Any ideas what might cause the drive to mount correctly about half the times and not mount at other times? When the error pops-up, the drive is LUKS-opened correctly, it is possible to manually mount it like "sudo mount /dev/mapper/luks_crypto_ac639614-9758-4555-9c97-90d4796d9c8b /mnt". However, "gnome-mount -vbd /dev/mapper/luks_crypto_ac639614-9758-4555-9c97-90d4796d9c8b" gives the following output: gnome-mount 0.8 ** Message: Given device '/dev/mapper/luks_crypto_ac639614-9758-4555-9c97-90d4796d9c8b' is not a volume or a drive.
