Udev auto mounting not recognising my labels

phunni · 2010-09-29 11:12:21

I have added the auto mounting rules to my udev config exactly as specified in the wiki:

http://wiki.archlinux.org/index.php/Ude … if_present

This works to the extend that I can see the devices being mounted under media, but, for most of my deviecs, I have labels defined in /etc/fstab/:

/dev/disk/by-uuid/74C7-B9D3 /media/android vfat noauto,users 0 0
/dev/disk/by-uuid/20A0-683F /media/cowon vfat noauto,users 0 0
/dev/disk/by-uuid/A036-C3DF /media/cowonsd vfat noauto,users 0 0
/dev/disk/by-uuid/00C6-17D0 /media/ipod vfat noauto,users 0 0
/dev/disk/by-uuid/68DB-1857 /media/cardreader vfat noauto,users 0 0
/dev/disk/by-uuid/72AD-2013 /media/acekard vfat noauto,users 0 0

For some reason, however, they are being mounted as /media/usbhd-sd*

What am I missing here?

You're using disk-by-uuid not disk-by-label so this won't work.

OK - is there not a way to do this via UUID and fstab? I used to use the pmount version, but wanted to try a more multi user approach.

Anyway - I did try and set a label with the following result:

# e2label /dev/sdg1 cowonsd
e2label: Bad magic number in super-block while trying to open /dev/sdg1
Couldn't find valid filesystem superblock.

Still a little lost here...

You create a label and call your drives by the label.

http://wiki.archlinux.org/index.php/Per … ice_naming
Every filesystem uses it's own tools, vfat needs mlabel from the mtools package.

phunni · 2010-09-29 16:36:09

This isn't making much sense to me I'm afraid. I tried creating a label called 'cowon' and then there was /dev/disk/by-label/COWON - s that the way it's supposed to be?

Yes, that's the way it's supposed to be. Mountpoints are something different.

Instead of

/dev/disk/by-uuid/20A0-683F /media/cowon vfat noauto,users 0 0

try setting up

/dev/disk/by-label/COWON /media/cowon vfat noauto,users 0 0

phunni · 2010-09-29 17:23:27

OK - I think I'm making progress. It now creates a new directory called COWONSD under /media where one of my devices is mounted. In fstab, this device is mapped to /media/cowonsd using /dev/disk/by-label/COWONSD

Is there anyway I can get these devices mounted to the correct places as specified by fstab?

Interestingly, I currently have 2 devices plugged in - but only one is showing at a time... Perhaps that's another issue...

karol · 2010-09-29 19:05:16

What are the correct places? If device with label 'xyz' mounts under /media/xyz according to the udev rules you've set up, seems everything is in place.

phunni · 2010-09-29 21:50:07

If I have mapped a drive with the label COWON to /media/cowon, then that's where I'd like it mounted...

That's what I meant.
<the light dawns> Ah, you mean you want lowercase?

Edit: I think mlabel uses ALLCAPS.

Thanks for all the help so far :-)

OK, so it seems like fat partitions, such as my USB drives, can't be lowercase. I guess I can live with that.

So, the cowon device that I've been referencing so far actually has 2 drives - the internal memory and the SD card. When it's plugged in, both need to be automounted.

Having plugged in the device I can see both COWON and COWONSD under /dev/disk/by-label/ but only COWONSD is mounted under /media - there is no trace of COWON being auto mounted anywhere.

How can I figure out what's going on there?

tomk · 2010-09-30 08:36:16

dmesg will tell you what the kernel sees when the device is connected - start there.

phunni · 2010-09-30 12:49:39

dmesg says:

Still only COWONSD that's mounted. That's really confused me. dmesg seems to only refer to COWON, but it's only COWONSD that gets mounted...

karol · 2010-09-30 12:50:17

You need to mount the cards (e.g. /dev/sdg1 and /dev/sdg2) then, not the device (/dev/sdg).

Is that not what the script is doing?

karol · 2010-09-30 13:01:35

Can you mount COWON by hand?

Edit: When I plug in a similar device, both cards get listed

sd 2:0:0:0: [sdb] Assuming drive cache: write through
sd 2:0:0:0: [sdb] Attached SCSI removable disk
sd 2:0:0:2: [sdd] Assuming drive cache: write through
sd 2:0:0:2: [sdd] Attached SCSI removable disk

and I can mount both.

I can mount both by hand - even when COWONSD has already been automounted

karol · 2010-09-30 13:10:58

Which one is COWONSD /dev/sdf1? /dev/sde? I'm confused too, as I see no COWONSD label in dmesg.
What happens if you insert the device w/o the card?

phunni · 2010-09-30 13:17:30

It's the lack of COWONSD that's confused me too.

This is what I get in dmesg without the SD card:

usb 1-6: new high speed USB device using ehci_hcd and address 9
scsi9 : usb-storage 1-6:1.0

 sde:

tomk · 2010-09-30 16:22:50

sde is the internal memory, sdf is the sd card, and sdf1 is the partition on the sd card. This is not uncommon e.g. my nokia has a similar setup.

So you need to mount sde and sdf1.

phunni · 2010-09-30 16:26:20

Thanks for that - makes sense.

So why are they not both being auto mounted?
