[SOLVED] Udev not linking USB drive, unable to figure out why.

grmrgecko · 07-31-2013, 07:45 PM

I have been trying to get my PowerPC install of Debian 7 to link /dev/sdc, or wherever the usb drive is, to /dev/usbdrive* with udev and I am unable to get this to work.

Here is my device walk through, my rule, and my syslog.

debian-powermac:/etc/udev/rules.d root 14:19:59$ udevadm info --attribute-walk --name /dev/sdc
custom logging function 0x101df008 registered

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

(I truncated some of the above as it's not necessary/I hit the limit of characters in a post.)

Can someone help me figure this out? My goal is to auto mount my USB HDD at boot. I tried using autofs with UUID, but I don't see any results or I don't know how it is suppose to work...

debian-powermac:/etc root 14:38:28$ cat auto.master | grep "/media/"
/media/Data /etc/auto.removable --timeout=2,sync,nodev,nosuid
debian-powermac:/etc root 14:37:30$ cat auto.removable
usb -fstype=ext4 UUID=dd4e3d6a-1ffc-427c-9ff4-ad8b4ad62914

I would expect the drive to be mounted at /media/Data or at /media/Data/Data, but I don't see it's files at those locations.

debian-powermac:/etc root 14:40:41$ blkid | grep "/dev/sdc"
/dev/sdc: LABEL="Data" UUID="dd4e3d6a-1ffc-427c-9ff4-ad8b4ad62914" TYPE="ext4"

Can someone help me understand this or get this to work?

Thanks

I would try mounting the drive by placing the following lines near the bottom of /etc/fstab

# USB HDD
UUID=dd4e3d6a-1ffc-427c-9ff4-ad8b4ad62914 /media/Data ext4 defaults 0 2

Works like a charm.

I noticed while I was going through setting this up, the links for usbdrive were set, maybe a reboot was all that was needed? I thought restarting udev/reloading rules will make it work as rebooting this old machine takes 10 minutes+ and I didn't want to go through the reboot process remotely.

I decided to go with your fstab solution rather than autofs as I will always have the USB drive connected, and when I unplug it, I'll know to mount it.

Thanks for your reply!
