How do you mount a USB Drive?

[7ewis]

I have been trying to mount a usb drive for the past half an hour... I really don't know what I'm doing wrong!

My drive is formatted to FAT32, this is what I have been trying (sorry it's long!):

Code: Select all

pi@raspberrypi / $ sudo mount /dev/sda /mnt/usb
mount: you must specify the filesystem type
pi@raspberrypi / $ df -h
Filesystem      Size  Used Avail Use% Mounted on
rootfs           15G  1.5G   13G  11% /
/dev/root        15G  1.5G   13G  11% /
devtmpfs        212M     0  212M   0% /dev

/dev/mmcblk0p1   56M   19M   38M  34% /boot
pi@raspberrypi / $ sudo mount /dev/sda /mnt/usb
mount: you must specify the filesystem type
pi@raspberrypi / $ sudo mount -t vfat -o uid=pi,gid=pi /dev/sda /mnt/usb
mount: wrong fs type, bad option, bad superblock on /dev/sda,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

Hi 7ewis
You've missed the partition number from your mount command.

sudo mount -t vfat /dev/sda1 /mnt/usb

Also make sure the usb folder in mnt exists. If not then

mkdir -p /mnt/usb

Stu

[joan]

Insert your dongle and do

ls /dev/sd*

You should see the sd card plus any partitions on the sd card.

e.g. /dev/sda, /dev/sda1

You need to mount the partition which will be of the form /dev/sda1, /dev/sda2 etc.

[7ewis]

Thanks Stu, didn't know I had to choose a the number, in the guide I was following it said it would just be 'sda' if that's what it said in dmesg, which it did.

Thank joan, found out from that that it was actually sda2!

So I put that with Stu's code and it mounted!


Now, is it possible to make it automatically do that every time I plug it in?

[stubright]

If you

sudo nano /etc/fstab

then add the line to the end

/dev/sda2 /mnt/usb vfat defaults 0 2

it should mount at boot, assuming the sda2 does not change, which it can if other drives exist at boot up.

A better option is to use uuid instead of /dev/
the uuid can be found using the following

ls -l /dev/disk/by-uuid/

or gparted has the same info

then your fstab line would start
UUID=long_hex_number_from_previous_command /mnt/usb vfat defaults 0 2

Using that method means it doesn't matter whether your drive comes up as sda1 or sdb2 or whatever if another drive is in when the Pi is booted.

I've always used uuid on all of my computers.

1st off I formatted my USB key ext4 so my FS might be different


mkdir /media/usb
sudo nano /etc/fstab
add this line
/dev/sda1 /media/usb ext4 rw 0 3
save and exit, then on your next reboot it should automount you can test before you reboot by typing
mount /media/usb
if it mounts then you're good to go.
also MY usb key is /dev/sda1 yours might be different
yours might look like
/dev/sda1 /media vfat rw 0 3

Stu

Just as you said this, I realised it changed to sdb2!

So:

pi@raspberrypi /etc $ ls -l /dev/disk/by-uuid/
total 0
lrwxrwxrwx 1 root root 10 Mar 22 23:20 1C2E-BAB5 -> ../../sdb2
lrwxrwxrwx 1 root root 15 Mar 22 22:46 62ba9ec9-47d9-4421-aaee-71dd6c0f3707 -> ../../mmcblk0p2
lrwxrwxrwx 1 root root 15 Jan 1 1970 C522-EA52 -> ../../mmcblk0p1
pi@raspberrypi /etc $


The UUID is '1C2E-BAB5' now? (Edit: It's working now; thanks!)

One more thing.. How can I change the permissions so that I can allow transmission-daemon download torrents directly to the usb? I don't want to keep writing to my SD card, I don't want it to wear out quickly and would prefer my downloads on a flash drive anyway.

[stubright]

Unfortunately I haven't used transmission on the Pi, however, to change ownership of a folder you

sudo chown -R your_user_name /mnt/usb

That, in theory, would give your user name the same access to the mount as root, instead of root only access.

I hope that works.

Stu

[7ewis]

I tried it using the username 'pi' and it didn't work.

But, I think transmission gets its own username or something? So would I have to put that in there?

If you ever download torrents, it's quite useful to leave your Pi on overnight instead of your PC, so you should check it out!

[stubright]

I do use transmission but only on my PC when I'm using it. Transmission is a thousand time better than any Windows based torrent crap I've use in the past.
I've just tried transmission-daemon on my Pi and it worked using an external (fstab mounted) usb drive and a web interface.

First
sudo service transmission-daemon stop

Then I edited
sudo nano /etc/transmission-daemon/settings.json
and changed
"download-dir": "/path/to/folder",
I also changed
"incomplete-dir": "/path/to/another/folder",
and
"rpc-username": "your_user_name"
and
"rpc-password": "any_password_you_want",
and
"rpc-whitelist": "ip_address_for_the_computer_you_access_it_from",
I am assuming you could add multiple white list entries
then
sudo service transmission-daemon start

login from a web browser using
/Pi_IP_Address:9091/

The folders I made for downloads and incomplete downloads were made using the Pi user and not root.

I hope that works, I'll apologise for any errors as I've only used the daemon for half an hour.
Stu

[7ewis]

Yeah that's what I had been trying, it starts to download a file, and only when the download folder is on the usb drive, towards the end of the download it will give me an error saying 'Permission Denied'.

Not sure why it happens to me and not you though, if you haven't changed anything else?

[stubright]

Do you have any spaces or unusual characters in the folder names. I can get pemission denied if there are spaces.
The path for my downloads is
/home/stu/storage/Data
but if I use
/home/stu/storage/Torrent Data
it falls over.

You might try " " around files or directories with spaces.
cd one two
does not work

cd "one two"
works

[stubright]

cd "one two"

Yes, that works on the command line but the config file for the torrent daemon already uses " " around the path. I haven't tried any other options because not using spaces in the folder names works.
Stu

[7ewis]

My download folder is just

mnt/usb/Downloads

Nothing special about it, apart from the capital in Downloads which don't think would make a difference?

Edit: Okay, forgetting transmission for a minute, I went into my usb and tried wget'ing a file, and it gave me permission denied as well, then I tried it with sudo and it worked. Surely there must be some basic permission changes that I need to do some how? I have tried all the chown comands I have found, and tried chmod 777 etc. Does it matter that it's formatted to fat32? I don't want to reformat though because I use it for other things that can only read fat32.

[stubright]

fat32 doesn't support permissions, so that is probably the problem.

In your fstab file, edit the line for your usb drive, where it says

defaults

and change it to

defaults,umask=000

that should make you the owner of the usb drive.

Stu

[7ewis]

It works now!

Thank you so much! Now I just need to setup OpenVPN and I'm good to go!

I have Samba and miniDLNA so I can stream everything from my Pi around my house!

[MartyMacGyver]

I have been trying to mount a usb drive for the past half an hour... I really don't know what I'm doing wrong!

For general usage, I got stuck on the permissions thing myself. It's pretty easy to mount a typical USB drive (e.g., FAT formatted - I haven't tested NTFS yet). Note that I'm using the "Occidentalis v0.2" version of the OS, though I expect it's pretty much the same on the standard one as well.

I've got a USB drive I wanted to work with as user "pi". I booted up and later plugged the drive in. Running "sudo fdisk -l" showed that it's being detected automagically as /dev/sda1.

At that point you create an empty mount directory (if it's not already there), e.g.:
sudo mkdir /mnt/USB

Then you mount the partition. The key is to specify the owner in your mount command, thus:
sudo mount -o uid=pi,gid=pi /dev/sda1 /mnt/USB

This saves having to fiddle with fstab and such (obviously not everything can be automounted, but in this case it was quite simple).

You can find more info on the wiki at http://elinux.org/RPi_Adding_USB_Drives.

If you

sudo nano /etc/fstab

then add the line to the end

/dev/sda2 /mnt/usb vfat defaults 0 2

it should mount at boot, assuming the sda2 does not change, which it can if other drives exist at boot up.

A better option is to use uuid instead of /dev/
the uuid can be found using the following

ls -l /dev/disk/by-uuid/

or gparted has the same info

then your fstab line would start
UUID=long_hex_number_from_previous_command /mnt/usb vfat defaults 0 2

Using that method means it doesn't matter whether your drive comes up as sda1 or sdb2 or whatever if another drive is in when the Pi is booted.

I've always used uuid on all of my computers.

Stu

I went to find the UUID of the SD card I want to mount on start-up. You mentioned it should be a long hex number. However, when I execute the command, some of the drives have a long hex number, others are very short.

For example, my external drive shows up as "lrwxrwxrwx 1 root root 10 Jun 6 22:17 6135-3039 -> ../../sda1"

Other entries have long hex numbers such as "a0a67eb4-9835-424d-8b85-d97e960954e6" or "3a1c7ff4-3700-4fb1-9234-9de0cc1c9b45" in the same position of the entry.

Is the 6135-3039 the UUID?

[DougieLawson]

Is the 6135-3039 the UUID?

Yes for a FAT filesystem.

The simplest way to find UUID is with the blkid command.
