Mount hard drives to a static location - coreflake - 5th Mar, 2013 08:18 PM

hey all,

i'm trying to mount my 2 external usb hard drives to a static location, but with no luck.
What i did was :

Code:

xbian@xbian ~ $ ls -l /dev/disk/by-uuid/

total 0

lrwxrwxrwx 1 root root 10 Jan  1  1970 01CDE506D37447B0 -> ../../sda5

lrwxrwxrwx 1 root root 15 Jan  1  1970 29b6c2f5-5469-49f2-abd5-daa9149021cc -> ../../mmcblk0p2

lrwxrwxrwx 1 root root 15 Jan  1  1970 8B12-9112 -> ../../mmcblk0p1

lrwxrwxrwx 1 root root 10 Jan  1  1970 CE3C43183C42FACB -> ../../sdb1

then checked :

Code:

xbian@xbian ~ $ cat /etc/fstab

proc            /proc           proc    defaults          0       0

/dev/mmcblk0p1  /boot           vfat    defaults          0       2

/dev/mmcblk0p2  /               ext4    defaults,noatime  0       1

/var/swapfile   swap    swap    defaults        0       0

and then :

Code:

sudo nano /etc/fstab

added these 2 lines :

Code:

UUID=01CDE506D37447B0 /media/usb0 vfat defaults,noatime 0 0

UUID=CE3C43183C42FACB /media/usb1 vfat defaults,noatime 0 0

but it doesn't seem to be working , does anyone know where i go wrong ?
Thanks !

- Keep in mind these drives have to be connected before boot

- Can you execute

Code:

sudo mount -a

and see if any errors pop up.

- This is also a nice guide: http://nwlinux.com/mount-hard-drives-in-etcfstab-using-uuid/

I am having the same issue.. I executed sudo mount -a before I started. Nothing came out. So good to get started. I first checked UUIDs and drive names (sda..):

Code:

xbian@xbian ~ $ sudo fdisk -l

Disk /dev/mmcblk0: 4025 MB, 4025483264 bytes

4 heads, 16 sectors/track, 122848 cylinders, total 7862272 sectors

xbian@xbian ~ $ ls -l /dev/disk/by-uuid/

total 0

lrwxrwxrwx 1 root root 15 Jan  1  1970 29b6c2f5-5469-49f2-abd5-daa9149021cc -> ../../mmcblk0p2

lrwxrwxrwx 1 root root 10 Mar 24 16:17 433523ac-11c3-44a0-b9f6-ee30aaab2a03 -> ../../sda2

lrwxrwxrwx 1 root root 15 Jan  1  1970 8B12-9112 -> ../../mmcblk0p1

lrwxrwxrwx 1 root root 10 Mar 24 16:16 8E37-FB11 -> ../../sda1

so the two partitions on my usbdrive are /dev/sda1 and /dev/sda2.

Now I edited fstab adding these two lines:

Code:

UUID=8E37-FB11 /media/SmallRyan  exfat defaults 0 0

UUID=433523ac-11c3-44a0-b9f6-ee30aaab2a03 /media/BigRyan ext4 defaults 0 0

and wrote it to the file. But now sudo mount -a gives me this error:

Code:

xbian@xbian ~ $ sudo mount -a

[sudo] password for xbian:

FUSE exfat 0.9.7

fuse: failed to access mountpoint /media/SmallRyan: No such file or directory

mount: mount point media/BigRyan does not exist

I followed the nwlinux.com guide.. but it didn't do the trick. What did I do wrong?

EDIT: I think I solved it, mounting harddisk/partition to "media/SmallRyan" means I first have to create such a folder!
So executed these two commands:

Code:

xbian@xbian ~ $ mkdir /media/SmallRyan

mkdir: cannot create directory `/media/SmallRyan': Permission denied

xbian@xbian ~ $ sudo mkdir /media/SmallRyan

xbian@xbian ~ $ sudo mkdir /media/BigRyan

xbian@xbian ~ $ sudo mount -a

FUSE exfat 0.9.7

xbian@xbian ~ $

So now it should work. I am not sure however if both Transmission, Flexget and XBMC have writing permissions..

EDIT: I thought this would do the trick but it doesnt:

Code:

xbian@xbian ~ $ sudo chmod -R 777 /media/SmallRyan

chmod: changing permissions of `/media/SmallRyan': Function not implemented

@coreflake
Try instead of using UUID to identify the disks, using "/dev/sda5" and "/dev/sdb1", if you always start the Raspy with the same drives connected it should work. To try it, just change it in the fstab file and execute the command "mount -a"
@zilexa
The error setting file permission is due to the file system of "SmallRyan", I recommend you change it to ext4, if it's not possible you must set permissions before mounting the drive. Add this options to fstab:

Code:

UUID=8E37-FB11 /media/SmallRyan  exfat defaults,uid=user,gid=group 0 0

[/term]
where user and group are the corresponding ones. You can also allow full access to by also adding umask=0.
I also recommend you add the option noatime (no access time) it speeds up the write/read speed and it's only necessary if you need the access time for your files (which isn't usual).

RE: Mount hard drives to a static location - zilexa - 25th Mar, 2013 07:15 PM

Trinket thanks for your help and tips. The reason I created one (small, 32GB) eXFat partition is for the theoretical situation that I want to connect my USB drive directly to my Mac or Win laptop because I need to transfer a big file and take it to a friend or somethin. Both dont support EXT4. Also, I can copy necessary files via XBMC File Manager to the eXFat partition and connect it to a Mac or Win pc.

It's just a safety measure I'd like to have. If I never use it and the EXT4 partition is filling up, I will delete the eXFAT partition and resize the EXT4 partition.

Just a follow up question about the best way to do static mount for an EXFAT partition:

@Trinkett did you mean I have to fill in an actual username and groupname?

RE: Mount hard drives to a static location - Trinket - 14th Apr, 2013 04:30 AM

Yep, I meant that! fill "user" and "group" with the ones you wish to grant access to! It can be either with the uid,gid (numbers) or just the name of them!
