Jolicloud USB problem

[Alecmag]

I have jolicloud installed, and everything seems to be working, but when I plug in a USB and go to the drives section, it shows my usb, but it's grayed out and I can't click it.

Anyone know what to do about this?

It seems many people have an error in the file /etc/fstab, which is causing the mount problem.

Open a terminal, and do

gksudo gedit /etc/fstab

to open the file as root.

There should be a line that looks something like

/dev/sdb1 /media/cdrom0 udf,iso9660 user,noauto,exec 0 0

Comment that line out with a # so it looks like

# /dev/sdb1 /media/cdrom0 udf,iso9660 user,noauto,exec 0 0

And restart.

I have a friend with jolicloud, so I'll double check the exact line when I get a chance.

It didn't seem to make a difference. Still boots up the same way.

Can you post the contents of /etc/fstab

Also, plug in a USB drive, open a terminal and post the output of

dmesg | tail
sudo fdisk -l

[Alecmag]

"dmesg | tail
sudo fdisk -l" gives me:

Can you post the contents of /etc/fstab as well?

While we try and figure this out, you can mount the disk the old fashioned way

make a directory for it, in this case I'm naming it usb.

sudo mkdir /mnt/usb

and mount

sudo mount /dev/sdb1 /mnt/usb

and you can now navigate to /mnt/usb to access your drive.

Unmount as so

sudo umount /mnt/usb

[nmset]

#Please post the output of
mount
#with the USB plugged in

#Try this
mkdir /var/tmp/J
mount -t auto /dev/sdb /var/tmp/J
#If no errors
mount
ls /var/tmp/J

#If nothing does
#Unplug
halevt
#Plug in

I don't use Jolicloud, just gave it a shot recently, so I don't know if it uses HAL at all, may be not, in which case halevt will be missing.
It seems from the previous messages that you just can't mount the USB drive, you should try manual mounting as root or through sudo.
