mount: could not find any free loop device

You can see what is being used by a loop device with losetup:

  # losetup /dev/loop0

  /dev/loop0: [fd06]:234921356 (/linux/isos/backtrack.iso)

It is possible to increase the number of available loop devices. Free

all loop devices, and add a line with the following to

/etc/modprobe.conf:

     options loop max_loop=64

(maximum is 256)

Then, do:  

     rmmod loop && modprobe loop

If you get an error that the module couldn't be removed, you still have loop 

devices in use.

Newer kernels (2.6.21 or 2.6.22) use a dynamic allocation of loop devices, 

so you will only have to create the filesystem representation of the devices:

  for ((i=8;i<64;i++)); do

    [ -e /dev/loop$i ] || mknod -m 0600 /dev/loop$i b 7 $i

  done

Happy Pi Day!

And don’t forget 6:28pm (Tau Time)!

Future Holidays to look forward to:

• March 14, 2015 = Pi Day (to 4 decimal places)
• April 4, 2016 = Square Root Day
• 6:02am on October 23, 2012 = Mole Day (6:02 10/23)

Swap Your Laptop for an iPad + Linode

Here's an excellent Linux Journal Article which talks about using an iPad with a Bluetooth keyboard, to ssh into a Linux host:

The Linux host is a virtualized node in "the cloud":

Linode: http://www.linode.com/

And the SSH client for iPad can be found here:

iSSH for iPad app: http://itunes.apple.com/us/app/issh-ssh-vnc-console/id287765826?mt=8


I've tried this app on my iPad and I think this works a lot better than I thought it would!
