In fact, I retried to type these commands :

address@hidden:~# swapon
Usage:
 swapon -a [-e] [-v] [-f]             enable all swaps from /etc/fstab
 swapon [-p priority] [-v] [-f] <special>  enable given swap
 swapon -s                            display swap usage summary
 swapon -h                            display help
 swapon -V                            display version

The <special> parameter:
 {-L label | LABEL=label}             LABEL of device to be used
 {-U uuid  | UUID=uuid}               UUID of device to be used
 <device>                             name of device to be used
 <file>                               name of file to be used

address@hidden:~# mkswap /swapfile1
Setting up swapspace version 1, size = 524284 KiB
no label, UUID=76dccdc9-cb8a-40c6-9e0a-ed58eaa900f8
address@hidden:~# chown root:root /swapfile1
address@hidden:~# chmod 0600 /swapfile1
address@hidden:~# swapon /swapfile1
Adding 524284k swap on /swapfile1.  Priority:-1 extents:246 across:1568156k SS

Now it works.

shall I follow to do the different instructions mentioned on this website http://www.cyberciti.biz/faq/linux-add-a-swap-file-howto/ ie making swap file on the root

or shall I connect usrp to an external memory ? If yes shall I connect a flash disc to the usrp on its usb host port ?

Best regards,

Wafa HAJ HMIDA

Hi Wafa,

address@hidden:~# swapon /swapfile1
*swapon: /swapfile1: swapon failed: Device or resource busy*


The file is still opened; maybe you're already using it (check with
"swapon" without arguments)?
Have you been able to run mkswap on the file?

Also, you must use an external drive to store the swap file instead of
the root folder ( / ), because in the standard image on the standard 4GB
flash drive that the E100 uses, there won't be enough free space for a
reasonably large swap file.

Regarding question 2: swap can't be too big. Aim for 3-4GB.

Greetings,
Marcus
