Explain how to persistent image works....

Hi  i installed the Switchfin on IP02...compiling all from the SVN.
Now to customize it i need to write our specific configurations in the IP02...(vlan...SNMP...)
I tried to understand the mtdblocks partitions and  structure but without success.

May someone help me to understand the structure and HOW i can write the files avoiding that the next reboot delete every conf files wrote.

Regards

Hi Serenissimo

All the SwitchFin configurations are kept inside the /persistent folder (this is mounted as writable) and each linked to the correct location at boot, so any changes to the configs will still be there after reboot.

Thanks

Please show me how can i write in definitive way on persistent file system and  mtdblock directory structure for Switchfin distro.

Thank you for your help

Hi Serenissimo

Please try the following SSH into your IP02
login using root/uClinux
run the following

Code:


echo "hello im your IP02" > /persistent/hello

reboot

after the system has rebooted re login and run

Code:


cat /persistent/hello

(you should see hello im your IP02 on the screen), if you cant "cat" /persistant/hello after reboot then there is an issue with your firmware.

Hi Guys,

To be sure that flash operation completes you may need to execute 'sync' command before the reboot
   
My five cents.
