Hi,

 

I'm using armbian on my Cubieboard running from nand. I'm just curious how do you implement wear-leveling in this armbian on nand implementation on ext4?

 

Thanks in advance.

• /tmp & /log = RAM, ramlog app saves logs to disk daily and on shut-down (Wheezy and Jessie w/o systemd)
• automatic IO scheduler. (check /etc/init.d/armhwinfo)
• journal data writeback enabled. (/etc/fstab)
• commit=600 to flush data to the disk every 10 minutes (/etc/fstab)

It's the same as on SD card except without data=writeback ... It can be done harsher but on behalf of security.

Hi Igor,

 

Got it.

But how about bad blocks management? Does it include some tool to scan and manage bad blocks?

If it's about a Cubietruck then I would start reading here:
