Hi,
Carambola devices use mtd partitions, but I don't have enough knowledge on how to track IO activity, especially amound of bytes written and number times that "erase blocks" command got used.

I know that mtd device isn't a block device, but what confuses me that I see mtdblock devices also. But I still can't see number of these fake blocks being used

I have used iostat but it is not showing any changes on mtdblock5 partition which is mounted as /overlay jffs2 partition on Carambola 2.

I have also checked stats in /proc/diskstat, and they also only change for /dev/mmcblk0p1 which is external usb device, but not for any of mtdblockX partitions.

Can you please point me in the right direction?

Thanks in advance!
