I think this might be in the wrong forum, but since I am using a WRT1900ACv1 running r44467 I am posting the question here.
Now if I navigate to the Administration tab and scroll down to JFFS2 Support then choose 'Enable', choose 'Clean Internal Flash Storage,' click 'Apply Settings', then Reboot the router. The firmware then creates a Partition in the WRT1900AC on-board flash memory. This storage space is then accessed in the DD-WRT file system using the path /jffs.(aka Mounted at /jffs) This is when the Journaling Flash File System is actually managing this storage space.
Does that seem accurate?
So instead of enabling JFFS2 Support as described above I decide to do the following. I navigate to the USB tab of the Services page where I have enabled 'Core USB Support' and enabled 'USB Storage Support.' I have plugged in a USB Storage device into the USB port, or maybe a HDD plugged in via the eSATA port. There is a setting labeled 'Mount this Partition to /jffs' that you enter a UUID number of a partition on an attached USB storage device. That partition is mounted and accessible in the file system in the following path: /jffs.
This is where I find things get a little "fuzzy" based on forum posts and a few different wiki pages.
Now that the firmware has taken the partition on the USB storage device and mounted it to /jffs. (Again I have left JFFS2 Support disabled)
1) After mounting does the firmware also start/enable the Journaling Flash File System to manage that partition?
2) Is the partition just merely mounted for file system use without any special management?
To me where it says 'Mount this Partition to /jffs' means that it is only mounting the partition without any special management.
Which is correct? Or maybe is there another possibility I haven't considered yet?
