no Time Machine. No space left on device

[Allan Marcus]

After the latest FW upgrade, Time machine from the router has stopped broadcasting the mount point, and I see lots of "No space left on device" messages.

Time Machine is pointed to an external USB drive.

From the logs above, it looks like you've exhausted the flash memory on your router.

If others don't give an intermediary fix, a full reset to factory defaults should bring it to having some free space after a minimal and manual configuration to secure the router and connect to your ISP.

Please see my signature for the M&M Config link and further details.

Thanks L&LD. I'm a little confused. Only .dev.root is full. I assumed that the merlin firmware uses that space appropriately. All the other partitions seem to have plenty of space left. Is in uncommon to have no space left on root?

If I'm remembering what I read just a few days ago correctly, .dev.root is read-only. There is no free space there (ever).

I may have been wrong in my first post above.

well, I installed the RT-AC68U_384.10_2 firmware, which forced a reboot (of course), and it's working again. Odd. Very odd.
