Hi,
I have been playing kernel mont to UBIFS rootfs volume for several
days, the kernel can now mount to UBIFS volume root, the system
services were running fine except the connection manager connmand
service failed, I restarted it again and again, the connman was always
crashed and ubifs_read_node: bad node type. Despite the UBIFS errors,
the system could be still running, I could type shell comands in
console when connman was stopped.
I am not clear if UBIFS errors caused connman failure or connman
caused UBIFS error, and why it always failed in connman, was it
coincident or was some special in connman man link to other things
such as udev to cause the issues?
Let me make it clear, it did not happen when the UBIFS rootfs was not
in UBIFS volume, so something was not right in UBIFS volume mounted
root, what could that be?

Have you enabled the stats file feature in ConnMan? It's enabled on
default. Try again with '--disable-stats' and check if it makes a
difference.
Background: ConnMan save networking stats into a ring buffer file. The
file write operations are done via a mmap'ed memory. To avoid data
loss a double buffering approach with an 'atomic' swap is used:
stats_file_unmap(history_file);
stats_file_unmap(temp_file);
close(temp_file->fd);
unlink(history_file->name);
err = link(temp_file->name, history_file->name);
unlink(temp_file->name);
close(history_file->fd);
stats_file_cleanup(history_file);
stats_file_cleanup(temp_file);
IIRC, f2fs is known not to work. Maybe there is also some limits on
ubifs as well.
Thanks,
Daniel
