Dear all,i have found a question about ubifs and sync !

Question is following;

What i do is just open an existing file in a UBIFS formated UBI volume
on a Nand Flash,

add a few lines to it ,close the file ,then without unmounting the
filesystem and reboot the filesystem.

When my board reboots and i looked at that file ,it's zero length and
has no contents.I suspect it's because

UBIFS does less frequent syncs .it just lost content of the file because
there's no sync before the reboot!

How can i solve this ?
