Kernel 2.6.31+UBI/UBIFS at level ~3.10.y. In short summary what i see is: 1. Deleting a folder with a big file (680MB) in a partition of 892MB size. 2. Perform a sync. 3. Read available free space with statvfs, fails. It reports the same value as before deletion. 4. remount partition as ro, fails. But no message in dmesg. Is there any reason/bug known that would cause this behavior? I know this can happen, when there i an open filedescriptor to the file. So i verified and this is not the case for me.
