Data not freed after remove?

[Sven Eisenberg]

Hi MTD list

I've seen a problem on our embedded device with UBI/UBIFS. 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.

Thanks in advance, Sven Eisenberg
