UBIFS size issue

Hello,

Thanks for reply,

I went through the links, it has mentioned about the free space i.e. "Use%" from below logs .

It also informs that how it varies. Following logs of mine is showing the same.

But I actually want to know that ,

when I create a volume by 55 MiB size and I get it as 49 MiB size after df -h, then

for what purpose 6 MiB (55MiB - 49MiB) is used ?

Why I could not able to see 55 MiB size, as allocated total space. ?

-- Following is the log -----

root@dhcppc7:~# df -h

Filesystem Size Used Available Use% Mounted on

ubi0:vol_1 49.2M 44.0M 5.2M 90% /

root@dhcppc7:~# sync

root@dhcppc7:~# df -h

Filesystem Size Used Available Use% Mounted on

ubi0:vol_1 49.2M 43.0M 6.2M 87% /
