Hi again,

I'm painfully unable to understand how the same said « metadata 
over-commit » would allow, on my system, “df” to work properly on some 
filesystems and fail miserably on others.

AND show “100% full” filesystems with still more than 600 GB free... 
That would make quite much of an overcommit isn't it ?

So I wonder if there isn't something else or if the “overcommit” 
calculation is not really completely broke in the first place...
