OK, I've found the missing concept: DEFSIZE is 250M and I suspect that
the system thinks that all files are of that size. Changed the GC threshlds
to 30 and 40 percents and it started to free up the space. But it frees the
space very slowly: now it almost stopped at 3G of free space, while now there
is almost 700G of free physical space.
Also I've changed the defsize to 1M: does anyone knows, will it mean that
the maximal file size will be 1M, or it will grow to the actual file size?
