I think i expressed myself badly. I was already using one volume for
each 250k files. Now, with the 12 partitions, i was only setting each
volume to each partition... i was afraid the FTREE had some limits
over the volumes it hold.

Hum, i runned it today in /vicepa, after a night of filling one of the
big volumes (without errors this time)

1066 directories, 271316 files, 6385 directory pages
total file size        5990373849 bytes (5712.87MB)
average file size      22078 bytes
total directory size   8716348 bytes (8.31MB)
average directory size 8176 bytes
estimated RVM usage based on object counts, 48900776 bytes (46.64MB)
estimated RVM usage based on 4% rule,       239963607 bytes (228.85MB)

I already have seven more dirs as full as this one, each has it's own
volume on the same vicepa partition. if this will one eat 230MB of the
rmv, 230 * 7= 1610
So, i'd need 1.6GB?

Thanks,
Gabriel
