Sorry I didn't check the source code in gi= t, but from the "Details" below nothing leads me to believe that this FS is doomed to only be able to usefully utilize only ~86GB of the partition, and= not more. Are you ready to answer the flood of questions from people why their disk is only 62% efficient, and how to tune it to 100%? :-) Why use underscores instead of spaces? >=20 > Details: > Chunk-type Mode Allocated Used Free > ---------- ---- --------- -------- --------- > Data Single 4.01GB 2.16GB 1.87GB > System DUP 16.00MB 4.00KB 7.99MB > System Single 4.00MB 0.00 4.00MB > Metadata DUP 6.00GB 429.16MB 2.57GB > Metadata Single 8.00MB 0.00 8.00MB --=20 With respect, Roman ~~~~~~~~~~~~~~~~~~~~~~~~~~~ "Stallman had a printer, with code he could not see.
