While growing filesystems < 2TB (on FreeBSD 6.2-STABLE) works (even =20
with negative superblocknumbers in the output)
it seems impossible to grow larger filesystems:
Trying to grow a filesystem from ~4TB to ~6TB on a disk with a GPT =20
(single partition)
start size index contents
0 1 PMBR
1 1 Pri GPT header
2 32 Pri GPT table
34 14648432573 1 GPT part - FreeBSD UFS/UFS2
14648432607 32 Sec GPT table
14648432639 1 Sec GPT header
growfs fails:
growfs: we are not growing (2197264879->440882671)
What are the limits, are they bound to the largest possible bsdlabel =20
(i.e unsupported beyond 2^31-1 Sectors) ?
Is it possible to grow such a filesystem ?
What am i doing wrong ? Hints appreciated.
Henry
