Using mkfs Command to Create File System Might Fail
on Very Large Disks (6352813)
The mkfs command might be unable to create a le system on disks with a certain disk
geometry and whose sizes are greater than 8 Gbytes. The derived cylinder group size is too large
for the 1-Kbyte fragment. The large size of the cylinder group means that the excess metadata
cannot be accommodated in a block.
The following error message is displayed:
With 15625 sectors per cylinder, minimum cylinders
per group is 16. This requires the fragment size to be
changed from 1024 to 4096.
Please re-run mkfs with corrected parameters.
Workaround: Use the newfs command instead. Or, assign a larger fragment size, such as 4096,
when you use the mkfs command.

■
The following message is displayed:
0% done: 0 pages dumped, compression ratio 0.00, dump failed: error 6
Workaround: Congure the size of your system's dump device to less than 1 Tbyte.
