This value should be set to the page size in bytes. The
|
||
|
|
default value of 4096 is the the most common page size for
|
||
|
|
most systems. If the sectorsize differs from the page size,
|
||
|
|
the created filesystem may not be mountable by the kernel.
|
||
|
|
Therefore it is recommended to leave this value at
|
||
|
|
4096. Unless you know that your kernel uses a different page
|
||
|
|
size. Suffix with k for power-of-two kilobytes.
