-I inode-size
Specify the size of each inode in bytes. mke2fs creates
128-byte inodes by default. In kernels after 2.6.10 and some
earlier vendor kernels it is possible to utilize larger inodes
to store extended attributes for improved performance. The
inode-size value must be a power of two larger or equal to 128.
The larger the inode-size the more space the inode table will
consume, and this reduces the usable space in the filesystem and
can also negatively impact performance. Using the default value
is always safe, though it may be desirable to use 256-byte
inodes if full backward compatibility is not a concern.
Extended attributes stored in large inodes are not visible with
older kernels, and such filesystems will not be mountable with
2.4 kernels at all. It is not possible to change this value
after the filesystem is created. |
