Partition type window

4. By

clicking

OK

in the Partition type window, you'll add the pending operation of

partition type changing (your actions may only undo or modify an existing operation,
See 3.4.5 «Modifying pending operations»).

Attention! Changing partition type might prevent some operating systems from working

with it, even if it is a compatible file system!

Changing partition type in Windows 98/Me can hide a partition and change the order of

letters assigned to other partitions. As a result, some shortcuts might stop working. A

detailed discussion of partition letter assignment rules for various operating systems

appears in 4.1 «Creating A New Partition».

Resizing i-node table in Linux Ext2/Ext3

In Linux Ext2/Ext3, the i-node index descriptor is the main data structure describing files.
Each descriptor contains a file description, including file type, size, data block pointers,
etc. Data block addresses reserved for a file are stored in its index descriptor.
The space for all i-nodes must be allocated in advance (at formatting). In the Ext2/Ext3
file systems, the maximum number of files is set at formatting.
The «bytes per a single i-node» value indicates the average partition file size. If there are
many small files, there must be many descriptors, each of which occupies some space.
Large files require fewer descriptors.
Acronis Disk Director Server enables you to resize i-node tables of existing partitions to
change the maximum file amount on them.

If you need to resize an i-node table of an existing Linux Ext2/Ext3 partition:

1.

Select a disk and Linux Ext2/Ext3 partition from the list in the Acronis Disk Director
Server main window.
