To repair RAID-5 volume

1. Click the RAID-5 volume you need to repair, and then click Repair RAID. The RAID-5 volume

whose member has failed is in the Data Redundancy status.

2. Select the target disk where the reconstructed data will reside. The unallocated space on the

target disk has to be at least the size of the RAID-5 volume member. If you select a basic disk, it

will be automatically converted to dynamic.

3. Click OK to add the pending repairing RAID-5 volume operation.

The results of the pending operation are immediately displayed as if the operation had been

performed.

To perform the pending operation you will have to commit it (p. 24). Exiting the program without

committing the pending operations will effectively cancel them.

Important! If this operation was performed with machine rebooting or by using bootable media, the dynamic

volume will get the Failed redundancy status after booting into any edition of Windows 2003. To repair the

dynamic volume, reactivate the underlying disks by using Windows Disk Management functionality – see the

Troubleshooting Disk Management article on the Microsoft Web site.

6.26 Specifying i-node density

This operation applies to volumes whose file systems are Ext2 or Ext3.

The i-node is the main data structure for Linux Ext2/Ext3. All of a files information, with the

exception of its actual name and data, is stored in the i-node. Each file has its own i-node. Each i-

node contains a file description, including number, file type, size, data block pointers, etc. Space for i-

nodes is allocated when you install the operating system or when a new file system is created. The

maximum number of i-nodes, and hence the maximum number of files, is set at file system creation.

Running out of i-nodes prohibits the creation of additional files and directories on the volume even if

there is sufficient disk space. I-nodes themselves consume disk space, so specifying the i-node

density lets you organize disk space in the optimal way. I-node density is determined by specifying

the number of bytes per i-node. Usually, the default value is 4096 bytes per i-node.

Important: If you change the i-node density of a boot volume the operating system will become unbootable. To

restore the system bootability use a boot loader.

To specify i-node density

1. Right-click the Ext2/Ext3 volume, and then click Change i-node density.

2. In Bytes per i-node, specify the required value.

 Use lower i-node density (that is, increased Bytes per i-node value) for a volume that

contains just a few large files. This will allocate more space for files and less for i-nodes. The

less i-nodes there are the in the system, the faster the “file system check” operation will be

performed.

 Use higher i-node density (that is, reduced Bytes per i-node value) for volumes that contain a

large number of small files. This will allocate more space for i-nodes and less for data. The

more i-nodes there are in the file system, the less likely you will not run of i-nodes. But, the

“file system check” operation will be performed slower.

3. Click OK to add the pending i-node density changing operation.

The results of the pending operation are immediately displayed as if the operation had been
