How to Duplicate the Hard Disk Drive

The ftdiskadm command duplicates the hard disk drive. Examples of duplicating Slot 2 and Slot 10 are
described here.
1. Log in to the server as the root user. If you login with graphical mode, select [Others...] to login.
2. Execute "3 Make Mirroring Arrays (RAID1)" of the ftdiskadm command, and set the desired partition in the
hard disk drive for which the slot number has been specified. The hard disk drive is duplicated automatically
after this setting.

may not be suitable as a boot device. If you plan to
store '/boot' on this device please ensure that
your boot-loader understands md/v1.x metadata, or use
--metadata=0.90


Tips For the slot number, refer to "1.1 Available Disk Configuration".

The ext4 file system can be created by default. The file system can be changed with
the commands such as mkfs.


Tips The allowable partition size is smaller than the actual hard disk drive capacity.

The actually secured partition size may be slightly different from the input value since
the partition is secured in accordance with the border of the hard disk drive cylinder.

Although division into up to 128 partitions is enabled, the load of the entire system
increases and the performance is lowered as more partitions are secured.
