Operation
|

=========
|
||||
|
||||
Use this command to add a member disk partition to the RAID 1 set. Adding a
|
||||
disk partition to a RAID 1 set initiates mirror synchronization, where all data
|
||||
on the existing member partition is copied to the new partition.
|
||||
Before adding a brand new drive to a RAID 1 set, the drive must be formatted

.. opcmd:: add raid <RAID‐1‐device> member <disk‐partition>
|

Use this command to add a member disk partition to the RAID 1 set. Adding a

disk partition to a RAID 1 set initiates mirror synchronization, where all
|
||||
data on the existing member partition is copied to the new partition.

vyos@vyos:~$ add raid <RAID‐1‐device> member <disk‐partition>
|
||||
.. opcmd:: format <disk‐device1> like <disk‐device2>
|
||||
|
||||
Use this command to format a disk to be partitioned exactly like a second disk.
|
||||
The disk to be formatted must be inactive; that is, it must not have any
|
||||
partitions mounted and it must not already be part of an active RAID 1 set.
|
||||
In formatting, no data is copied to the formatted device, but any existing data
|
||||
on the formatted device is lost.
|
||||
This command is typically used to prepare a disk to be added to a preexisting

RAID 1 set (of which disk-device2 is already a member).
