If IPFire is installed on a raid array then the following status should be seen
This shows that the array is a raid1 array named md127 and made up of two devices, sda and sdb
The "Personalities" line tells you what RAID level the kernel currently supports. In the case of IPFire it only supports Raid1 currently.
The next line means we're looking at the device /dev/md127.
It is active or 'started'. An inactive array is usually faulty.
It is a raid1 array and the component devices are:
[UU] represents the status of each device, either U for Up or _ for Down, so the above status shows that both devices are up and working as a Raid1 array. If [U_] or [_U] is shown then action needs to be taken to fix the faulty drive.
Any actions on the raid array will have to be carried out from the console command line. See the mdadm help command below.
[root@ipfireAPU ~]# mdadm --help mdadm is used for building, managing, and monitoring Linux md devices (aka RAID arrays) Usage: mdadm --create device options... Create a new array from unused devices. mdadm --assemble device options... Assemble a previously created array. mdadm --build device options... . . . For detailed help on the above major modes use --help after the mode e.g. mdadm --assemble --help For general help on options use mdadm --help-options
If IPFire is not installed on a raid array then the status page will show:
To have IPFire running on a raid array this has to be defined in the installation step.
See the Raid Array section in Step3: Run the installer
