02. After adding all of those disks as a members of the RAID 5 array, you can go further, click on Volumes > volumes groups
and add a new volume group.
03. Once the volume group created, you can go and create the array. Go to Volume > Software Raid, and click on the link “create new raid partition”
You should obtain a screen like the one bellow.. where you can easily choose your disks participating in the RAID 5 and create an array. In my case I choose to select all four 1 Tb SATA drives which I had in my system.
And finally you should obtain a screen like the one below. You can see that the array is in degraded state and the synchro did not started yet. But don't worry, it'll start automatically…..
04. Next thing is to format this array. For this go to the menu Shares > and click on the link “create new file system volume“.
You have a quite a few options there, I took the default one… XFS. But it does not mean that you can't choose EXT 3 or EXT 4… -:)
