RAID5 and non RAID drive

[Jonas Jasas]

Hello,

We have DL360 with configured RAID5 (3HDD). I added 4th HDD that should work as regular drive (RAID5 must be as it was before). 4th HDD do not appear on device list. How can I make this 4th drive work?

Thank You!

The controller can only present RAIDs. Consider to create a RAID 0 on that drive.

So it is possible to create two partitions on single drive and make RAID0 on these partitions? I can do this using CD that comes with the hardware?

[Torsten. · Accepted solution]

I don't know what RAID controller you have, because I don't know the generation of your server. In general you create a RAID on disks (0, 1, 5, 6 or whatever), then you create logical drives on these RAID sets.

In your case you can create a RAID 0 on that single disk, then 1 or more logical drives (also RAID 0).

[Torsten.]

If you want and if it makes sense for your configuration, you can even add this new disk to the existing RAID 5.

You can create a RAID 0, on one drive only. You do not need 2 logical drives on the physical drive.

Just create a RAID 0, on the new drive.
