[SOLVED] Can't add a third drive to DSM 5.0


Recommended Posts

Posted (edited)

Hello,

 

I've followed a tutorial to install XPEnology on an HP Proliant N54L. The installation went without major problems, and covered everything up to the installation of a single 2To disk.

 

I then installed by myself a second 2To disk to DSM, without any problem (so I have a single volume with two 2To disks, using SHR).

 

Now I'm trying to add a third disk to the Raid, and I'm unable to do so. The disk is seen by ESXi and I can add it to the VM (it then says I have 5.46To available for the Diskstation VM), but when I'm in DSM, the third disk is nowhere to be seen :-/

I've tried several disks (I plan to have 4 * 2To disks in SHR in the end), and several ports, but the result is the same. I don't think it's a material problem, I must be doing something wrong...

 

I tried searching for another topic with the same problem, and "Trantor" asked for this :

 

~ # fdisk -l

The solution was a BIOS configuration, where SATA IDE Combined mode was enabled. In my case, it's Disabled.

 

Thanks for your help.

Sorry for the double post, but I think I've seen something interesting.

 

If I do the "fdisk -l" command via SSH not on ESXi, but directly on the Diskstation, I get this :

DiskStation> fdisk -l

So the third disk is seen here, but I don't see it in the graphical interface... I don't get it...

Well, I finally figured out my problem. When following the tutorial, someone pointed to a wrong dsm.pat file and I ended up installing DSM for DS214play, which is the "OS" for a NAS with only two hard drives... After upgrading to the correct 5.0 4493, I'm able to add my third drive.
