Can't add second ssd to array


Recommended Posts

I'm trying to upgrade my single 250 ssd cache to dual 500GB. The problem is I can only add one of the 2 drives to the array "sdn".

The other one "sdo" I can see in the terminal using fdisk -l "see attachment". But its not showing up in the webui.

 

Any idea what could be causing that?

What do you mean by not showing up on the ui?

When the array is stopped You can add cache devices I can add 1 ssd but the second one is not showing up I would post a screenshot but I can't stop the array right now cause of parity check. I started a new config but that also didn't fix it.

The syslog shows that the system is getting errors reported trying to query /dev/sdo which probably explains why it is not showing up.   However I have no idea what is causing the errors.

Its a new drive so it should work but ok I will try it in another system and report back.

The problem is that both SSDs are identified the same:

Jul  2 19:03:21 NAS kernel: ata5.00: ATA-9: Intenso SSD, 3813450-531609030, O1217A, max UDMA/133
...
Jul  2 19:03:21 NAS kernel: ata6.00: ATA-9: Intenso SSD, 3813450-531609030, O1217A, max UDMA/133

This is very unusual, usually the serial number is part of the identification, e.g.

Jul  2 19:03:21 NAS kernel: ata1.00: ATA-8: WDC WD20EURS-63S48Y0,      WD-WCAZAA480715, 51.0AB51, max UDMA/133

 

Because of this you can only use one of these as an Unraid server assigned device.

There is no way around it?

Only if there is a firmware update that adds the serial to the id.

Well, forget that, according to the SMART report that is the serial:

 

Device Model:     Intenso SSD
Serial Number:    3813450-531609030

 

So both have the same serial, tha't not a real serial.
