OK, I'm a complete newbie to unRAID, but think this is the solution I was looking for.  Everything set up correctly and was easy to navigate.  But, then I installed some of my larger drives and I started having problems.

 

I installed 2x 5TB drives with the thought that one would be the parity disk.  But, I found that unRAID was only showing these as 2.2TB despite the bottom of the screen showing that they are 5TB drives (see attached screen shots).  I tried reading some posts on this and it seemed like there was a 2TB limit until you purchased a license.  So, I purchased a license thinking that I would automatically start seeing the extra space on these drives ones properly registered.

 

Turns out, that is not the case.  Still at 2.2TB after a reboot.

 

Am I doing something wrong?  Do the drives need to be re-formatted or re-partitioned?  Any help is appreciated.

 

Motherboard:    Intel - S5000PSL with currently 8GB memory (I will be upgrading)

 

Thank you in advance.

Most likely, the onboard SAS / Sata controller (ESB2?) only supports up to the 2.2tb (not an uncommon occurance the older you go).  Possibly a BIOS update might help, but you're probably going to have to add in a PCIe HBA

OK, thank you for pointing me in the right direction.  I had previously thought it was a setup problem, but it seems like I have a hardware limitation now.

 

My mainboard has this SAS chip embedded: LSI SAS1046E

 

Founnd elsewhere on the web in relating to this controller:  "The big problem with the 3Gbps cards is the 2TB size limit."

 

So my next question leads me into new uncharted territory:  What should I be looking to buy for my server?  Assuming an SAS card of some sort?

 

Thank you for your quick response and in advance for any other help...

I personally use a SuperMicro SAS2LP-MV8, but most LSI based controllers will work (just need to flash them to IT mode)  Just look in the hardware sub forum and you'll see lots of recommendations
