Additional HDD 3TB recognized as 2 TB. [Solved]

[iT!T]

Hi,
I'm running Proxmox on HP 800 G1 SFF. Recently i added additional HDD HGST 3TB. I tried to add it to my server following this tutorial https://bit.ly/2kMr5uV , but Proxmox recognised it as 2TB only, can anyone help me with that?

2 TB (or 2.3 TB) is a magic number for storage. Some older controllers are not able to handle such big disks. I encountered this myself with older HP(E) hardware raid controllers and had to replace it with a newer one. Maybe this is also the case for your machine.

Hi, thanks for replay. I've seen exact same PCs being sold with 3TB drives, so I blieve it's probably something with my Proxmox config.

There is no configuration for limiting disk sizes.

Please install lsscsi with apt-get install -qq lsscsi and report back the command output of lsscsi --size in CODE tags:

report back the command output of lsscsi --size

Thank you. Done that, result is underhere:

Maybe I did something wrong during formatting process?

Without knowing what you did, it's hard to tell.

Can you also please post the output of lsblk?

I fallowed tutorial from my first post (https://bit.ly/2kMr5uV ). I removed partition in fdisk, and trying once more. Can't set bigger partition than 2TB

But proxmox itself sees the proper size.

Here it is.

Your probably formating with MBR, your need to set the partition table to GPT, then you should have no issue creating the full 3TB partition.

Thank you for replay. Proxmox is new to me, could you please give me some hints how to do it?

parted /dev/sdb
mklabel GPT
mkpart data ext4 primary 2048s 100%

 

[iT!T]

I did it! Thank you sg90!

I had some problems with "mkpart data ext4 primary 2048s 100%" command, so I did it a bit different using parted, and it worked.
Thank you!
