ESXi 6.7U1 - Cannot create Datastore

[DartusTHMP]

Hello all,

On fresh installation I'm trying to create datastore on bellow drive and after selection of free space on left first thing I do not understand, why there is any VMFS partition (on right) when on before (on left) there is none and it even has almost same size as "Free Space" on left

When I try to create partition like this with any size like for examle 40GB pm mext screen it looks like this and instead of VMFS it will mark it as basic data:

After click of finish it will write following error:

Here is dump of vmkernel.log:

Here is also my setup as it is showed on main screen of WebGUI:

Can you please help me with it? I tried to google it but common guides like change of MTU and simillar didn't helped me. Also tried to reinstall it several times but issue is still there.

It looks like you are using NVMe SSD drive. can you check the compatibility and update to latest driver. Check vmkernel and hostd log when creating datastore

You can check this as well

thanks,

what size is your nvme ? 1.2TB ?

seems like installer has always created a 1.09tb datastore1 with vmfs6, so you have no space left to create another datastore

Thank you for you answer. I tried last desperate thing which I totaly forgot about which was installation of ESXi v6.7u3 and it resolved the problem. Now on both NVMe SSDs I'm able to create VMFS partitions without any problems.
