I use FreeNAS 11.2 to make iSCSI disk share.

I config esxi's iSCSI settings,then I can see FreeNAS iSCSI Disk in esxi's  Storage->Device. The esxi's version that I use is 6.7 update2.

I try to use the FreeNAS iSCSI Disk to create Vmfs Datastore.At last step,I click 'finish' , the following error occured.

Hi all

Is there anyone out there still having this issue? I'm experiencing the same behavior on a new TrueNAS Scale setup that is correctly configured as per above (zvol, etc etc). Everything was working 100% fine on VMFS6 on this server. I had to rebuild it and created the iscsi shares in exactly the same way as before (and the same way as a mirrored server that's still working) - but I can only create a VMFS5 datatsore, not VMFS6. If I try to do via the CLI, I get the same "invalid argument" error.

I'm running the latest release - TrueNAS-SCALE-22.02-RC.2

Any help gratefully received!

Many thanks

I delete the zvol.  Scrubbed the pool. Added the zvol back. using default options, 16k.  Confirmed by clicking advanced options.

Did the sharing and set the lun to 1.

My defaults for blocks were 512 as well.
