zvol with block size 128kb or above.

[inbusine...@gmail.com]

I create zvol with block size 1MB on TrueNAS SCALE 23.10.1.3 then ESXi 8.0.2 create VMFS6 successfully.

Because of TrueNAS SCALE have a extent option Disable Physical Block Size Reporting that help create VMFS6 successfully.

Here are some configuration in  /etc/scst.conf on TrueNAS SCALE 23.10.1.3.

HANDLER vdisk_blockio {
    DEVICE lun011 {
        filename /dev/zvol/storage/lun011
        blocksize 512
        lb_per_pb_exp 0
        read_only 0
        usn b3c0aa94c09710f
        naa_id 0x6589cfc0000006463dbc9caeac71a888
        prod_id "iSCSI Disk"
        rotational 0
        t10_vend_id TrueNAS
        t10_dev_id b3c0aa94c09710f
    }

You can find lb_per_pb_exp=0 option.

In ESOS, how to add a such option in ESOS shell via CLI?

I found SCST 3.8.0 release notes below.

https://github.com/SCST-project/scst/releases

SCST Target 3.8.0 include

scst_vdisk: Introduced the lb_per_pb_exp attribute, allowing control over
whether READ CAPACITY 16 returns LOGICAL BLOCKS PER PHYSICAL BLOCK EXPONENT.

this attribute equal to TrueNAS SCALE 23.10.2 Disable Physical Block Size Reporting option.

Could you build a new ESOS distro with SCST Target 3.8.0?

If you don't have a time to update SCST target 3.8.0, I want to build it manually.

How can I build a new distro image with SCST 3.8.0?
