Hello Nab, It turns out that I'm impatient. The VMFS creation works but takes much longer than on rtsos or saniq for large volumes: Linus tip: 4 TB - 15 minutes 36 seconds 2 TB - 8 minutes 4 seconds 1 TB - 4 minutes 19 seconds 500 GB - 2 minutes 20 seconds 375 GB - 2 minutes 250 GB - 1 minutes 30 seconds 100 GB - < 1 minutes RTSos.x86_64-3.1.918: 4 TB - 26 seconds Any idea what is causing the additional latency?
