https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=276524 --- Comment #3 from balchen@ste.no --- Hi Alexander. I hope this is a better illustration of the issue. As you can see, the logical block size reported to ESXi is always 512, but the physical block size is 4K when set to 4K, and 8K when set to 512. volblocksize=8K LUN Block Size=4K LUN Physical Block Size=<blank> [root@localhost:~] esxcli storage core device capacity list Device Physical Blocksize Logical Blocksize Logical Block Count Size Format Type --------------------------------- ------------------ ----------------- ------------------- ----------- ----------- t10.FreeBSD_MYDEVID00000000000000 4096 512 3865470576 1887436 MiB Unknown volblocksize=8K LUN Block Size=512 LUN Physical Block Size=<blank> [root@localhost:~] esxcli storage core device capacity list Device Physical Blocksize Logical Blocksize Logical Block Count Size Format Type --------------------------------- ------------------ ----------------- ------------------- ----------- ----------- t10.FreeBSD_MYDEVID00000000000000 8192 512 3865470576 1887436 MiB Unknown -- You are receiving this mail because: You are the assignee for the bug.
