OzTechGeek Posted August 10, 2015 Share #1 Posted August 10, 2015 Does anyone know how to verify via SSH that the correct value for "Advanced LUN allocation unit size" has been set on a volume? I have created 2 volumes on a test ESXi XPEnology install, both volumes are 64GB, I have set one volume to "4KB (Optimized for Windows ODX)" and the other to "8KB (Optimized for VMware VAAI)", but for some reason I cannot find a command line to verify that these settings have been applied, I have tried the following commands so far: blockdev --getbsz /dev/sdX blockdev --getss /dev/sdX cat /sys/block/sdX/queue/physical_block_size cat /sys/block/sdX/queue/logical_block_size cat /sys/block/sdX/queue/minimum_io_size cat /sys/block/sdX/queue/optimal_io_size cat /sys/block/sdX/alignment_offset I have tried the above commands on sda, sdb, md0, md1, md2 and md3. All commands provide the same numbers or am I missing something obvious. Thanks Link to comment Share on other sites More sharing options...
