Hi All, Does anyone know how to get the actual block size used by an osd? I’m trying to evaluate 4k vs 64k min_alloc_size_hdd and want to verify that the newly created osds are actually using the expected block size. Thanks, -TJ Ragan

ceph osd metadata osd.<osd_num> | jq '.bluestore_bdev_block_size' k
