How is the block size determined in z / OS NFS?

If BLKSIZE (0) is specified for Direct Access (DA) data sets, the system does not determine the block size. z/OS NFS Server uses a formula to calculate the block size; see blksize (0 | quan) in Data set creation attributes syntax. The BLKSIZE is also important to the performance of the z/OS NFS, which performs physical I/O on a block basis.

This is exactly the issue encountered in the opening quotation.

How is the size of a block related to BSZ?

Note that the block size is specific to the cur‐ rent file descriptor opening the block device, so the change of block size only persists for as long as blockdev has the device open, and is lost once blockdev exits. So BSZ reported by blockdev is neither logical nor physical block size.
