Hi All,
Back at SC16 I was told that GPFS 4.2.3.x would remove the “a sub-block is
1/32nd of the block size” restriction. However, I have installed GPFS 4.2.3.1
on my test cluster and in the man page for mmcrfs I still see:
2. The GPFS block size determines:
* The minimum disk space allocation unit. The minimum amount
of space that file data can occupy is a sub‐block. A
sub‐block is 1/32 of the block size.
So has the restriction been removed? If not, is there an update on which
version of GPFS will remove it? If so, can the documentation be updated to
reflect the change and how to take advantage of it? Thanks…
Kevin
