Re: Max FS Block Size.
Under LVM, it's
# newfs -F vxfs -b 16384 /dev/vgXX/rlvolY
The default is 1024 for file systems less than 8 gigabytes, 2048 for file systemsless than 16 gigabytes, 4096 for file systemsless than 32 gigabytes, and 8192 for larger
file systems.
Volume manager 3.2 may change the syntax somewhat but it will still be doable.

SolutionIn vxfs block size can be
>= 1024 & <= 8192 in powers of 2. So it appears that NO you can't have a 16K block size. 8 is the largest.
You define block size in the newfs command with -b xxxx where xxxx=the desired size
The defaults are as follows
FS size
<= 8GB => 1024
8.1 -> 16 Gb => 2048
16.1 -> 32 Gb => 4096
> 32Gb => 8192
Rgds,
Jeff
