The man page you point out is for gfs1. The man page for mkfs.gfs2 doesn't have the "-b" option for blocksize. That goes to my point about documentation.

I don't know the answer to all your questions, but the blocksize is the first option in the man page of gfs_mkfs
# man gfs_mkfs
DESCRIPTION
gfs_mkfs is used to create a Global File System.
OPTIONS
-b BlockSize
Set the filesystem block size to BlockSize (must be a power of two). The minimum block size
is 512. The FS block size cannot exceed the machine's memory page size. On the most archi-
tectures (i386, x86_64, s390, s390x), the memory page size is 4096 bytes. On other architec-
tures it may be bigger. The default block size is 4096 bytes. In general, GFS filesystems
should not deviate from the default value.

Subject: gfs2 doc and performance question
I been trying to find documentation on gfs2. but it seem that there isn't
much.
Is there any detail documentation on gfs2?
Can one set the block size when creating gfs2 filesystem?
Has there been any performance benchmark of gfs2?
Thanks,
