Not sure... but do realize that NFS is NOT a cluster aware filesystem. That is, it's not a shared filesystem... it's a network file system (NFS). The view of each client is not guaranteed. I guess you could say that NFS tries to keep from flying apart but doesn't try to keep every client's view integral. If you need true live shared storage, look into a cluster aware filesystem (e.g. ocfs2, GFS2, Veritas, etc.)

resize_lfs
RESIZE_LFS(8) BSD System Manager's Manual RESIZE_LFS(8)
NAME
resize_lfs -- resize a mounted log-structured filesystem
SYNOPSIS
resize_lfs [-v] [-s new-size] mounted-file-system
DESCRIPTION
resize_lfs grows or shrinks a mounted log-structured filesystem to the specified size. mounted-file-system is the name of the filesystem to
be resized, and new-size is the desired new filesystem size, in sectors. If new-size is not specified, resize_lfs will default to the cur-
rent size of the partition containing the filesystem in question.
When growing, the partition must be large enough to contain a filesystem of the specified size; when shrinking, resize_lfs must first
``clean'' the segments that will be invalid when the filesystem is shrunk. If this cleaning process results in these segments becoming
redirtied, this indicates that the given new size is not large enough to contain the existing filesystem data, and resize_lfs will return an
error.
EXAMPLES
To resize the file system mounted at /home to 32576 sectors:
resize_lfs -s 32576 /home
SEE ALSO
fsck_lfs(8), lfs_cleanerd(8), newfs_lfs(8)
HISTORY
The resize_lfs command first appeared in NetBSD 3.0.
AUTHORS
Konrad Schroder <perseant@NetBSD.org>
BUGS
resize_lfs should be able to resize an unmounted filesystem as well.
