.SH NAME
fsba \- file system block analyzer
.SH SYNOPSIS
.B fsba     
file-system ...
.SH DESCRIPTION
.I Fsba\^
determines the number of extra sectors
(1 sector has 512 bytes)
needed when the file system logical
block size is increased from 512 bytes
per block to 1024 bytes/block.
.I File-system\^
should be specified by device name (e.g.,
.BR /dev/rp11 ).
.PP
.I Fsba\^
determines how many sectors are currently
allocated for the 512 bytes/block file system,
and how many sectors will be required for the
1024 bytes/block converted file system.
.I Fsba\^
also prints out the number of  allocated
and free i-nodes for each
.I file system.\^
.PP
If the number of free sectors
for the 1024 bytes/block file system 
is negative, this indicates the file-system 
is too large to convert to 1024 bytes/block.
