The following commands give the block size
select max(lebsz) from sys.x$kccle;
(Note: The log block size is the unit for the setting of the log_checkpoint_interval, _log_io_size and max_dump_file_size parameters)
$ fstyp -v /dev/dsk/c1d0s6 | grep devbsize
$ df /opt/oracle
/opt/oracle (/dev/dsk/c1d0s6 ):42448742 blocks 6413020 files
DO NOT USE THE FOLLOWING :
df -g grep 'block size'
(Note: the available & used free blocks given by the command df -g are based on the OS block size -see list above ; also use the first 2 methods to find- not the BLOCK SIZE value returned by df -g )
