Diffrences between sys.forced.stripes and sys.forced.nstripes

Hello All,

We configure RAIN6 in our EOS storage with 7 FST (contains 16 disk in each FST). We make 16 group, each group contain 7 disk of each FST.

Now we configure raid6 in eos by using “eos -b attr set default=raid6 /eos/alicekolkata/grid/” and define 7 stripes i.e. " eos -b attr set sys.forced.stripes=7 /eos/alicekolkata/grid".
+++++++++++
[root@eos-mgm ~]# eos -b attr ls /eos/alicekolkata/grid/
sys.forced.blockchecksum=“crc32c”
sys.forced.blocksize=“1M”
sys.forced.checksum=“adler”
sys.forced.layout=“raid6”
sys.forced.nstripes=“6”
sys.forced.space=“default”
sys.forced.stripes=“7”
+++++++++++++++

But after configure raid6, the “sum(capacity)” and “capacity(rw)” value is same. Output of “eos -b space ls” is below:-
+++++++++
[root@eos-mgm ~]# eos -b space ls

Please suggest. Is there are anything is wrong?
