Solaris 10 -problem understanding swap space

edited Feb 3, 2012 12:10AM in Oracle Solaris File Systems and Disk Management (MOSC) 7 comments
I have 2 swap slices - 8GB and 3GB giving me a total 11GB swap.
root@sbc-san-01 # swap -l
swapfile             dev  swaplo blocks   free
/dev/dsk/c0d0s1     101,1      16 16777200 16777200
/dev/dsk/c0d0s7     101,7      16 6283248 6283008


However, when I run swap -s   I get the following:
root@sbc-san-01 # swap -s
total: 7747424k bytes allocated + 1407128k reserved = 9154552k used, 9119568k available

Running top gives me:
Memory: 12G real, 340M free, 8947M swap in use, 8871M swap free

I expected to see a figure close to 11GB in the swap -s and top output but there isn’t.
7747424k bytes allocated + 1407128k - gives 9154552k

Howdy, Stranger!
