Full filesystem - newfs -m 5.

Hi,

Sorry about the strange subject line, but here's the problem.

Today we had our /home disk reach 95%.

The disk was 'newfs'd with the command.
newfs -c 32 -i 32768 -m 5 -o space /dev/md/dsk/d2
d2 is a mirrored disk of
c1t9d0s7
c1t15d0s7

'metastat d2' says the disks are 'Okay'.
Now I believe that the '-m 5' option means that although the filesystem
may reach 100% (using 'df -k /home'), this is actually 95% of the total
disk allocated, so that
the 'root' user can login and 'clean-up' files.

Is there a way of confirming that there is 5% of 'root' space available
on this disk?
Is the '-m 5' option setup the way I thought it was?

Thank you
Craig.
