the gstat is pretty cool. it shows something like this:
L(q) ops/s r/s kBps ms/r w/s kBps ms/w %busy Name
0 6 6 627 8.5 0 0 0.0 5.0| ad4
0 6 6 627 8.5 0 0 0.0 5.0| ad4s1
0 0 0 0 0.0 0 0 0.0 0.0| ad6
0 0 0 0 0.0 0 0 0.0 0.0| ad4s1a
0 0 0 0 0.0 0 0 0.0 0.0| ad4s1b
0 0 0 0 0.0 0 0 0.0 0.0| ad4s1c
0 0 0 0 0.0 0 0 0.0 0.0| ad4s1d
0 0 0 0 0.0 0 0 0.0 0.0| ad4s1e
0 0 0 0 0.0 0 0 0.0 0.0| ad4s1f
0 6 6 627 8.5 0 0 0.0 5.0| ad4s1g
how come there is ad4s1b and ad4s1c when those names don't appear in the
fstab or df?
thanks....
