Hi there,

Before Solaris 8, vmstat will always report in the free column the "minfree" 
after a prolonged time, because the filesystem cache simply eats all available 
RAM. It was all fine but makes it difficult to find out the memory utilization 
on the boxes. The only ways to find out is to check out sr column but that only 
tells you you don't have enough memory and leaves you in the reactive mode.

Solaris 8 introduced the cachefree list and suddenly vmstat starts to report 
meaningful free mem on the system. That was beyond great for sysadmins... Until 
ZFS came

Now that ZFS cache will  eat up all the free mem for cache, again that's all 
fine. But vmstat doesn't report meaningful free memory again. Yes memstat can 
tell you the ZFS file data size but who wants to run mdb every now and then?

Can we introduce some new kernel variable the way we introduced cachelist and 
make vmstat free memory report meaningful again?

If it makes sense I can open a new bug.

Sean
