ZFS / arc_max

[Larry Rosenman]

After Peter Wemm's post yesterday that he fixed some of the SVN->CVS breakage,
I pulled a new csup of -CURRENT today.

I recompiled everything, and installed it.

It appears that something(tm) changed with regards to the vfs.zfs.arc_max
tuneable, and this number looks more reasonable than "all of memory":


vfs.zfs.arc_max: 4484431872

This is with 16G real in the box.

I've removed my setting of this to 8G (as it seems to be ignored anyway).

We'll see how the next few days goes.

(BTW, on the older kernel, setting vfs.zfs.arc_max to 8G allowed the machine
to stay up and do full backups, etc).

Please let me know of anything else you need.
