Hi all,
I have installed FreeBSD 8.3 amd64 release in an ESXi server. Due to
some limitations, I can only assign 2GiB of RAM to this virtual machine
and I need to use ZFS as filesystem to store some data (MySQL databases).
According to http://wiki.freebsd.org/ZFSTuningGuide I have configured
some options:
vfs.zfs.write_limit_override=268435456
kern.maxvnodes=250000
According to ZFS version, FreeBSD 8,3 comes with version 28, and
reading previous guide there is not need to adjust nothing more.
But what about l2arc options?? Do I need to adjust vfs.zfs.arc_max and
vm.kmem_size options?? How can I calculate these values??
Thanks.
