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. -- CL Martinez carlopmart {at} gmail {d0t} com
