Nas4Free and ZFS Tuning for 16gb Ram. This is my ZFS Config changes to smooth out network spikes with 16gb tested on both 64bit nas4free and 64bit openindiana 151a7 (openindiana/solaris are better at autotuning some of these settings; on these OS’s step 1 is not required). 1.
Edit the loader.conf file to set a heap of zfs variables (you will need to restart for these to take affect; the process differs between full and embedded installs. Please note these changes will be lost when you upgrade or reinstall. Full: use the file editor in the webui to edit /boot/loader.conf and add the below code to that file. Embedded: use these instructions and edit the /cf/boot/loader.conf file. loader.conf (rule of thumb is kmem size is set to 90% of total ram and arc min/max sizes are set to 75% of ram) ZFSTuningGuide - FreeBSD Wiki.

ZFS Tuning Guide (Work in Progress) To use ZFS, at least 1 GB of memory is recommended (for all architectures) but more is helpful as ZFS needs *lots* of memory. Depending on your workload, it may be possible to use ZFS on systems with less memory, but it requires careful tuning to avoid panics from memory exhaustion in the kernel. A 64-bit system is preferred due to its larger address space and better performance on 64-bit variables, which are used extensively by ZFS. 32-bit systems are supported though, with sufficient tuning.
History of FreeBSD releases with ZFS is as follows: 7.0+ - original ZFS import, ZFS v6; requires significant tuning for stable operation (no longer supported) 7.2 - still ZFS v6, improved memory handling, amd64 may need no memory tuning (no longer supported) 7.3+ - backport of new ZFS v13 code, similar to the 8.0 code 8.0 - new ZFS v13 code, lots of bug fixes - recommended over all past versions. . #! Creating and Destroying ZFS Storage Pools - Oracle Solaris ZFS Administration Guide. The following sections describe different scenarios for creating and destroying ZFS storage pools: Creating and destroying pools is fast and easy.
However, be cautious when performing these operations. Although checks are performed to prevent using devices known to be in use in a new pool, ZFS cannot always know when a device is already in use. Destroying a pool is easier than creating one. Use zpool destroy with caution. Creating a ZFS Storage Pool To create a storage pool, use the zpool create command. Creating a Basic Storage Pool The following command creates a new pool named tank that consists of the disks c1t0d0 and c1t1d0: # zpool create tank c1t0d0 c1t1d0 Device names representing the whole disks are found in the /dev/dsk directory and are labeled appropriately by ZFS to contain a single, large slice. Creating a Mirrored Storage Pool To create a mirrored pool, use the mirror keyword, followed by any number of storage devices that will comprise the mirror. ZFS.
