Alexander Motin 3e0d106077 Increase MAXPHYS from 128KB to 1MB.

ZFS by default allows record sizes and I/O aggregation up to 1MB.
Having MAXPHYS below that causes I/O fragmentation and respective
maximum queue depth reduction for disks.  First creates additional
processing overhead, while second may limit disk's ability to sort
the I/Os for better performance.  AFAIK Linux has no such limitation,
so being on par is good to unify ZFS I/O scheduler tuning.

Increased MAXPHYS may consume additional memory for different memory
structures and page lists, but for typical NAS memory size it should
not be a big problem.

Building FreeNAS 11 from Scratch

Note: All these commands must be run as root.

Requirements:

Hardware
- CPU: amd64-compatible 64-bit Intel or AMD CPU.
- 16GB memory, or the equivalent in memory plus swap space
- at least 80GB of free disk space
Operating System
- The build environment must be FreeBSD 11.x (or 11-STABLE) (building on FreeBSD 10 or 12 is not supported at this time).

Make Targets

checkout creates a local working copy of the git repositories with git clone
update does a git pull to update the local working copy with any changes made to the git repositories since the last update
release actually builds the FreeNAS release
clean removes previously built files

Procedure

Install git
```
pkg install -y git
rehash
```
Clone the build repository (/usr/build is used for this example):
```
git clone https://github.com/freenas/build /usr/build
```

Install Dependencies

cd /usr/build
make bootstrap-pkgs
python3 -m ensurepip
python3 pip install six

First-time checkout of source:
```
make checkout
```

A FreeNAS release is built by first updating the source, then building:

make update
make release

To build the SDK version:

make update
make release BUILD_SDK=yes

Clean builds take a while, not just due to operating system builds, but because poudriere has to build all of the ports. Later builds are faster, only rebuilding files that need it.

Use make clean to remove all built files.

Results

Built files are in the freenas/_BE subdirectory, /usr/build/freenas/_BE in this example.

ISO files: freenas/_BE/release/FreeNAS-11-MASTER-{date}/x64/.

Update files: freenas/_BE/release/.

Log files: freenas/_BE/objs/logs/.
