VM system has a fresh 8.0-STABLE-201002 installed on it, taken from the
8.0-STABLE snapshots directory. This is "fairly close" to your
kernel/world build time.
testbox# uname -a
FreeBSD testbox.home.lan 8.0-STABLE-201002 FreeBSD 8.0-STABLE-201002 #0: Tue Feb 16 21:05:59 UTC 2010 root@mason.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC amd64
Things to note up front:
1) I chose *not* to install ports nor src from the installation medium,
so /usr/src and /usr/ports at this point are empty dirs.
2) VM instance is running without ntpdate + ntpd intentionally.
Preparation and creation of the zpool (raidz1 w/ 3x 8GB disks) and
filesystems:
testbox# echo 'zfs_enable="yes"' >> /etc/rc.conf
testbox# /etc/rc.d/hostid start
Setting hostuuid: 564de564-be17-6e27-89b6-ae662003f0db.
Setting hostid: 0xfa4c1c12.
testbox# /etc/rc.d/zfs start
testbox# zpool create data raidz1 da1 da2 da3
testbox# zpool list
NAME SIZE USED AVAIL CAP HEALTH ALTROOT
data 23.9G 141K 23.9G 0% ONLINE -
testbox# zfs set mountpoint=none data
testbox# zfs create -o mountpoint=/usr/obj data/usr_obj
testbox# zfs create -o mountpoint=/usr/ports data/usr_ports
testbox# zfs create -o mountpoint=/usr/src data/usr_src
testbox# zfs list
NAME USED AVAIL REFER MOUNTPOINT
data 228K 15.7G 24.0K none
data/usr_obj 24.0K 15.7G 24.0K /usr/obj
data/usr_ports 24.0K 15.7G 24.0K /usr/ports
data/usr_src 24.0K 15.7G 24.0K /usr/src
At this point I tuned loader.conf to permit for larger ZFS ARC size (the
VM is only allocated 1GB of RAM; this is intentional, as I wanted to
simulate a memory-tight environment), explicitly disabled prefetching,
and adjusted vfs.zfs.txg.timeout for an increase in responsiveness:
testbox# echo 'vm.kmem_size="768M"' >> /boot/loader.conf
testbox# echo 'vfs.zfs.arc_max="512M"' >> /boot/loader.conf
testbox# echo 'vfs.zfs.prefetch_disable="1"' >> /boot/loader.conf
testbox# echo 'vfs.zfs.txg.timeout="5"' >> /boot/loader.conf
testbox# shutdown -r now
System rebooted to pick up loader.conf changes, and on to csup:
testbox# csup -h cvsup10.freebsd.org -L 2 -4 /usr/share/examples/cvsup/stable-supfile
{...}
testbox# csup -h cvsup10.freebsd.org -L 2 -4 /usr/share/examples/cvsup/ports-supfile
{...}
Removing some base system pieces and adding optimisations:
testbox# cat > /etc/make.conf
KERNCONF=GENERIC
CPUTYPE?=nocona
testbox# cat > /etc/src.conf
WITHOUT_IPFILTER=true
WITHOUT_LIB32=true
WITHOUT_KERBEROS=true
WITHOUT_PROFILE=true
WITHOUT_SENDMAIL=true
testbox#
Builds are underway now (following /usr/src/Makefile method), I'll
report back when those are done. I'm also adding "time" in front of the
"make buildXXX" portions just to see now long things take.
