The machine is a Dell Optiplex 3020MT with the following specs:
FreeBSD was installed to the system using ZFS on the boot drive. A zfs pool was created on the two hard drives with:
zpool create -f -o ashift=12 -m /var/nas nas mirror /dev/ada1 /dev/ada2
Periodic maintenance is done by copying /etc/defaults/periodic.conf to /etc/periodic.conf and editing it to include regular ZFS status checking, a scrub every 7 days, and smartctl checking (requires the smartmontools package to be installed and `sysrc smartd_enable=YES`):
# 404.status-zfs daily_status_zfs_enable="YES" # Check ZFS daily_status_zfs_zpool_list_enable="YES" # List ZFS pools # 800.scrub-zfs daily_scrub_zfs_enable="YES" daily_scrub_zfs_pools="" # empty string selects all pools daily_scrub_zfs_default_threshold="7" # days between scrubs # 900 Smart status daily_status_smart_devices="/dev/ada0 /dev/ada1 /dev/ada2"
/etc/aliases was changed to point mails that would otherwise go to root to my personal email.
DMA from DragonflyBSD was installed to handle forwarding these status messages to my personal email from this machine (which is behind NAT on a residential network and therefore can't send its own emails). It was configured as follows:
SMARTHOST mail.paritybit.ca PORT 465 AUTHPATH /usr/local/etc/dma/auth.conf SECURETRANSFER MAILNAME mail.paritybit.ca MASQUERADE no-reply@paritybit.ca
With the following in the auth.conf file:
no-reply|mail.paritybit.ca:SUPERSECUREPASSWORD
A Samba file server is used to distribute files. First, the latest samba package was installed, then the following configuration was placed in /usr/local/etc/smb4.conf:
[global]
workgroup = NASGROUP
realm = nasgroup.local
netbios name = NAS
[nas]
path = /var/nas
public = no
writable = yes
printable = no
guest ok = no
valid users = jbauer
This was followed by:
sysrc samba_server_enable=YES system samba_server start
A system user with the same name as listed in "valid users" was created, and then `pdbedit -a -u jbauer` was used to enable the user for Samba.
Some tuning for performance was done. The following settings were set in /etc/sysctl.conf:
kern.maxfiles=25600 kern.maxfilesperproc=16384 kern.inet.tcp.sendspace=65536 kern.inet.tcp.recvspace=65536
And the following settings were configured for the zfs pool:
zfs set relatime=on nas zfs set compression=lz4 nas zfs set recordsize=1M nas
