Adding second harddrive howto. for squid
-
Adding second hard drive to PFSense v1.2.2, very very quick howto.
Purpose to doing this, is that squid can cache files to it's own drive.
I have now two 20Gb ide-drives in my system.First power off (of course) and install second drive to computer. You shoud
check that jumpers are ok on both drives, and ide cables are right. Computer bios must identify both drives ok, before continue.Power on computer. Connect to the PFSense from console.
This is the hardest and trickiest part:
Now you must format and slice the new drive, using fdisk, and newfs.Good how-to is:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/disks-adding.html
or google how to take new harddisk to use in Freebsd.Take the copy of original fstab file "cp /etc/fstab /etc/fstab.backup" in case that something goes wrong.
then edit the file /etc/fstab using vi.
quick usage: edit the file, press esc, and type "w!" +enter, now your changes are saved.Here is mine:
cat /etc/fstab
Device Mountpoint FStype Options Dump Pass#
/dev/ad0s1a / ufs rw 1 1
/dev/ad0s1b none swap sw 0 0
/dev/ad1a /cache ufs rw 1 1as you can see, I've added the last line to fstab, and I'm using just one slice (partition) ad1a. Now my cachedrive is /dev/ad1a and it is mounted to /cache
ad1a comes from atadrive (ad/ide) / slavedisk (1)/ slice a.
Masterdisk is ad0s?type:
#mount -awhen everything is doing right now, you should see:
df -h
Filesystem Size Used Avail Capacity Mounted on
/dev/ad0s1a 18G 732M 16G 4% /
devfs 1.0K 1.0K 0B 100% /dev
/dev/md0 3.6M 38K 3.3M 1% /var/run
/dev/ad1a 18G 3.6G 13G 21% /cache
devfs 1.0K 1.0K 0B 100% /var/dhcpd/dev…or whatever your disks are.
check
#ls /cacheNow, time to edit squid, go to webconfigurator, and go to squid tab. (services/proxy server/cache management) !!At this point you should have package "squid" added to PFSense.
Edit the line "Hard disk cache location" and type /cache
and "Hard disk cache size" to what ever you want, mine is 4000 (4Gb of 20Gb disk)
Also edit and modify other setting you like.Now you should have working squid cache in it's own drive.
You must also delete /var/squid/cache/*
and restart squid to take effect new configuration.
I'm sure I missing something here...but these instructions mainly are, how I got working second drive.You can monitor your cache size with command
#du -h /cache
or
#df -hps. I wish that somebody make ataidle and smartd packages to PFSense.
-
for some kind of fail over or improper shutdown other drive need to be scanned and mount.
If cache0 is the cache_dir /cache0
you need to edit also the squid.sh#!/bin/sh # This file was automatically generated # by the pfSense service handler. rc_start() { if [ -z "`ps auxw | grep "[s]quid -D"|awk '{print $2}'`" ];then if [ ! -d "/cache0/00" ];then if [ -z "`ps auxw | grep "fsck_ufs -y /cache0"`" ];then fsck -y /cache0 fi mount -a fi /usr/local/sbin/squid -D fi } rc_stop() { /usr/local/sbin/squid -k shutdown # Just to be sure... sleep 5 killall -9 squid 2>/dev/null killall pinger 2>/dev/null } case $1 in start) rc_start ;; stop) rc_stop ;; restart) rc_stop rc_start ;; esac
