Pfsense on a HP Netserver LPr

ugob · Jun 19, 2007, 4:27 PM

But does PfSense supports software RAID? I think a LiveCD + floppy is more reliable (at least for running) than a single disk. The only RAID controller I have here is an HP NetRAID 1-M. Will it work?

I just tested and it works with th HP NetRAID 1-M. I'll get 2 small SCSI disks and I'll use that.

Anyone knows how to monitor for failed drives this way? If it was on linux, I'd check /proc, but I don't know about freebsd.

Thanks!

Yes for Linux I know it too, but I will check it.

Were you able to monitor the controller for failing disks ?

@ugob:

I haven't checked really, but I think it sees only 1 CPU. I don't really care if it sees only one though.

No I don't care if it sees one, but I want to be sure it uses both.

This is what I see:

kern.smp.cpus: 1

So if it sees one extra CPU for SMP or at total one.

Mine sees and uses both.

In top, I can sometimes see process using CPU1 when I hold the spacebar.

From dmesg:```
FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs
cpu0 (BSP): APIC ID: 1
cpu1 (AP): APIC ID: 0

No, all I found is this:

amrstat is available as a package, but since my pfsense is not connected to the 'net right now, I can't try.

However, since there is no mta on pfsense, another system would have to run a script via ssh and send an e-mail if one drive is failing.

It would be easier using snmp.

Please let me know if you find anything.

I found something:

# pkg_add -r http://ftp.id.freebsd.org/ports/packages/All/amrstat-20070216.tbz
# rehash
# amrstat
Logical volume 0:       degraded (16.96 GB, RAID1)
Physical drive 0:0      rebuild
Physical drive 0:1      online

Now you can use a remote server to execute amrstat remotely via ssh and grep for 'degraded'. If grep returns 0, send an e-mail.

I have installed the AMRSTAT Port, but I can;t get it working.

FreeBSD is actually quite new for me :) If it was Linux.. it was more simple ;)

Look http://forum.pfsense.org/index.php/topic,5252.msg31671.html#msg31671

3 simple commands.

Hi,

I already installed it using this:

pkg_add -r amrstat

This is what I get because I already installed the latest version I thought

# pkg_add -r http://ftp.id.freebsd.org/ports/packages/All/amrstat-20070216.tbz
Fetching http://ftp.id.freebsd.org/ports/packages/All/amrstat-20070216.tbz... Done.
pkg_add: package 'amrstat-20070216' or its older version already installed
#

And I get this now:


# amrstat
open: No such file or directory
# where amrstat
/usr/local/sbin/amrstat
# /usr/local/sbin/amrstat
open: No such file or directory
# /usr/local/sbin/amrstat --help
amrstat: illegal option -- -

Maybe your RAID controller is not supported by this program. How are labeled your disks?

I will check it, I thought it was.

What do you mean by this ?

Give me the output of 'df'

/dev/idad0s1a 13133670 75896 12007082 1% /
devfs 1 1 0 100% /dev
/dev/md0 1710 26 1548 2% /var/run
devfs 1 1 0 100% /var/dhcpd/dev

Btw, I was thinking of using smartmontools. After installing this I see that libcam* is missing.

Or we have to get a full install tree, what not should be it.

Your RAID controller doesn't use the amr driver, so you can't use amrstat

If you get smartmontools, how will you get notified of a failed disk?

I think I found how to do it, using an Expect script. I haven't tried it yet 'cause I don't have the pfsense machine close, but I will as soon as I can boot it up.

Here is the script:

http://bash.cyberciti.biz/security/sshlogin.exp.php

This script is executed from a remote host, on which expect is installed. I'm just beginning with expect, so I hard-coded all my values in the script. I know this exposes the firewall root password in a file, but I think I can live with that until I find a better way to be alerted when a drive fails.

#! /bin/bash

RETVAL=0

/home/user/expect_amrstat > /home/user/expect_degraded

grep Degraded /home/user/expect_degraded >dev/null

RETVAL=$?
if [ "$RETVAL" = 0 ]; then
        echo "Array degraded on firewall"  |mail -s "Array Degraded" me@mydomain.com
fi

The script /home/user/expect_amrstat simply runs amrstat on the firewall and outputs the result.
