Notification of severe failures like ZFS degraded pools?

hotzen · Mar 24, 2011

How do you check whether your zpools are still fine?
SSHing every other day is not an option for me, I want at least an email and better yet: I want to get killed by that tiny but loud piezo-speaker of the mainboard

How do you accomplish notifications of zfs-failures, or more general of any severe server-failures? Im particulary interested in solaris-solutions but FreeBSD-specific solutions are just fine as a general advice.

Thanks

ChrisBenn · Mar 24, 2011

Gea's Napp It web interface automates this (allows you to setup email notification for drive failures. That's what I use.

I know of this solution but I hate perl-code and I want to extend it if needed, which forbids Perl as well as any other seemingly RSA-encrypted source...

Not all perl is unreadable. You might take a look at the source before writing it off.

hotzen · Mar 25, 2011

As I have tested napp-it, I actually had a look into the source.
ZFSGuru's PHP-Code is pretty straight forward but I dont feel like digging through napp-it.

So, if there is no nice solution yet, I will periodically check zpool status with a cronjob'd python-script..

I use a python and a sh script. I could probaby integrate them together, but I'm too lazy

#!/bin/sh

send=0

# Check zpool status
status=$( /sbin/zpool status -x )

if [ "${status}" != "all pools are healthy" ]; then
zpoolmsg="Problems with ZFS: ${status}"
send=1
fi

# Send status e-mail if needed
if [ "${send}" -eq 1 ]; then
/usr/local/bin/python ~/scripts/zfsmail.py
else
echo "0" > /home/olav/log/mailstatus
fi
exit 0

Awesome, that is what I am looking for. Thanks!

BTW, is there any easy way to *BEEP* the onboard piezo-speakers of the mainboard?

Sharing back an improved version of olavgg's script. It integrates both scripts into a single .py, also does disk SMART health checking (assuming you've compiled smartmontools) and sends email over SSL + authentication.

Code:

# Import smtplib for the actual sending function
import os
import sys
import smtplib
import mimetypes
from email.Encoders import encode_base64
from email.MIMEBase import MIMEBase
from email.MIMEMultipart import MIMEMultipart
from email.MIMEText import MIMEText

def sendAlertMail(subj, body):
	#print("sending mail...")
	FROM = '[email protected]'
	TO = '[email protected]'
	MAILSERVER = 'smtp.mail.com'
	PORT = 465
	MLOGIN = 'mylogin'
	MPASSWORD = 'mypassword'
	
	try:
		s = smtplib.SMTP_SSL(MAILSERVER, PORT)
		#s.set_debuglevel(1)
		s.login(MLOGIN, MPASSWORD)
		
		msg = MIMEMultipart()
		msg['From'] = FROM
		msg['To'] = TO
		msg['Subject'] = subj
		msg.attach(MIMEText(body))
		
		#send it
		s.sendmail(FROM, TO.split(";"), msg.as_string())
		#print("sending successful")
		s.quit()
		s.close()
	except Exception, e:
		print e
		sys.exit(1)
	
	sys.exit(0)

# uncomment the line below to test emailing
#sendAlertMail('ZFS NAS test', os.popen("/sbin/zpool status").read().strip())

# zpool checking
if os.popen("/sbin/zpool status -x").read().strip() != "all pools are healthy":
        sendAlertMail("ZFS NAS alert: zpool error", os.popen("/sbin/zpool status").read().strip())

# SMART checking
# include disks to be checked in the list
disks = ['/dev/rdsk/c3t2d0', '/dev/rdsk/c3t3d0', '/dev/rdsk/c3t4d0']
for disk in disks:
        s = os.popen('/usr/local/sbin/smartctl -a -d scsi ' + disk + ' | grep "SMART Health Status"').read().strip()
        if s != "SMART Health Status: OK":
                sendAlertMail("ZFS NAS alert: SMART error", os.popen('/usr/local/sbin/smartctl -a -d scsi ' + disk).read().strip())

sys.exit(0)

The script has to be run as root because of smartctl. I run it on an hourly cronjob. Edit as required

Are you running this in SMF?

No, just as a cronjob like the original author.
Since this script is no service/daemon, I dont know whether it suits the SMF...

Have you looked at the Nagios plugins?
http://exchange.nagios.org/director...Check-ZFS-file-systems-and-data-pools/details

hotzen · Oct 10, 2011

Seems a bit overkill, isn't it?
Will look into nagios as soon as I can virtualize it, thank you.

That script can be run independently of Nagios.

It would also be a good script to look at and see their approach, how they checked for X.

Just came into my head so I thought I would throw it out there.

hotzen · Oct 10, 2011

Thank you, that script is way more 'correct'.
However I just want a nightly mail with the rough status.

I use the more tailored ZFS-commands in https://github.com/hotzen/SolarStatus

Hi All,

I have installed multiple server with OmniOS and use the same python script as what is recommended here.

Now on a new server, when I run the python script, I got the following error:
[Errno 8] node name or service name not known

I run the python script with -d -v and this is the output:

If so, cant you just use svccfg ?

svccfg setnotify problem-diagnosed mailto:[email protected]

No need for PERL or such, it will send you a fancy report with the problem details and any corrective action it attempted.

A mini-script that calls a zpool status for a non online state is not the problem -
but hard to find mailers nowadays that accept non TLS emails.

That is the real problem - not Perl or any scripting language
(while I prefer Perl as it is there, always)

Notification of severe failures like ZFS degraded pools?
