One thing I'm considering is whether to disable the notification email. FreeNAS will notify you anyway if you have email set up (and if you don't, you won't get the email from this script either), so it seems kind of redundant.

I agree, you wouldn't want two emails about a drive failure.

Great work.

Thanks

danb35 submitted a new resource:

Disk failure LEDs for Supermicro SAS backplanes - Script to light up disk failure LEDs when disks fail

Many hot-swap backplanes have disk-failure LEDs that can be turned on when a disk fails. Unfortunately, there doesn't seem to be a standard mechanism to do this, and FreeNAS doesn't have any built-in support for this feature.

Using inspiration from a couple of other sources (and by inspiration, I mean I blatantly ripped off, and tweaked to work with FreeNAS), I've modified a script that will light up the disk-failure LEDs on, at least, Supermicro SAS2 expander backplanes. I don't have any...

Ok! A cron job with the mirror version works ok!

If I try it with a raidz2 the cron errors with the following
Code:
 rm: glabel-lookup.sed: No such file or directory

Curious--it seems to run without issue on my RAIDZ2 pool. What happens if you replace every instance in the script of glabel-lookup.sed with /tmp/glabel-lookup.sed? There should be six places to make this change.

I created another file and renamed zpscanz.sh ran it as cron job and it first failed with
Code:
/usr/local/bin/zpscanz.sh: line 26: [: missing `]' 

then I added a space in the offending line after "YES", ran the cron job again and it emails me but fails to locate the disk. If I run it in the shell it runs fine.

But... Here is why is not marking the disk
Code:
Sending email notification of degraded pool tank
Locating failed drives.
Locating: da2 5003048-0-006f-72ad

here is the result of a zpool status if it helps somehow:

Hello Dan!
Updated the script with latest version, it runs flwaslesly in the shell and cron job with my mirror pool, but with my raidz2 pool as a cron job fails with:
Code:
rm: /tmp/glabel-lookup.sed: No such file or directory


here is some additional info:
the script is in /mnt/tank/scripts/
I applied the chmod +x zpscan.sh to the script inside that folder
in the cron job details, user as root, command bash /mnt/tank/scripts/zpscan.sh tank

the script runs works with the raidz2 pool in the shell, don't understand whats going on :(

Shouldn't make a difference, but try taking "bash" out of that command--the script should run on its own.

Does it run from the shell with just the script name/path? /path/to/zpscan.sh poolname?

Yes!
Code:
[root@m5_nas ~]# /mnt/tank/scripts/zpscan.sh little_tank						
Saving drive list.															 
[root@m5_nas ~]# /mnt/tank/scripts/zpscan.sh tank							   
Saving drive list.															 
[root@m5_nas ~]#


do the tmp dir needs to be created before hand?

What happens when you try to run them from cron?
by disabling Redirect Stdout in the cron job details, here are each of the results received by email

mirror pool email subject:
Code:
Cron <root@m5_nas> PATH="/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:/root/bin" /mnt/tank/scripts/zpscan.sh little_tank

email contents:
Code:
Saving drive list.


raidz2 pool email subject:
Code:
Cron <root@m5_nas> PATH="/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:/root/bin" /mnt/tank/scripts/zpscan.sh tank

email contents:
Code:
Saving drive list.
rm: /tmp/glabel-lookup.sed: No such file or directory


it seems that the mirror pool is working now, but I had recieved before a:
mirror pool email subject:
Code:
Cron <root@m5_nas> PATH="/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:/root/bin" /mnt/tank/scripts/zpscan.sh little_tank > /dev/null

email contents:
Code:
rm: /tmp/glabel-lookup.sed: No such file or directory
