I don't see the "mail" option when I start a pre-clear?  I see it as an option in video... but not in my options?

 

I get the mail notifications for other stuff like array health and what not..

If you're using Joe L. version, you don't. The reason is that the "mail" command used before unRAID 6 could interfere with the built-in Notification system. I've adapted the new system into preclear_disk and submit it here, but there's no response from Joe L.

 

In the mean time, you can use bjp999 version of the script that's stored on my github:

 

 

There's a version hosted here: http://bit.ly/1G44UhZ . This version have fast post-read and notifications enabled.

 

You can add this with this command:

wget http://bit.ly/1G44UhZ -O /boot/config/plugins/preclear.disk/preclear_disk.sh

 

readvz is already downloaded by the plugin.

Ok..  I think it's running now.  Thanks!

 

FYI....  I get this error when running the script..

 

/boot/config/plugins/preclear.disk/preclear_disk.sh  -M 4 -o 2 -c 1 -f -J /dev/sdl
root@Tower:/usr/local/emhttp# /boot/config/plugins/preclear.disk/preclear_disk.sh  -M 4 -o 2 -c 1 -f -J /dev/sdl
/boot/config/plugins/preclear.disk/preclear_disk.sh: line 635: [: missing `]'

 

The program is running..  but I got this error when it started.

Is there a fix for this small problem

I am using Chrome as my browser

I have a difficult time getting the Plugin to run after it starts

It takes 10 or 20 or more clicks of the Start button to start the plugin and just as many to the X button to stop the plugin.

I"m running chrome and it works just fine for me?

I couldn't replicate this behaviour, using Chrome/FF/IE/Edge. Maybe you have an extension that is messing with the code anyhow.

 

By the way, a 5 second interval before the status window opens is normal.

I uninstalled Preclear plugin and reinstalled using PLG link from first page, then uploaded the preclear_disk.sh you referenced in quoted text. Now it is offering to Preclear members of my array & cache disk? Something is not right.

PS. Thought maybe it was a Areca issue but in fact these are all the drives connected to my motherboard.  See screenie. Shaded serial numbers are on the Areca.

Have you started the array?  If not that might explain what you see.

 

Array is running. I even woke up all disks to see if that had an effect. Its only drives on the motherboard.

Are you using the 2015.09.28 version? If so, I just messed with some detection code, so it's possible that it broke something. I'll revert it soon.

Thanks.. I just loaded this on my unRAID1a setup. It seems to be working fine so far. I picked up six of the Seagate 3TB drives for $75 each from Newegg last week. In the past I typically just loaded my drives without testing them and didn't have any problems. But it seems like the drives today are less reliable than in the past. So I wanted to start using the pre-clear script. And this plugin certainly makes things much easier. Thanks!

I've also installed this on my unRAID2 setup. I've finished pre-clearing three drives in both systems and everything seems to have worked great.

I LOVE this plugin!  Thanks for the fantastic Work

 

Similar to the preview status... any chance a Smart Attributes snapshot icon/popup can be added?

The script seems to be removing some linefeeds from the  analyze_for_errors output and the cats of the smart reports..  It didn't do that before.

Any thoughts to why?  It would  be nice if this was more readable...

 

But great job, otherwise, on this plugin!  It's nice to have a gui for it!  I always had to look back and see what command line parameters I used in the past for any new pre-clears

You might need some quotes around the echo statement in the send_mail subroutine.

# gfjardim - add notification system capability without breaking legacy mail.

send_mail() {

  subject=$(echo ${1} | tr "'" '`' )

  description=$(echo ${2} | tr "'" '`' )

  message=$(echo ${3} | tr "'" '`' )

  recipient=${4}

  if [ -f "$notify_script" ]; then

    $notify_script -e "Preclear ${model} ${serial}" -s """${subject}""" -d """${description}""" -m """${message}""" -i "normal ${notify_channels}"

  else

    echo -e "${message}" | mail -s "${subject}" "${recipient}"

  fi

}

 

Changed to:

# gfjardim - add notification system capability without breaking legacy mail.

send_mail() {

  subject=$(echo ${1} | tr "'" '`' )

  description=$(echo ${2} | tr "'" '`' )

  message=$(echo "${3}" | tr "'" '`' )

  recipient=${4}

  if [ -f "$notify_script" ]; then

    $notify_script -e "Preclear ${model} ${serial}" -s """${subject}""" -d """${description}""" -m """${message}""" -i "normal ${notify_channels}"

  else

    echo -e "${message}" | mail -s "${subject}" "${recipient}"

  fi

}

Someone else can probably explain why it's needed for the cat output and not for the "\n" inserted into the variable!

 

but if I do this:

my_message="`cat /tmp/smart_start_sdl` \n";m2=$(echo ${my_message} | tr "'" '`' ) ; echo "$m2"

Now I haven't tried this in the script.  If I had a small disk to try this on I would..  I got rid of all mine.

I've now precleared seven drives(six Seagate 3TB and one WD 3TB) with this Preclear Plugin with two unRAID setups. It worked great with all of them.

So when does this drop the [beta] tag?  ;D

+1

 

All the other plugins on the forum are just WIP too.

Is there a fix for this small problem

I am using Chrome as my browser

I have a difficult time getting the Plugin to run after it starts

It takes 10 or 20 or more clicks of the Start button to start the plugin and just as many to the X button to stop the plugin.

 

I see this same behavior as well, regardless of which browser I use.  However, it might be related to the array disks being spun down.  If the majority of the disks in my system are spun down, it's sometimes impossible to get the preclear plugin popup to appear.  If the disks are spun up, then it's usually only one or two clicks to get the popup.

Question: If you are maxed out on drives (according to your unraid license) but you have SATA Ports available, can you still preclear a drive to test/check it? I guess I am asking if preclear is considered to be doing something to a volume outside the array?

If you have an available sata port, yes you can pre-clear the drive.  Pre-clearing happens outside the array

Depends.    If you're running v5, there's no limit on how many physical devices can be attached to the system.  If you're running v6, the license limits the number of physical devices you can have in the system UNLESS you have a Pro license.
