Unfortunately they don't work in some situations, although I haven't tracked down the specifics yet. I have a 50GB minimum set on each share, yet I still have a few disks than continue to fill up past that without triggering warnings.

Disk utilization warnings are set in disk settings not share settings. From your post, if the share continues to fill with less than 50GB available you may have the split level set wrong.

Notifications for disk utilization won't do anything to keep you from filling a disk, it is just a notification. You need to fix whatever. Maybe start a new thread with your diagnostics.

Hey, is there also a script to backup the cache drive?

Netix · February 15, 2023

So I'm running the updated Shrink array that was posted in the last pages. I shrinked one 6TB drive that had error and it went well.

Now, I'm trying to Shrink away another 8TB drive but I'm getting some really slow speed.. ~4 MB/s.. For the 6TB it was way faster then that. I'm wondering how to troubleshoot the low speed.. Any idea? Turbo write is activated.

Possibly you disturbed connections when you removed the other drive.

Had an unsafe shutdown, had to run a parity check and just restarted the script. It still run at 1.5 mb/s..

Here's my diagnostics while the script is running

Run an extended SMART self-test on disk11.

Looks like disk11 is unmountable, so maybe that is the one you are clearing.

If so, you could just New Config to remove it and rebuild parity.

Hi Squid

Does this script still work in 6.11.5 , 5 years later after this post?
I'm trying to use it to trigger a basic script to backup my server and power-off but i just get errros when running it.
If ti does still work, can i get an example of the correct syntax for an example of "full path the script" please?

Thanks kindly.

Hey there.

It passed the extended SMART self-test. Retried the script, still going at 1.5 mb/s.. what are my options ? I would really like to remove that drive without going 0 parity..

Allows you to set the threshold of utilization on the source to trigger the move

Moves are selectable to either completely move the source or to stop after the threshold has been reached

Move either the oldest folders or the newest folders first

Option to pause during a parity check / rebuild

Option to skip if the folder to be moved already exists in the destination or to delete it and copy

Option to skip or abort if an error happens during the copy

Option to run a custom script (ie: notifications) upon completion.

This is really usefully script.

I'm wondering if there is any chance to add an option to move the folder only if the files inside (inc subfolders are NOT hard linked.

Basically, to move unique files only, as moving hardlinks in between the drives makes a copy of the file.

In result even more space is taken.

I'm using this to find not hardlinked media files

find /mnt/user/data/media* -type f -not -path "*/Scenes/*" -not -path "*/Behind The Scenes/*" -not -path "*/Trailers/*" -not -path "*/Featurettes/*" -not -path "*/Other/*" \( -iname \*.mp4 -o -iname \*.mkv ! -iname "*gag*" ! -iname "*sample*" ! -iname "*blooper*" ! -iname "*Outtake*" \) -links 1 -print | sort

Clear an unRAID array data drive (for the Shrink array wiki page)

This script is for use in clearing a drive that you want to remove from the array, while maintaining parity protection. I've added a set of instructions within the Shrink array wiki page for it. It is designed to be as safe as possible, and will not run unless specific conditions are met -

- The drive must be a data drive that is a part of an unRAID array

- It must be a good drive, mounted in the array, capable of every sector being zeroed (no bad sectors)

- The drive must be completely empty, no data at all left on it. This is tested for!

- The drive should have a single root folder named clear-me - exactly 8 characters, 7 lowercase and 1 hyphen. This is tested for!

Great script! Worked like a charm for me when I wanted to remove a disk to reformat it.

But I was wondering if it would be possible to write the same marker as preclearing a disk does at the end of the script? Because after I removed the disk I still had to preclear it (basically a second time) -- which was a total waste of X extra hours 😬

trurl · April 4, 2023

Sounds like you added the disk back after removing it. If all you were trying to accomplish was formatting the disk there was no reason to remove it from the array. And after you add it back you still have to format it in the array.

https://wiki.unraid.net/Manual/Storage_Management#Reformatting_a_drive

nico_francois · April 4, 2023

Ah, excellent. And I take it this will not force a full parity sync afterwards then?

But do I even need to run the clear-me script at all then? 🤔

war4peace · April 21, 2023

I am trying to use the script to zero out Disck #6 from my array.
Followed all instructions, emptied the drive using Unbalance, drive is now empty.
I created a folder called 'clear-me', exactly as specified.

Running the script yields the following:

root@Tower:/boot/config/cleardrive# sh clear_array_drive 
*** Clear an unRAID array data drive ***  v1.4

Checked 6 drives, did not find an empty drive ready and marked for clearing!

To use this script, the drive must be completely empty first, no files
or folders left on it.  Then a single folder should be created on it
with the name 'clear-me', exactly 8 characters, 7 lowercase and 1 hyphen.
This script is only for clearing unRAID data drives, in preparation for
removing them from the array.  It does not add a Preclear signature.

Could it be the way I created the folder?

I used this command from Terminal:

cd /mnt/disk6/

mkdir clear-me

The disk is empty and freshly formatted, with just that folder on it.

root@Tower:/boot/config/cleardrive# du /mnt/disk6
0       /mnt/disk6/clear-me
16      /mnt/disk6

Any idea why the script dislikes the disk/folder?

Script to recover corrupt Radarr or Sonarr databases

Recently my radarr and sonarr logs have been showing:

So if anyone else bumps into problem with this script, on line 24 there is a / missing, and the script will give you errors for that.

So add / infront of var/local/emhttp/var.ini on line 24.

If you get permission errors like i did, add "bash" to the pathway of the running and stopping script, like "bash /path/to/script/"

While preparing to shrink my array, I had a question which I didn't see documented on the wiki or in @RobJ's zeroing script post. If we are zeroing the data disk, shouldn't we disable the mover? Otherwise, don't we run the risk of data loss if the mover runs and moves data to the disk being zeroed?

I doubt if that is a problem as the zeroing process is going to almost immediately destroy the file system on the drive so it would not be possible to write file to the drive. I have not checked but I would expect the script to also have unmounted the drive before it started zeroing it.

You're right:

# Perform the clearing
logger -tclear_array_drive "Clear an unRAID array data drive  v$version"
echo -e "\rUnmounting Disk ${d:9} ..."
logger -tclear_array_drive "Unmounting Disk ${d:9}  (command: umount $d ) ..."

i don't undestand where is the difference from 796k to 18836 K...

The script trims the Docker logs in the "/var/lib/docker/containers" directory.

The script doesn't trim any log files in the "/var/log" directory.

You could easily adapt the script to trim the logs in the "/var/log" directory.

I am not sure why you are seeing different usage numbers.

Sorry, i didn't put my script

size=100k

function trimLog
{
	file=$1
	temp="$file.$(date +%s%N).tmp"
	time=$(date --rfc-3339='seconds')
	before=$(du -sh "$file" | cut -f1)
	echo -n "$time: $file: $before=>"

	tail --bytes=$size "$file" > "$temp"
	chown $(stat -c '%U' "$file"):$(stat -c '%G' "$file") "$temp"
	chmod $(stat -c "%a" "$file") "$temp"
	mv "$temp" "$file"

	after=$(du -sh "$file" | cut -f1)
	echo "$after"
}

find /var/log -maxdepth 5 -type f -size +$size 2>/dev/null | sort -f |\
while read file; do trimLog "$file"; done

find "/boot/logs" "/var/log" "/var/lib/docker/containers" -name "*.log" "*log" -size +$size 2>/dev/null | sort -f |\
while read file; do trimLog "$file"; done

Clear an unRAID array data drive (for the Shrink array wiki page)

This script is for use in clearing a drive that you want to remove from the array, while maintaining parity protection. I've added a set of instructions within the Shrink array wiki page for it. It is designed to be as safe as possible, and will not run unless specific conditions are met

Hello!

Thanks for the script. Can I ask for the advice, how should I know if the script completed successfully? I was trying to remove Disk4 from the array, and was preparing it as per https://wiki.unraid.net/Shrink_array Method 2.

I've left the tab with User's Script open over a night, but the web-client switched off during the night.

How can I understand was the process completed successfully or not?

If I should re-run it, would it work, if I run it with "Run in background", can the web-client be disconnected in that case? Initially I've run it with "Run Script" button, and failed to keep it open for such a long time.

So after my fiasco with Plex. at 1st thought was a major bug in plexpass, which then continued to plex docker. I had followed along with the video on fixing a corrupt plex database. It got me wondering if i could write out a userscript that could automatically guide a user though and fix a plex database. currently only works with @binhex plex containers for now but may expand to other plex docker containers. This is the userscript link https://gitlab.com/Goldmaster/plex-database-fixer/-/blob/main/plex-database-fixer.sh I did write this with the help of chatgpt. so may be some issues.
