The status seems to be updating correctly now. Although it has started the post read from the beginning. Oh well.

 

Thanks so much for your help.

 

Kind regards,

Neil

 

 

 

Looking at your logs it got stuck in the beginning of the post read, so resuming from the beginning is the correct behavior.

What would anticipate the speeds to be on a USB enclosure for preread? It is USB 3 but only getting like 35MB/sec. I think it’s on a hub though, may be the issue.

You're quite welcome!

Had a preclear failure yesterday.  Using standard script.  It stopped (apparently) at the beginning of the Post-read.  The Preclear Status condition was "unRAID's signature on the MBR is valid".  It has been 'stuck' at this state for more than eight hours and probably closer to twelve hours

 

 I have attached all of the pertinent information in the attached files.  The Preclear_Failure.txt file is the current state of the Status Window.

 

EDIT:  I did preclear a Seagate ST3000DM001_1CH166  disk (one of the infamous series) a couple of days ago without a problem.

No need to do that. Just stop the preclear, update the plugin and start it again.

I decided to try this and it picked up from where it left off.  It has now completed 1% of the Post Read.  I will report back if/when it finishes.

The restart of the Preclear did resume and complete successfully.  I am attaching the Preclear zip file and the Diagnostic file that I captured after the test finished to this report for your analysis.  Do you have any thoughts as to why the preclear process hung up?  

 

I feel I must point out that I did not upgrade the Preclear software after the hang occurred as it was already on version 2018.08.27. So the hang did take place with this latest version.  I will also point out that the Seagate ST3000DM001 did preclear successfully a day before The WD Red had issues using this version of the software.

 

If you want me to run any other tests, I am willing to do so.  But I do want to update this server to the ver 6.6-rc1 to see what is really new and great in that release but I will delay for a couple of days before I do it.

The recent update to the preclear plugin seems to have broken it for me.

 

I an trying to "erase and clear" 6 disks. Only one of the disks is actually doing something, the others are stuck with message "Starting...".

 

Thoughts?

Try stopping (red   X  ) and restarting.  That worked for me...

I tried that, and having now done it again, they are clearing. However, the 1st disk is clearing at 143MB/s, the other 5 preclear processes are around 10MB/s.

Previously, they all ran at full speed.

 

@gfjardim  Preclear has failed multiple times on zeroing.  Seems to always hang at 99%.  I stop and resume (starts at 0%) and it will hang again.

Have you tried just using JoeL's script (or one of the others) from the command line?

Another option would be the disk testing utilities provided by the various manufacturers since the "preclearing" is no longer really necessary.

I have an issue with preclear my WD Red 3TB hdd. When I ran this plugin with my other HDDs that worked excellent, but for some reason this drive is stuck on "Starting...". I have tried to restart it and leave it for a few hours, but it's still stuck on "Starting...". I have attached my preclear log.

I realize that you are very frustrated but if you really want to help solve the problem(s), you are going to have to provide some more information that might help in solving it.  Specifically, your unRAID Diagnostic file and the preclear log file.  You will find the download button for the latter on the top right of the Preclear plugin page.

Thx for the reply. The preclearfile was linked in the post before, syslog attached now.

That sounds like a good alternative.  What exactly would that look like? /flash/config/plugins/preclear.disk/preclear_bjp.sh? Asking for a friend.....

Yes. Run it with screen so that it will continue after you exit.

 

Edit: Actually it's /boot/config/plugins/preclear.disk/preclear_bjp.sh

Does anyone know what the issue can be? Shall I test and install an older version of the plugin and see if that helps? If so, how do I do that?

Here is my diagnostics data.

It seams that doesn't  on my system. Did I miss something?

Look in the first post of this thread at the first and third questions in the Q&A section for the location of the script for downloading.  If you are wondering why the scripts are not installed with the plugin, read that first post very carefully...  (like a lawyer)

Also, if you're going to run the script from terminal via screen, any location on the flash will work as long as you know what it is. I just use a "scripts" folder at the root of the flash drive.

Yes. Run it with screen so that it will continue after you exit.

Don’t you have to put sda or something on there to tell it what drive. I’ve seen scripts with what look like switches as well -f I think.
