mikela Posted June 14, 2022 Share Posted June 14, 2022 Success! Thank you for this wonderful plugin. Really great for those of us that need to shutdown our servers at night. 👍 Quote Link to comment
Brenton Spear Posted June 23, 2022 Share Posted June 23, 2022 (edited) This is a great plugin! I incorrectly added 6 drives to my array before I used Preclear. I have since removed them from the array and they are showing up in UNRAID as "Unassigned Devices". Two are currently running Preclear as I didnt make the same mistake with these ones! The drives don't have any data on them and will go into a MD1200 DAS server that i will install shortly. How do I 'reset' the drives so that they show up under Preclear?

Brenton Spear Posted June 23, 2022 Share Posted June 23, 2022 I worked it out! For anyone interested: 1. Make sure you have "Unassigned Devices Plus" plugin 2. Go into the settings of Unassigned Devices 3. Enable "Destructive Mode" 4. Click on the red X next to the drive serial to remove the partition Obvious now that I know Quote Link to comment
Reacher Posted June 27, 2022 Share Posted June 27, 2022 Hi! I have an existing Unraid server and am working on setting up a back up. I'm using used WD Yellow Enterprise drives and want to pre-clear them. However, when I go to install the UD Preclear Plugin I get the attached error calling out that Requirements Not Met. I originally thought that I needed to upgrade to the latest version of Unraid. I did this on my "backup" server and am still getting this error. Also getting it on my original machine running 6.9.2. Any help would be greatly appreciated. Thanks so much! Chris Quote Link to comment
dlandon Posted June 27, 2022 Author Share Posted June 27, 2022 Install the Unassigned Devices (UD) plugin first. The UD Preclear is an add on to the UD plugin. Quote Link to comment

dlandon Posted June 28, 2022 Author Share Posted June 28, 2022 Install UD+ if you need to manage partition removal and/or clearing of dsks. You can't preclear a disk if it has any partitions. Quote Link to comment
DarphBobo Posted June 28, 2022 Share Posted June 28, 2022 Just noticed that the avatar you use when you stare at it long enough stares back at you and it looks really pissed off. Maybe those old radios were originally in the Amityville Horror. @kizer would be impressed @dlandon Quote Link to comment
Reacher Posted June 29, 2022 Share Posted June 29, 2022 Hi! I precleared 4 WD Yellow 6 TB drives via this plugin. 2 Failed and 2 passed. Both of the failed drives pass SMART and failed on Post Read Verification. I've read around that it could be bad RAM, but since 2 of the 4 drives did not fail on that error I'm curious if it's something else. I also read that doing the preclear on one drive at a time can help. Any suggestions would be greatly appreciated! Screenshots of Output attached. Thanks! Chris Quote Link to comment

Non-trivial number of reallocated sectors or pending sectors I would not be happy with the drive. I would suggest trying the extended SMART test - if that cannot complete there is rarely any point in continuing with the drive. Quote Link to comment

In fact @dlandonIMHO you should remove that part from the summary, it will just confuse users, SMART assessment only fails if there's a "FAILING NOW" SMART attribute, and the GUI already warns about that.

jeffrey.el Posted July 2, 2022 Share Posted July 2, 2022 Hello! I just tried to pre-clear a drive, but it's stuck at starting for hours... does anyone have any idea what might cause this? I've cleared multiple drives in the past with this plugin, all successful. 1 Quote Link to comment
FQs19 Posted July 2, 2022 Share Posted July 2, 2022 Starting to recover from hardware and software errors after months of being down. I'm having issues with two of my NVME drives, they're both Sabrent Rocket 4.0 1TB drives. I couldn't mount the Sabrent Rocket NVMEs. After clicking on 'Mount', nothing happened. The drives also wouldn't let me delete the original partitions. After restarting, I still couldn't 'Mount' the drives, but was able to delete the partitions. The problem I'm having now is that when I go to Preclear the NVME drives, none of the drive's info is available. There is also no Disk Log information available, but I can see everything under the devices 'Identity'. Anyone have an idea of what is going on? My hardware is in my signature. threadripper19-smart-20220702-1606.zip threadripper19-diagnostics-20220702-1612.zip Quote Link to comment

I was able to get the drives to Preclear after I started the array, but the read/write performance is horrible. the max speed I’m getting is only 130MB/sec. Quote Link to comment
FQs19 Posted July 3, 2022 Share Posted July 3, 2022 Anyone have an idea why both of my Sabrent Rocket 4.0 NVME drives Precleared at such a ridiculously slow speed of 104 MB/S taking over 3hrs to preclear a 1 TB drive? They're PCIE 4.0 drives on a PCIE 4.0 capable motherboard. When I used unraid 6.9.2 and the previous preclear plugin from gfjardim, I was able to get over 3000 MB/S and it finished in minutes. Attached are my diagnostics and a screenshot of the Identity page. threadripper19-diagnostics-20220703-0923.zip Quote Link to comment
JorgeB Posted July 3, 2022 Share Posted July 3, 2022 Preclearing flash devices is not recommended, you'll just be causing unnecessary wear, as for the performance try a write test to see how they are performing, if speed is the same it's likely a device problem. 1 Quote Link to comment

Wasn't aware of that. Thanks. Would using the DiskSpeed docker be okay to use to test for speed or should I just configure the drives then transfer a file to the NVME from another pc? I don't feel like setting up an iPerf test. Quote Link to comment
JorgeB Posted July 3, 2022 Share Posted July 3, 2022 Diskspeed is read only test, best to just test form another PC, assuming you have 10GbE or better. 1 Quote Link to comment

You are using something that requires an additional slackware package - glibc. I suspect that dlopen was updated and now requires the glibc 2.34 package. I ran into this when I updated the tmux package in UD Preclear. It now requires glibc 2.34. Unraid 6.10 has glibc 2.33 installed which is a version behind. As a quick work around, install the latest version of the UD Preclear plugin that installs the glibc package updated to 2..35. Quote Link to comment
