Romove any instances of this text "root=sda" you see, save it, and then reboot. You should be able to preclear without memory issues. OMG ! You are a life saver. All working now Thanks soo much.

From the first post in this thread- Quote You can follow the status of preclears in UD, on the UD Preclear page, or by hovering your mouse on the preclear icon in the Unraid footer. There is also the option available to use the notification options configured in unRAID to send you notifications at intervals which you configure if you enable the notifications option in the preclear popup window. I usually prefer to receive an email at the end of every step and cycle. Quote Link to comment

I ended up letting it sit for over an hour to see if I'd get anything and below is all that showed up in the logs. Apr 3 18:24:55 Preclear script invoked as: /usr/local/emhttp/plugins/unassigned.devices.preclear/scripts/preclear_disk.sh --cycles 1 --no-prompt /dev/sdm Apr 3 19:33:46 Preclear stopped on all devices Apr 3 19:33:53 Preclear stopped on device: WD-CA3BXN1K It doesn't look to me like it did anything. Any thoughts on what could be wrong? Quote Link to comment
Hogwind Posted April 20 Share Posted April 20 (edited) @dionmunk Was it a broken UI stats or did you solve you problem? 👆 I'm having the same problem right now, can't see any status. Just stuck on "Starting...". Have checked with another browser and it looks the same. I'm just gonna let it be for a day or two. I have set the notification on 25% progress so maybe I get notifications. Edited April 20 by Hogwind Quote Link to comment

Gico Posted April 20 Share Posted April 20 Yes always stops somewhere after 22000000000000. Disk is attached to an onboard controller and the MB (Supermicro H12SSL-i ) has another one that seems to be identical. I will try with an HBA card. Quote Link to comment

At the end of a disk, the write takes longer and the dd write may time out too soon on a very large disk. I've already extended the time out, but it might need to be even longer. 1 Quote Link to comment

Rozella Posted April 23 Share Posted April 23 (edited) Tmux is no longer working since updating UD Preclear to 2024.04.23 – it produces the following error: tmux: /lib64/libm.so.6: version `GLIBC_2.38' not found (required by tmux) tmux: /lib64/libc.so.6: version `GLIBC_2.38' not found (required by tmux) Running the command /lib64/libc.so.6 shows that version 2.37 is installed, which is obviously a version behind the version mentioned in the error. I'm on version 6.12.8 of Unraid. Edited April 23 by Rozella Added line to error message Quote Link to comment
Gico Posted April 23 Share Posted April 23 After upgrading UD Preclear to 2024.04.23 when starting a preclear it offers to resume or start new one, and what ever I select it goes to "starting" mode and stays in that mode. Uninstalled and reinstalled the plugin and it's the same. Unraid 6.12.6. While installing I got the following message, which corresponds with @Rozella's post. "Checking tmux operation... tmux is not working properly" Quote Link to comment
dlandon Posted April 23 Author Share Posted April 23 I'm working on a fix and will update the plugin shortly. Quote Link to comment
dlandon Posted April 23 Author Share Posted April 23 Update the plugin and reboot to clear up the tmux issue. Uninstalling and re-installing the plugin will not work. Quote Link to comment

dlandon Posted April 23 Author Share Posted April 23 I forgot that different versions of tmux require different versions of libc. The version of libc in Unraid varies by Unraid version, so I have to do a version check to see which version of tmux can be installed for the version of Unraid running. I can't update libc, because it will break Unraid. It was an easy fix once I remembered what I needed to do. Quote Link to comment

First time it happens below byte 22000000000000. So if I put the disk in the array as parity, can this be ok? Maybe it's related only to the plugin's zeroing process? Alternatively if the disk is no good, I'll still will get an error, and then I guess I'll replace it.
