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.

Any thoughts on what could be wrong?
April 20, 20242 yr @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.

April 20, 20242 yr 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.

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.

April 23, 20242 yr 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, 20242 yr by Rozella Added line to error message
April 23, 20242 yr 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"
April 23, 20242 yr Author Update the plugin and reboot to clear up the tmux issue. Uninstalling and re-installing the plugin will not work.

April 23, 20242 yr Author 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.
April 25, 20242 yr On 4/23/2024 at 6:40 PM, dlandon said: Update UD Preclear and see if it solves your issue. Same. 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.

April 30, 20242 yr I've got a similar problem. I'm trying to preclear an EXOS 20TB drive. First one failed after somewhere between 1 and 6 hours. Less than 25% of the way through. So I'm on the next new 20TB drive. Fails in less than an 20 minutes. It tells me to go to UD and clear the drive. UD has had the dancing vertical lines for the past hour. I've cleared drives before. Never had this kind of problem. Now this drive is 2TB larger than my 2 parity drives. ( I have a 12TB failed drive ) I"M NOT GOING TO SLAP THIS INTO A PARITY SLOT WITHOUT A PRECLEAR.

May 1, 20242 yr OK Here is my latest diagnostics. Right now preclear IS running on the second drive (75%). But things are different. Compared to 2 months ago. Then everything was very transparent as to what was going on. Now it is not. The current status is hidden and is only available by bringing up the log. That WAS NOT the case 2 months ago. enigma-diagnostics-20240501-0956.zip

May 1, 20242 yr Latest update. New disk 2 has failed at something over 75% @ 18:42:45 Quote I don't see any drives that are not assigned to the array - i.e. thare aren't any unassigned disks. How are you doing a preclear on a disk? Disk 3 failed (12TB) and is being emulated. It has been physically removed. New 20TB drive was physically added to the array. It appears on the preclear page and has the option to preclear. Preclear initiated here. On this second drive I skipped the pre and post reads. Quote The status shows on the UD device: Status did NOT show on the main page under UD. There I had the dancing logo. Quote or on the preclear page: After the preclear started, I had no information unless I used the eye icon. Quote also on the footer: The footer on the main page rarely appeared. But when it did I could find info there. Quote You can also click on the eye icon and you can see the status. What do you think is missing? It seems that I had more information as to the progress of the process while it was ongoing. Just looked at the syslog. It looks like the sean of a crime. I think I may need an ambulance. Can you help? IS IT ANOTHER BAD DRIVE OR NOT ? Thank you. enigma-diagnostics-20240501-1433.zip
