Thanks, are these lines a matter? I found these on the detailed report

 

== Disk /dev/sdd has NOT been successfully precleared

== Postread detected un-expected non-zero bytes on disk==

i would assume some other process has written to the disk after the zeroing of the drive, you may find unraid wants to clear the drive again, but other than that its of no concern.

Is this still the way to preclear? seems awfully convoluted I was hoping it might just be a few gui clicks.

Preclears are no longer required to add the drive to your array. The UI will clear the drive for you. If you want to test a new drive by running a few cycles then this is probably the easiest way. It really is just a few clicks.

oh ok thanks. I was actually wanting to 'preclear' some 8 year old drives and see what happened because they may be dying I'm not sure, what else could I do to sort of stress them and see if they fail?

You’ll need to delete whatever partitions are on them using UD+ and then you should see a preclear icon. Once you select it you’ll get options for how many cycles and how often you want notifications.

Hi, I just noticed that the container size is 1.31GB, is this normal? And how can I remove the docker fully without affecting anything else?

simple - left click the container and select 'remove' make sure also remove image is ticked and then click on 'yes delete it'.

For anyone interested, the below is the minimum required to run this container using docker-compose, based off the example docker command from the repo. You can modify it easily to use traefik or another reverse proxy instead of accessing directly by port. Change $CONTDIR to wherever you want to store the logs.

 

  preclear:
    container_name: preclear
    image: ghcr.io/binhex/arch-preclear:latest
    restart: unless-stopped
    privileged: true
    ports:
      - 5900:5900
      - 6080:6080
    environment:
      - WEBPAGE_TITLE=Preclear
      - VNC_PASSWORD=mypassword
      - ENABLE_STARTUP_SCRIPTS=yes
      - UMASK=000
      - PUID=0
      - PGID=0
    volumes:
      - $CONTDIR/preclear/config:/config
      - /boot/config/disk.cfg:/unraid/config/disk.cfg:ro
      - /boot/config/super.dat:/unraid/config/super.dat:ro
      - /var/local/emhttp/disks.ini:/unraid/emhttp/disks.ini:ro
      - /usr/local/sbin/mdcmd:/unraid/mdcmd:ro
      - /dev/disk/by-id:/unraid/disk/by-id:ro
      - /boot/config/plugins/dynamix/dynamix.cfg:/unraid/config/plugins/dynamix/dynamix.cfg:ro

So I just went to check on my preclear and the VNC remote screen looks like attached. How do I know if it’s still running? It’s as if there’s a terminal window oversized on my screen but I can’t scroll to see any command line?

 

Edit: So I can see from main UnRAID screen the disk is still being written to as it was in the zeroing phase. I just can’t get the terminal window to show up?

 

Edit 2: So I managed to get the terminal window back but no idea what I did exactly. I was trying to set different scaling options to see if that would work but no change.  I pinched the screen (working on an iPad) and it was back. Prior I was using AnyDesk on my Windows vm to check progress. Perhaps the combination of pinching between the two caused it?? 

 

 

Well, 2.5 yrs later and I have the same issue...ugh. Will check the ipad to see if I can get it back there.
