I find what you’re saying confusing…
Were you really using an rpi2 and the problem was happening on this device?
Is this rpi 4 that you’re now mentioning another device with a new installation?
Well, I’ve superficially reviewed the logs and something caught my attention. I’ll explain it to you with a comparison.
The following is from the log of one of my nodes: RPI 4, 2TB disk… well, like the one you say you have now.

If you look, it shows me the product name, manufacturer and disk capacity: [sda] 3907029168 512-byte logical blocks: (2.00 TB/1.82 TiB).
Ahora, veamos el tuyo.

Your log detects 2 disks. Both with the same manufacturer, different serial numbers and only detects the capacity of one of them: 1953525168 512-byte logical blocks: (1.00 TB/932 GiB).
Since you had told me…
I am using a Pi2, 2Tb drive and which logs should I attach, and how much?
Is your disk partitioned?..
To check this, connect via SSH to your rpi and run the command:
df
Then paste the result here, please.
