My original #Bitcoin Core node (from Nov 2019!) finally maxed out its 500GB ssd a few days ago.

Bought a 1TB and cloned the old drive.

Quick 🧵 on how to swap your SSD:

I use @SpecterWallet so first I backed up my Specter data and Bitcoin Core's wallets dir using `scp` from my Macbook. `scp` uses the same login credentials as ssh.

(obv your directories on your Pi will vary)

Opted for this SK hynix 1TB ssd.

* I powered down my node (Pi1)
* Moved its 500GB ssd to a different, already running Pi (Pi2)
* Also plugged the new SSD into Pi2

* On Pi2 I ran `lsblk` to list the drives. In my case the old 500GB ssd was "sda" and the new 1TB ssd was "sdb".

(screenshot is from a diff setup, but you get the idea. Easy to identify which ssd is which by the SIZE col)

* Cloned the old ssd to the new one with `dd`:

sudo dd if=/dev/sda of=/dev/sdb status=progress bs=64K

`if` is the input (source) drive. `of` is the output (destination) drive.

Will take a while to copy 500GB. Go have lunch.

* Unplugged the 1TB ssd from Pi2 and plugged it into Pi1 for the first time.
* (crosses fingers)
* Once it booted I `ssh`ed in and ran:

sudo raspi-config

* Advanced Options > Expand Filesystem

This ensures that the OS uses the full capacity of the new ssd.

* Finish and reboot

* `ssh` back in and confirm capacity with `df -h`

Yeehaw! 439GB now available!
