It turns out that if I have a non-recommended NVME disk, for example, a 2TB pioneer, the system may not work stably? How can I, for example, rewrite the BTC database to a new NVME disk? Can I connect a new disk to the Apollo 2 node via a USB adapter and how can I rewrite the database?

As described earlier, you can copy the bitcoin database to a USB connected nvme drive interface. Takes under 1 hour these days on my Apollo II. Make sure your node is stopped and your miner is stopped. You all should do this every 2 to 4 weeks anyway so you have a bitcoin backup. any sort of power outage can corrupt the memory.

You could also purchase a nvme clone device that will copy the data NVME to NVME pretty fast.

The format command in apollo wipes the drive.

jstefanop has answered the question about what nvme 2TB is compatible with these systems. Hardware compatibility. These cards will be cheaper than the newer faster cards. read write speeds are only in the 100-200MB / sec range. USB 3.0 speed. This is a simple system designed for running a node and a miner. nothing fancy.

Look around the system monitor. Watch the activity of the bitcoind program and the node program and the ckpool program if mining. You can see read/write activity of the bitcoind being the most active.

Regarding the nvme running out of space, what does the system monitor say is left on the nvme? Do you get an error message? the system monitor will tell you space used vs space available. So you say at 80% complete, you have 0% nvme disk space remaining?
