Humm this is a great guide but a lot of mistakes are made...

First LND is far very very far from being intensive for SSD the problem is people buy the WRONG SSD you need entreprise DRAM SSD like this Samsung PM883. You won't fried this SSD in a life time running LND... I have barely took 1% of mine in 4 years and it was second hand... DRAM SSD is where it's at!

Also ZFS is way superior than EXT particularly if you are going to move SSD. Exporting ZFS Pool is perfect and so easy to do!

A ZFS raid 1 system will be 100 time superior to a ext 4... There is no argument to that... One SSD fire the other one still kick change the SSD and you pretty much done no down time either! Run Proxmox and ZFS you will be sorted...

For routing I agree to disagree I used to never route I changed my fee to 1 sats and I run now over 25 M per day my node capacity is 0.25BTC outbound and my total capacity is 0.85 which is well over 280% and my node rips. I make like 1700 sats per week but re balancing happens naturally

Stop trying to make money you won't just have fun and learn I do not pay my electricity bills I spend a lot of sat but I'm having fun at the end of the day I may lose like what 30k sats per year in looping etc... What's 40 bucks per year to have fun and learn and connect to awesome peoples. None

Thank for the guide
