Installed grocy on a server and magic mirror on a pi. Now we can track all the daily tasks of life which makes my wife happy

Static, hand coded html. You can be as pretty as you want to be. A good learning exercise and since it is all static it will be fast and won’t have more security issues.

That means you haven’t make them large enough yet.

Good luck getting people to care, but it is in the end your best counter.

Long term boycottes are the best thing - IF you can get large numbers to follow. Large enough that management schools are forced to teach about how ever real reform won’t be enough to save you from bad actions.

ZFS even if only one server is much better than most people have. If your ZFS replication is to a different building you have done pretty good. However as others have pointed out there are limits. Those servers costs you a couple bucks/month in electric (where I live my electric is 100% wind, but most of you should read CO2). You have to buy both servers, and hard drives will crash regularly.

There are a lot of trade offs, but cold storage backups are often much cheaper in the long run than the backup zfs server. And those cold backups are a lot easier to put into multiple different locations.

It is a pain to figure out how to give everyone the same user id. I only have a couple computers at home. I’ve never figured out how to make LDAP work (including laptops which might not have network access when I’m on the road). Worse some systems start with userid 1000, some 1001. NFS is a real mess - but I use it because I haven’t found anything better for unix.

on life support thay haven’t pulled the plug yet but it is coming. They are not updating anything not urgent and so new hardware support is dead as are jails to do useful things. I’m probably moving to xigmanas in the near future.

I know, I like BSD. However because core isn’t a supported version of FreeBSD I cannot update the other things I run on my NAS. I’m more worried about an attack on those out of date services than I am about the few issues that have been fixed

only the most basic security. It is out of date according to the pkg system and so jails cannot be updated-

At least you get updates. I’m running TruNAS core which isn’t updated anymore, and I have some jails doing things so I can’t migrate to scale easially.

The good news is this still works despite no updates it does everything it used to. There is almost zero reason to update any working NAS if it is behind a firewall.

The bad news is those jails are doing useful things and because I’m out of date I can’t update what is in them. Some of those services have new versions that add new features that I really really want.

I have ordered (should arrive tomorrow) a N100 which I’m going to manually migrate the useful services to one at a time. Once that is doing I’ll probably switch to XigmaNAS so I can stick with FreeBSD. (I’ve always preferred FreeBSD). That will leave my NAS as just file storage for a while, though depending on how I like XigmaNAS I might or might not run services on that.

Odds are strongly against a 2 drive failure at your scale, though it does happen. I set my NAS up about 8 years ago, with 6 drives with raid-6 (well zfs’s version) and in that time two drives have failed years apart. When you get two hundreds of drives total in your operation you will see a dual drive failure.

Though you still really should have backups of everything you care about. Even though odds are in your favor someone reading this will lose data in their life on their NAS system.

One of each. There is a small chance that drives made in the same factory will fail at exactly the same time for the same reason when used in RAID 1. While this probably won’t happen (if it does it would be in the first month and you will hear about others with the same failures), why risk it. Besides you want hard drive makers to stay in business - all hard drives will crash in the future, the only question is when.

I didn’t take my advice for a RAID I built years ago. I just placed the order (one hour ago) to replace a WD red with a Seagate. God only knows when the next drive will fail. I’ve overall been fine, but I only have one disk redundancy in my zfs system until Thursday.

Unfortunately janky media files seem to be the rule.

You can maybe stretch that 4 hours to several days. However you must get enough solar in 4 hours to provide more than 1 day of use. You will probably get to 6-8 hours of production from your panels, but the production is reduced in the off hours and there are almost always a few clouds reducing your output even at peak times so until proved otherwise just count on 4 hours. (prove can be several years worth of data, or careful local climate calculation possibly with various devices to handle the sun moving)

How reliable do you need to be - https://solar.lowtechmagazine.com/ often goes offline because there wasn’t enough sun to keep their servers up - would this be acceptable for your servers? (you should spend a lot of time on that website when it is up - it will teach you more than anyone else here)

Will you allow yourself to plug in the backup if there isn’t much sun for a few days (either yourself or some automatic system) - just the ability to go 20 hours on battery and enough solar to recharge the battery in 4 hours on a sunny day would get most people to 90% solar and will be a lot cheaper than chasing to 100% solar all the time - but that might not be good enough for you.

The general rule of thumb if you never can go down is you need to be able to run for 2 weeks without any sun, and enough solar to then recharge those batteries when there is 4 hours of full sun. Of course the weather where you live makes a difference. If you live in the desert your worst possible day will always be followed by a day where you can completely recharge the battery so you need much less batteries; while those who live in arctic locations will not get any sun for a couple months and so need a lot more storage.

There are many who are pushing rust as a religion tan that turns people off.
