I decided instead to use ZFS. Better protection than just letting something sit there. Your backups are only as good as your restores. So, if you are not testing your restores, those backups may be useless anyway.
ZFS with snapshots, replicated to another ZFS box. The replicated data also stores the snapshots and they are read-only. I have snapshots running every hour.
I have full confidence that my data is safe and recoverable.
With that said, you could always use M-disk.
Any reason why that board? Not 100% sure what you are trying to do, but it seems like an expensive board for a home NAS. I feel like you could get more value with other hardware. Again, you don’t need a raid controller these days. They are a pain to deal with and provide less protection when compared to software raid these days. It looks like the x16 can be split on that board to be 8/8, so if needed you can add an adapter to add 2 nvmes.
You can just get an HBA card and add a bunch of drives to that as well if you need more data ports.
I would recommend doing a bit more research on hardware and try and figure out what you need ahead of time. Something like an ASRock motherboard might better in this case. The epyc CPU is fine. But maybe get something with rdimm memory. I would just make sure it has a Management port like ipmi on the supermicro.
You don’t need zfs cache. Stay away from it. This isn’t going to help with what you want to do anyway. Just have enough RAM.
You need to backup your stuff. Follow the 3-2-1 rule. RAID is not a backup.
Don’t use hardware raids, there are many benefits to using software these days.
With that said, let’s dig into it. You don’t really need NVMe drives tbh. SATA is probably going to be sufficient enough here. With that said, having mirrored drives will be sufficient enough as long as you are backing up your data. This also depends on how much space you will need.
I just finished building out my backup and storage solution and ended up wanting NVMe drives for certain services that run. I just grabbed a few 1 TB drives and mirrors them. Works great and I do get better performance, even with other bottlenecks. This is then replicated to another server for backup and also to cloud backup.
You also haven’t said what hardware you are currently using or if you are using any software for the raid. Are you currently using zfs? Unraid? What hardware do you have? You might be able to use a pice slot to install multiple NVMe drives in the same slot. This requires bifurcation though.
There are a few services out there that do this. They are basically job tracking sites, but a lot of them now use something like chatgpt to tailor your resume to a job description. I do recommend these services to track jobs you applied to, but they are not always the best in rewriting your resume.
One thing I have done is create a section of skills that closely match the jobs I am applying for. You can then use chatgpt API and create a prompt. This makes it easier so that all you need to do is give it the job description and it will tailor those skills sets to the job and I then just copy and paste that into my resume.
Ok but containers generally have a lot less dependencies. If you are making your own images, then you know exactly how to rebuild them. In the event something happens, it makes it much easier to get up and running again and also remember what you did to get the service running. The only other thing that would be better is Nix.
If you use an image that someone is maintaining, this makes it even easier and there are services out there that will keep your containers up to date when a new image is available. You can also just automate your image builds to run nightly and keep it up to date.
I’ll have to give this another try. I tried it before and I stopped using it for a reason that I don’t remember. It looked promising though.
I know what you mean. There are tools I see everyday and I ask, but why? I have started to just ask, why not? There doesn’t always have to be a use case and sometimes people just want to create shit. They don’t even care if others use it, but want to share it anyway in case there is that one other person that does.
Does there need to be a need? Some people just like to create things to see if they can. Some people like TUIs. There may not be a huge need for this, but it’s pretty freaking awesome to have.
I didn’t even know this was a thing. This worked for me.
That sounds like a really good idea. You basically get the best of everything.
The cool thing about ZFS is the pool information is stored on the disks themselves. You can just plug them in and import the pools.
