I want to make a NAS with a 500GB boot drive and 2x16TB HDDs.
Based on my previous post, btrfs is a good option. It also looks easy to get started.
My plan for the NAS would be to purchase several 16TB drives, and only use 2 of them.
My first question is about different drives.
Could I purchase two different brand drives and use them with btrfs? (I assume yes)
2nd question: how does the replacement process go? Like if drive A died, so I remove it, and put a brand new replacement in. What do I have to do with btrfs to get the raid 1 back going?
Any links or guides would be amazing.
In days past some drive vendors had different sector layouts for drives and would cause issues with raid. Pretty sure most nowadays are all the same layout and you won’t run into any issues. I still look to get the same drive model anyways just to be perfectly sure that there are no issues.
Even then you may run into weird issues like one of my 1.2 TB enterprise ssd drives was reporting 1.12 TiB rather than 1.09 TiB the other 7 drives had. TrueNas refused to build a vdev with that drive and I had to return it to get a new one.
