This feels like such a beginner question to be asking on Lemmy, let alone the tech community, but how does one go about setting up a RAID array to have my data mirrored? I only know the basics I remember about raid 1 and raid 0.
Is this RAID array something you can do without one of those “multi-hard drive units”? I have 2 16TB hard drives that I’d like to have one as a mirror copy of the first as a backup that updates at the same time but they feel too big to fit into one of those units. But maybe setting up a RAID array could be done programmatically.
I’d love and appreciate if anyone could point me in the right direction!
nowadays RAID is done with software, on linux if possible. common choices are ZFS and md-raid. you connect drives with SATA or SAS to a computer, and you can add them to a pool. drives added to pool will be formatted once.
hardware raid is discouraged, because if the RAID card fails you need a replacement of the exact same kind, with same firmware version, and they can have other difficulties too that software RAID solutions don’t.
That’s great, I’d love to not have to buy one of those machines, and I have been running my JF on a laptop just running Linux with a single one of the 16tb drives.
If the drives added to the pool need to be formatted, is there a possibility that it wipes the data on it? I’ll take a bit of time to read up on some of the options you mentioned.
Yeah fortunately mine are all in RAID arrays, hopefully none die in the next year or I may have to run degraded.
