> There are very real reasons to use ZFS
I feel like, for the types of person GP is talking about, they likely don't really need to use ZFS, and luks+md+lvm would be just fine for them.
Like the GP, I have such a setup that's been in operation for 15-20 years now, with none of the original disks, probably 4 or 5 full disk swaps, starting out as a 4x 500GB array, which is now a 5x 8TB array. It's worked perfectly fine, and the only times I've come close to losing data is when I have done something truly stupid (that is, directly and intentionally ignored the advice of many online tutorials)... and even then, I still have all my data.
Honestly the only thing missing that I wish I had was data checksumming, and even then... eh.
