And to complement the other comments, the ZFS developers quit Oracle when it was made proprietary and moved on to work on OpenZFS, which has continued evolving.
Yes, agree. However, I also lost files on it (had files overwritten with 0s, as other people already commented here). Also, it's your best bet of you don't need the extra features provided by ZFS. Thanks to its checksum validation, I detected bad SATA cables three times already (on different systems), instead of getting corrupted data.
>it was beautifully designed and implemented by SGI back in the day. Hopefully the ChatGPT generation don't start modifying that code too much.
Except it's not what happened. Please check this talk from Dave Chinner, where he explains how XFS was developed and ported to Linux and then made robust and stable by him and other contributors. The disk format has changed many times, now it's robust and resilient against metadata corruption.

44:16 "[paraphrasing Bryan C.] I told Oracle management if they changed the license, the core ZFS would quit. And they lost all the ZFS team."
