Linux users familiar with other filesystems or ZFS users from other platforms will often ask whether ZFS on Linux (ZoL) is “stable”.
The short answer is yes, depending on your definition of stable. The term stable itself is somewhat ambiguous. While one would think that stable means “ready for production use”, that can mean that it does not lose data, that it does not crash, that it is a drop-in replacement for an existing filesystem, that changes to the disk format are forward compatible, that updates are always flawless or some combination thereof. Consequently, the long answer is much more nuanced than a single word can express.
