| ZFS is great, but it does break from time to time Ah, it seems our definitions vary. ZFS has had problems, but all production filesystems have. From a strict standpoint, what the original author wrote about bugs is wrong, but from a practical standpoint I don't think it matters. ZFS has been as solid as any other production filesystem from the beginning -- which is to say that any production filesystem might one day rear up and bite you. It's just the nature of our profession. That's just my opinion though. :) Scrubbing repairs data, not broken file systems. That depends what's broken. ZFS has ditto blocks (multiple copies of the same block) going up the tree; roughly speaking, the higher up you are, the more there are. The tree and metadata has more protection than the data itself. If, say, all the ditto blocks and all the mirrors are corrupt, reconstructing that is going to be hard. I think a case needs to be made that an fsck tool would do a better job repairing than scrubbing, which is non-obvious to me. |
