Since it was not reported that user data was impacted, it seems likely that there was a read failure (or bad checksum) for ZFS metadata which is redundantly stored.
(Maybe I am too much of a linguist to not stumble over the wording here.) If it is 'redundant', it is 'recoverable', am I right? Why, if this is the case, does scrub not recover it, and scrub even fails to correct the CKSUM error as long as it is flagged 'unrecoverable', but can do exactly that after the 'clear' command?
Ubuntu Linux is unlikely to notice data problems unless the drive reports hard errors. ZFS is much better at checking for errors.
No doubt. But ext3 also seems to need much less attention, very much fewer commands. Which leaves it as a viable alternative. I still hope that one day ZFS will be maintainable as simple as ext3; respectively do all that maintenance on its own. :)
