As mentioned in Doing a bit of stress work on a new HDD, I have a failing 5TB drive which is going to be replace by a 4TB drive. Only about 1.45TB are used, so there’s plenty of space to grow. If you get one thing from this post, don’t be downsizing zpools like this. I would have had much less work and opportunity for error, if I had returned that 4TB drive […]| Dan Langille's Other Diary

The pool can still be used, but some features are unavailable. action: Enable all features using 'zpool upgrade'. Once this is done, the pool may no longer be accessible by software that does not support the features. See zpool-features(7) for details. scan: scrub repaired […]| Dan Langille's Other Diary
For a few days now, this drive in x8dtu has been having a hard time. I think it’s time to buy a replacement. Or two.
