Comment on Holiday Upgrade Disasters

I told myself “with this 4 days of holidays i can easily rebuild the btrfs array”. 3 days later it’s still crunching numbers at 50MB/s… (but with all this time passed at that speed the drives would be able to fully rewritten multiple times…)

And you did a backup first, right? 😉
How big’s the array? If it’s PBs, then I can understnad it, but GBs… I agree, it should be done by now…
… unless it’s still online and being written to by a database…?

Yes. Luckily I did a snapshot then copied on a separate drive using btrfs send.
I shut down everything, there’s no activity… that’s why I feel weird to see all this rebuild activity, yet so many hours passed…
A scrub usually takes less than an hour…
