Public bug reported:
I have upgraded my dual boot laptop (Xubuntu 19.04 on ZFS) to 19.10, I
only had a minor problem:
The system on boot did start scrub of all datapools automatically, that was
unexpected and it took a couple of minutes before I realized, why the system
was that effing slow. There is a small chance that the monthly auto-scrub was
due. If it is part of the upgrade do not do it without at least a notification
and a confirmation of the user. Never start it during the boot process, please
wait a few minutes. The same remarks are valid for the monthly default
auto-scrub.
Even not Microsoft is allowed to monopolize my system for a long time without
telling and without my permission, that is partly why I moved to Linux :) :)
I detected it relatively fast on my conky display, but else??
Of course I stopped the scrub of the two datapools on the same SSHD and
restarted it one by one.
I'm more happy with the SSHD using ZFS and LZ4 compression.
