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. ** Affects: zfs-linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1843296 Title: ZFS auto scrub after upgrade to Xubuntu 19.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zfs-linux/+bug/1843296/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
