Public bug reported:
I was installed Ubuntu 20.04 with zfs yesterday, it was OK until a few
updates, after that the zsysd was started draining CPU and IO. How can I
fix it to back to normal? Is it possible to rollback recent system
state? If Yes, just how?
NOTE: I was stopped and disabled zsysd service and removed zsysd.socket
file, after that it worked normally for now. I just don't know is this
good approach? or not.
