Title:
zsysd uses more than half of CPU and disk IO
Status in zsys package in Ubuntu:
Fix Released
Bug description:
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 disk 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. And there is
this error occured when I am installing or removing a software package
via apt:
ERROR couldn't connect to zsys daemon: connection error: desc =
"transport: Error while dialing dial unix /run/zsysd.sock: connect: no
such file or directory"
I think this is not a good approach
