What is the meaning of these error/warning messages (f25) and how to correct the config to get rid of them:
-- LVM Daemon lvmetad returned error 104: 1 Time(s) WARNING: Failed to connect to lvmetad. Falling back to device scanning.: 2 Time(s) WARNING: lvmetad is being updated, retrying (setup) for 10 more seconds.: 1 Time(s)
-- systemd Failed unmounting /var.: 1 Time(s) Requested transaction contradicts existing jobs: Transaction is destructive.: 1 Time(s)
lvm2-lvmetad.socket: Failed to queue service startup job (Maybe the service file is missing or not a non-template unit?): Transaction is destructive.: 1 Time(s) lvm2-lvmetad.socket: Unit entered failed state.: 1 Time(s)
What does mean "Transaction is destructive"?
Thank you
