What is the meaning of these error/warning messages (f25) and how to

man lvmetad
and it will explain how lvmetad works, and why these messages are being
generated, and what they mean.
-- systemd
Failed unmounting /var.: 1 Time(s)
Requested transaction contradicts existing jobs: Transaction is

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"?
My guess is that, if it runs, information will be lost from the system,
or process sequence will be broken.
The systemd message seems pretty clear in that regard; there are
jobs running that are using /var. If it wasn't you that was trying to
umount /var, then this seems like a system error, as the system
shouldn't be trying to umount /var when jobs are running, except maybe
at shutdown.
Perhaps someone more knowledgeable can explain it better.
