I submitted a bug report to Redhat-bugzilla with a 3750 lines file attached (result of lsblk command, dmesg result, and logwatch report concerning systemd log after a shutdown failure. But I am a little bit pessimistic if you consider that (for instance) since f22, you can see that journalctl or watchdog are not stopped before unmounting / /var and /usr and you can see while you shutdown your system (f23, f24) that unmounting these partitions systematically fails.... This kind of small bugs remain after 4/5 years.... I am wondering why it is claimed that systemd has been introduced to increase fastness: I could see that it is not the case at boot time (10s with systemv while it is now about 30s when no "start job ......" appears during the boot sequence!) the last update I made on a f23 system blocks change of user (I have to beboot) and shutdown is very long (no raid on this system), and now, endless shutdown on my f24 system! You say that fedora uses LVM by default, but on my f24 system (raid) there are no LVM at all: pvscan, lvscan etc. return nothing while some lvm services are enabled and running (lvm2-lvmetad.socket, lvm2-monitor and lvm2-lvmpolld) what for?
