Subject: [PATCH] multipath: fix systemd timers in the initramfs
|
|
|
8b67ad |
|
|
|
8b67ad |
The systemd timers created for "find_multipaths smart" conflict with
|
|
|
8b67ad |
shutdown.target, but not with initrd-cleanup.service. This can make
|
|
|
8b67ad |
these timers trigger after the inirtd has started shutting down,
|
|
|
8b67ad |
restarting multipathd (which then stops initrd-cleanup.service, since it
|
|
|
8b67ad |
conflicts). To avoid this, make sure the timers and the unit they
|
|
|
8b67ad |
trigger conflict with inird-cleanup.service. Also don't make them start
|
|
|
8b67ad |
multipathd. "multipath -u" will not return "maybe" if multipathd isn't
|
|
|
8b67ad |
running or set to run, and since we no longer wait for udev-settle,
|
|
|
8b67ad |
multipathd starts up pretty quickly, so it shouldn't be a problem to
|
|
|
8b67ad |
not trigger it here.
