dino99, can you please do

  journalctl -ab > /tmp/journal.txt

and attach it here?

Didier, can you please have a look at this?

[dino99 (9d9)]

that systemd-fsck have appeared after having upgraded an other vivid installation (64 bits) on its own partition, sharing the swap partition but not /home.
Booting back on that vivid 32 bits, systemd-fschk was ran and terminated as expected, excepted for that plymouth error.

[dino99 (9d9)]

note2: as fschk has not been used since that error, this error has not then been seen indeed. But i suppose there is an issue connecting to plymouth in such a case.

[Didier Roche (didrocks)]

dino99: I guess plymouth wasn't running for you when fsck started, right?

I conditioned the fact that the messages are sent to plymouth if the pid file is present (see http://lists.freedesktop.org/archives/systemd-devel/2015-March/029174.html)

[dino99 (9d9)]

@Didier

this is a vivid i386 with a gnome-shell session; so i suppose that plymouth is always used while logging (as expected by default, but i admit i rarely care about it as that process is quite hidden for user) and i suppose it is deactivated when the login is done.

now when i got that systemd-fsck i cant tell if plymouth was already activated or not yet. That 'connection refused' looks unecpected when fsck is ran as that job is done way before login time, so plymouth should not be disturbing it.

@dino99: As I said on the other bug: please stop running your machines with "debug" and getting scared by debug messages :-) (that's another one)

[dino99 (9d9)]

@Martin

as i remember, 'debug' was not used when that issue was seen

Seems related to that issue:

ubuntu-gnome-default-settings (15.04.3) vivid; urgency=medium

  * Add fsck report and cancel support with systemd to the logo theme

Feedback

after having made a few upgrades on utopic/vivid64, when i came back booting vivid32, i got this logged again into journalctl:

systemd-fsck[507]: lhom: Superblock last write time is in the future.
systemd-fsck[507]: (by less than a day, probably due to the hardware clock being incorrectly set). FIXED.
systemd-fsckd[246]: Couldn't connect to plymouth: Connection refused

but except these lines logged, the fsck job was done as expected; so looks harmless.

[dino99 (9d9)]

Still not approved upstream ?

Today i got /home fsck'ed, and got that error logged ~100 times:

systemd[1]: Starting File System Check on /dev/disk/by-uuid/5d8d1ee...
systemd[1]: Started Copy rules generated while the root was ro.
systemd-fsck[499]: lhom has been mounted 35 times without being checked, check forced.
systemd-fsckd[235]: Couldn't connect to plymouth: Connection refused
....
....
systemd-fsckd[235]: Couldn't connect to plymouth: Connection refused
systemd-fsck[499]: lhom: 61728/9420800 files (13.0% non-contiguous), 11832540/18820785 blocks
systemd-fsckd[235]: Couldn't connect to plymouth: Connection refused

that is, the fsck process has terminated as expected (full fschk done), but plymouth should not be trying to connect while doing a fsck (maybe not easy to do as systemd have parallel tasks running)

This bug was fixed in the package systemd - 219-6ubuntu3

---------------
systemd (219-6ubuntu3) vivid; urgency=medium

  * Merge fixes from Debian experimental branch:
    - Fix display-managers autopkgtest race.
    - Enable timesyncd in virtual machines.
    - fsck, fsckd: Grab various fixes from upstream git. Amongst others, this
      suppresses "Couldn't connect to plymouth" errors if plymouth is not
      running. (LP: #1429171)
