[Pkg-ganeti-devel] Bug#765764: Ganeti 2.12 does not create a required group gnt-wconfd

[Michael Evans]

Severity: grave
Package: ganeti-2.12

(Until I applied the workarounds I’m documenting in both bug reports Ganeti
was ‘unusable’ (jobs would not process/etc) which appears to qualify as
grave severity.  However the workarounds are trivial to apply.)

If I am reading the error message correctly, Ganeti 2.12 does not create a
required group gnt-wconfd.  This appears to be an upstream bug.  I have
submitted it as https://code.google.com/p/ganeti/issues/detail?id=976

# On /all/ nodes

#
# NOTE: Upstream does not yet have changes in the makefile.am
#  to create the users-setup with any gnt-wconfd / gnt-metad u/g
# I have /guessed/ at some values that seem to make sense and work for me.
#

addgroup --system gnt-wconfd
addgroup --system gnt-metad
adduser --system --no-create-home --ingroup gnt-wconfd --ingroup gnt-masterd
--ingroup gnt-metad gnt-wconfd
adduser --system --no-create-home --ingroup gnt-metad gnt-metad

# Then on the master node:

gnt-cluster upgrade --to 2.12

# You may also need to restart the ganeti daemons on all nodes one
additional time.

gnt-cluster upgrade --to 2.12
