Dear Maintainer,
Setting the WORK_DIR env variable in /etc/default/garb (involving the
use of garbd's not very documented -w option), in order to have a
cluster tracking file on the arbitrator system prevents garbd to
start, with these typical error lines:
Nov 22 19:10:32 deb12-ga garb-systemd[940]: options:
gcs.fc_limit=9999999; gcs.fc_factor=1.0; gcs.fc_single_primary=yes
base_dir=/tmp;

Nov 22 19:10:32 deb12-ga systemd[1]: garb.service: Main process exited,
code=exited, status=1/FAILURE
Nov 22 19:10:32 deb12-ga systemd[1]: garb.service: Failed with result
'exit-code'.
Actually garbd's C++ code builds an internal option string similar to
mariadb ('s galera-4 plugin) 's wsrep_provider_options. It simply
fails to add a comma separator between gcs.fc_single_primary=yes (a
fixed option always set internally) and the base_dir= option.
I couldn't find a workaround without recompiling galera-arbitrator-4
and adding the missing comma.
Doing this makes the -w/WORK_DIR option behave as intented
I believe this error has always been here but there weren't any
complains about it.
I initially considered reporting this upstream but didn't attempt it
when I discovered this had already been reported (with a very similar
fix) there more than a year ago without result:
