Because we try to make things "easier" (no failure on startups because
the lack of configuration files, for example). Of course having a HA
cluster is something beyond the scope of this bug and it might require
an experienced system administrator to be able to make corosync to work
in a meaningful way.
Nevertheless, for any future bug readers, may I recommend the following
reading:
https://discourse.ubuntu.com/t/ubuntu-high-availability-shared-scsi-
disk-environments/14874
in order to get a simple, yet supported, cluster configuration in a
shared scsi environment.
Thanks for reporting this.
