Hello Brian,
Thank you for the reply and sharing your design. Can you please share
your MariaDB server HA details.? ( Can be offline and DM to me )
I would like to understand it so that I can replicate it here.
Thanks & regards,
Richard.

RC,
In that scenario, the backup slurmdbd would take over, but then its
database would not necessarily be in sync with the 'main' database
(hence the warnings/info about it in the documentation).
For my setup, I have 2 slurmdbd hosts, but they both connect to the
same, separate, MariaDB serv
Does it mean it is best to use a single slurmdbd host in my case?
My primary slurmctld is the backup slurmdbd host, and my worry is if the
primary slurmdbd host ( which is also the mariadb server) goes down,
will the backup slurmdbd be able to cache data and wait till the mariadb
catches up ?
Ole,
Fair enough, it is actually slurmctld that does the caching. Technical
typo on my part there.
Just trying to let the user know, there is a window that they have to
ensure no information is lost during a database outage.

Have you found any documentation of slurmdbd caching? It's well-known

Hi,
Just for my info, I would like to know what happens when SlurmDBD loses
connection to the backend Database, for ex, MariaDB.
Does it cache the accounting info and keep them till the DB comes back
up ?, or does it panic and shut down ?
Thank you,
RC.
