Limit the size of the ArcGIS Data Store

DavidHorsey

Hi. We're running a base deployment of ArcGIS Enterprise v11.5 on Windows servers. Our Data Store recently filled up the drive Enterprise is installed on which caused us some problems and it's got me thinking about how we can prevent this from happening again.

Governance plays a part in this, but for this post I'm more interested in what technical solutions we can put in place. If (when?) the drive fillls again we can always grow it but I'd rather catch the problem before the drive fills up. We have some basic server monitoring which helps, but I'd like a failsafe mode. I think the Data Store is a Postgres database under the hood - if so, is it possible to set this so it doesn't grow beyond a certain size and saves the drive from filling up?

What other strategies do people have in place to prevent this scenario?

I would suggest using the DataStore command line tools to set the disk threshold higher than the default of 1GB changedbproperties | ArcGIS Enterprise on Windows and Linux documentation. When the limit is met, Enterprise goes into a read-only state, giving you time to figure out how to move forward without everything crashing out. It's the same as adjusting the postgres instance directly, but is supported by esri.

Hello @DavidHorsey, I find the ArcGIS Enterprise email notifications* quite handy for low disk space alerts. Do you already have them set up?

In general, I don't think there are any ways to limit the size of a PG DB. You could look into setting tablespaces, but I don't think that will get you what you want in this case. You'd essentially be in the same situation you're in now.

I think the best way to do this would be to setup some sort of monitoring mechanism like you're already doing now. You could create an alert at the DB level to alert you if the DB crosses a certain size threshold. This could be done through a scheduled job that runs at every X interval.

Thanks @RClavero, It's good to know Portal offers that option, but my preference is to receive notifications from our monitoring system - this gives me more control over the alert thresholds.

Thanks @RyanUthoff. I guess decent governance, using appropriate alerting thresholds and maintaining sufficient headroom on the drive should sufficiently reduce the likelihood of a large data upload sending the system crashing to its knees 🤞

This looks like the kind of thing I was after, thanks @ReeseFacendini_MadCo!
