ArcGIS Data Store change to READONLY with enough disc space

Question

We have an ArcGIS Enterprise 10.6.1 site. The Data Store changed over to READONLY mode. The Threshold for READONLY mode is set to 1024MB yet the disc space on the drive where the arcgisdatastore is stored still has 36GB available of 140GB disc (just over 25% free).

Any ideas why the Data Store would change over to READONLY if there is enough disc space?

Hello Michael,

I'm not aware of any documentation regarding the Windows paging file and ArcGIS Data Store. I've seen the ArcGIS Data Store change to read-only mode before when other applications are writing to the same drive. Either temporarily or permanently reducing the available disk space.

Thanks,

Thomas.

Hello Julian,

Not to my knowledge, do you know what the available disk space was on the 😧 drive before you deleted the hosted feature service?

Is the 'arcgisportal' portal directory and install directory also located on the 😧 drive? If it occurs again I would recommend reviewing portal logs (DEBUG) and the data store logs.

Thanks,

Thomas.

Thanks for your replies.

The paging file is not on this D drive.

I deleted a very large hosted feature service. Could this somehow have used up additional disk space during the delete process and then freed it up again, causing the drive to drop below the threshold long enough to change it to read only?
