We recently transferred our ArcGIS Server site config-store and directories from one machine to a network DFS location and seeing some major performance issues.
A bit about the architecture: Multi-tier ArcGIS Enterprise with 4 ArcGIS Servers participating in the site.
Till now, we had the config-store and directories pointed to a location on one of the machines; after reading this doc we decided to move both config-store and directories to a dfs location. The ArcGIS Server account has full permissions here.
You might choose to put the configuration store on a machine or disk that is not dependent on the ArcGIS Server, such as a fault-tolerant file server.
After doing so, server manager is very slow to come up (~10-15 minutes to bring up services pane). 95% of services, maps, apps etc are functional but administering services is now impossible.
Today I came access this esri doc where it says DFS is not supported.
Choose a storage device that enables files to be read immediately from any node in your site once an operation and corresponding write has completed. This disqualifies many types of distributed file systems, such as GFS and DFS.
NFS shares must be configured to ensure consistent reads and avoid using stale data caches.
Is DFS not a fault tolerant file share? Do I need to request something different from my IT. Thanks in advance.
