Crashes & Rebuild - There was a random issue where deleting a user from Open Directory caused all Users and Groups to disappear, and for Open Directory & Xsan to revert to an un-configured state.Currently I have a user that is not able to connect to a share via SMB, but AFP works fine. User Connectivity - After adding new users to the directory they are not always able to access various services or connect to shared volumes.This mostly happens on the network storage that is hosted by "Server A". Temporary fix has been to propagate permissions weekly. File Permissions - Group ACL permissions are not always properly applied resulting in staff not being able to read/write to various folders or files.This has resulted in various problems such as: There seems to be issues with the replication of Open Directory information from the OD Master to the Replicas. Please correct me if that is not the case!
I understand there have been numerous under the hood OS & Server changes since Mountain Lion and that the OD Master is now required to be running on the machine that is serving as the Primary Xsan metadata controller. In our previous Mountain Lion (10.8.5) configuration utilizing the exact same hardware, the Open Directory Master was hosted on one of the servers that WAS NOT serving as the Primary Xsan metadata controller. File Sharing (re-sharing Xsan volume via SMB/AFP as well as another attached Thunderbolt storage device for general network storage).Connected to Xsan Volume as a Client, not a controller.Secondary (failover) Xsan Metadata Controller.Open Directory Master (as recommended/detailed in the Xsan setup information).As recommended/detailed for typical Xsan configuration, we have separate physical public (internet) and private (Xsan metadata) ethernet networks as well as a switched Fibre Channel network. I have an office environment of many El Capitan (10.11.6) clients and 3 MacMini servers running El Capitan (10.11.6), macOS Server app (5.2) & Xsan (4.1). I understand this is a complex configuration and likely beyond the knowledge of most, however hoping someone might be able to provide some insight or possible recommendations.
