SYMPTOM:
In a clustered or non-clustered configuration, it is possible to set up a remote location for centralized cache or inbox storage. The following Strategy Knowledge Base technical note details the steps on how to configure a remote cache/inbox storage location:
KB441125: How to configure Cache, Cube, Inbox, and Session Recovery file sharing for a MicroStrategy Intelligence Server cluster
If the Strategy Intelligence Server(s) are running as root and the remote location is shared via NFS, it may be noticed that the cache/inbox directories and files are created with an ownership set to the 'nobody' user. This can cause issues if not all files are owned by 'nobody', for example if the central file location resides on the same machine as one of the cluster nodes.
CAUSE:
This behavior is due to the Strategy Intelligence Server(s) running as root and accessing the NFS share as the root user. By default for security purposes, NFS will mask all read and write operations by a remote root user as the 'nobody' user. This prevents a user with root access on one machine from accessing the files on the NFS server machine as root when they may not have root access normally. This feature is called in NFS 'root squashing'.
ACTION:
Discuss with the system administrator(s) how to address any issues which may arise from NFS root squashing. Two possible scenarios are:
