Issue/Introduction

While trying to export logs from VMware Aria Operations for Logs using an NFS datastore as the destination, the operation fails with an error indicating that the NFS mount is temporarily unavailable.

The following entries can be found in the /var/log/loginsight/runtime.log file:

["Timer-6"/192.168.1.54 INFO] [com.vmware.loginsight.commons.executor.ProcessExecutor] [Finished executing mount mnt:<moount path> /storage/core/loginsight/nfsmount/admin1744862652964, ran for 125091 ms]

Environment

VMware Aria Operations for Logs 8.x

Cause

The error Resource temporarily unavailable typically indicates that the Aria Operations for Logs node is unable to mount the specified NFS share due to one or more of the following reasons:

The NFS server is unreachable or down.

Network/firewall restrictions are preventing NFS traffic.

Export permissions on the NFS server are not allowing access from the Aria operations for logs appliance.

DNS resolution issues

Resolution

To address the issue, follow these steps:

• Verify NFS Server Availability:

           Confirm that the NFS server is operational and accessible over the network.

           Test the NFS mount by connecting to the same share from a different Linux host to rule out server-side issues.

• Check NFS Export Permissions:

           Ensure the NFS export is properly configured to grant access to the IP address of the Aria Operations for Logs appliance.

           Review firewall rules or network policies to confirm that NFS traffic (typically over port 2049) is not being blocked between the appliance and the NFS server.
