Technical Tip: How to check NFS compatibility

[mbenvenuti]

Description	This articles describes how to check NFS compatibility.
Scope	FortiSIEM.
Solution	Before adding an NFS server as Online or Archive storage in the FortiSIEM or after some NFS server configuration change, it can be useful to check if it is compliant by running basic commands that FortiSIEM will perform. Follow these steps: Copy the attached script (with winscp) in the FortiSIEM node to check in the /tmp/ folder. From the super or the worker CLI as root, run: cd /tmp chmod +x nfs_checker.sh nfs_checker.sh <nfs_server_ip> <nfs_shared_folder> This script will execute basic commands and create an error if one test cannot be performed successfully. Example: nfs_checker.sh 10.5.8.5 /Share/archive ======================================================= Creating local mount point... ======================================================= Done
