File system considerations for the NFS protocol

Ensure that all IBM Storage Scale file systems, which export data via NFS, are mounted with the syncnfs option to prevent clients from running into data integrity issues during failover.

Linux® operating systems

On Linux operating systems, the IBM Storage Scale syncnfs setting is the default mount option.

AIX® operating system

On AIX, the IBM Storage Scale nosyncnfs setting is the default mount option.

Enter the following command to change the setting to syncnfs:

# mmchfs fileSystem -o syncnfs

Enter the following command to verify:

# mmlsfs fileSystem -o
