3.4.0 MxFS for CIFS Administration Guide

Chapter 3: Configure CIFS with Virtual CIFS Servers 17

If CIFS detects that a Virtual File Share can no longer be accessed on the

primary node, by default Matrix Server will fail over the associated

Virtual CIFS Server to one of the designated backup nodes. Clients then

access the Virtual CIFS Server’s Virtual File Shares from that node.

Because the files associated with the Virtual File Shares are located on a

PSFS cluster filesystem, the backup node can immediately access the

data.

By default, the Virtual CIFS Server will remain active on the backup node.

However, you can customize the failover and failback behavior. For

example, after access to the Virtual File Share is restored on the original

node, you may want the Virtual CIFS Server to fail back to that node.

CIFS clients use a Virtual CIFS Server to access file share
