Over the years, I've got burn so many times with Linux network filesystems (including SMB/CIFFS, which is not all Linux but still) that I would start by recommending not to touch a network filesystem in the same host where anything important happens. The issue is with how network failures (which always eventually happen) interact with the "uninterruptible" Linux process state. Hell breaks loose, and the failure is anything but obvious.
