I don't want to make a specific statement regarding corruption
but I can explain how nbmand works and let you decide on what
to do.
The locking facility exists centrally within the OS and all
access (local, NFS or SMB) always goes through it regardless
of whether it is on or off. The only differ
If nbmand is off there won't be much coordination between
SMB and NFS accesses to the same file and it could potentially
lead to file corruption.
If you don't have simultaneous access to the same files over
both protocols then you don't need to worry about turning nbmand off.
