>Как отключить кэширование файлов, расположенных на NFS (SMBFS)? Вообще отключить, на сколько я знаю, нельзя, есть несколько других параметров.
acregmin=n The minimum time in seconds that attributes of a regular file should be cached before requesting fresh information from a server. The default is 3 seconds.
acregmax=n The maximum time in seconds that attributes of a regular file can be cached before requesting fresh information from a server. The default is 60 seconds.
acdirmin=n The minimum time in seconds that attributes of a directory should be cached before requesting fresh information from a server. The default is 30 seconds.
acdirmax=n The maximum time in seconds that attributes of a directory can be cached before requesting fresh information from a server. The default is 60 seconds.
actimeo=n Using actimeo sets all of acregmin, acregmax, acdirmin, and acdirmax to the same value. There is no default value.
