man -LC 5 nfs
soft / hard Determines the recovery behavior of the NFS client after
an NFS request times out. If neither option is speci‐
fied (or if the hard option is specified), NFS requests
are retried indefinitely. If the soft option is speci‐
fied, then the NFS client fails an NFS request after
retrans retransmissions have been sent, causing the NFS
client to return an error to the calling application.
NB: A so-called "soft" timeout can cause silent data
corruption in certain cases. As such, use the soft
option only when client responsiveness is more important
than data integrity. Using NFS over TCP or increasing
the value of the retrans option may mitigate some of the
risks of using the soft option.
Wenn man, weiss warum der Prozess hängt, reicht es vielleicht ihn zu killen:
intr / nointr Selects whether to allow signals to interrupt file oper‐
ations on this mount point. If neither option is speci‐
fied (or if intr is specified), system calls return
EINTR if an in-progress NFS operation is interrupted by
a signal. If nointr is specified, signals do not inter‐
rupt NFS operations.
Using the intr option is preferred to using the soft
option because it is significantly less likely to result
in data corruption.
The intr / nointr mount option is deprecated after ker‐
nel 2.6.25. Only SIGKILL can interrupt a pending NFS
operation on these kernels, and if specified, this mount
option is ignored to provide backwards compatibility
with older kernels.
