La verdad es que seguí un par de tutos para montar un server NFS y un cliente NFS y aparecían dichas options en la configuración del fstab y lo seguí al pie de la letra. Revisando todos los parámetros:
nfs auto,noatime,nolock,bg,nfsvers=3,intr,tcp,actimeo=1800 0 0
auto
Can be mounted with the -a option.
noatime
Do not update inode access times on this filesystem (e.g, for faster access on the news spool to speed up news servers).
lock / nolock
Selects whether to use the NLM sideband protocol to lock files on the server. If neither option is specified (or if lock is specified), NLM locking is used for this mount point. When using the nolock option, applications can lock files, but such locks provide exclusion only against other applications running on the same client. Remote applications are not affected by these locks.
NLM locking must be disabled with the nolock option when using NFS to mount /var because /var contains files used by the NLM implementation on Linux. Using the nolock option is also required when mounting exports on NFS servers that do not support the NLM protocol.
bg/fg
Determines how the mount(8) command behaves if an attempt to mount an export fails. The fg option causes mount(8) to exit with an error status if any part of the mount request times out or fails outright. This is called a "foreground" mount, and is the default behavior if neither the fg nor bg mount option is specified.
If the bg option is specified, a timeout or failure causes the mount(8) command to fork a child which continues to attempt to mount the export. The parent immediately returns with a zero exit code. This is known as a "background" mount.
If the local mount point directory is missing, the mount(8) command acts as if the mount request timed out. This permits nested NFS mounts specified in /etc/fstab to proceed in any order during system initialization, even if some NFS servers are not yet available. Alternatively these issues can be addressed using an automounter (refer to automount(8) for details).
nfsvers=n
The NFS protocol version number used to contact the server's NFS service. If the server does not support the requested version, the mount request fails. If this option is not specified, the client negotiates a suitable version with the server, trying version 4 first, version 3 second, and version 2 last.
intr / nointr
Selects whether to allow signals to interrupt file operations on this mount point. If neither option is specified (or if nointr is specified), signals do not interrupt NFS file operations. If intr is specified, system calls return EINTR if an in-progress NFS operation is interrupted by a signal.
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 kernel 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.
tcp
The tcp option is an alternative to specifying proto=tcp. It is included for compatibility with other operating systems.
actimeo=n
Using actimeo sets all of acregmin, acregmax, acdirmin, and acdirmax to the same value. If this option is not specified, the NFS client uses the defaults for each of these options listed above.
Entiendo que la única option que podría estar fastidiándome es noatime, diría que el resto de las options no me afectan para mal.
He estado revisando las options con respecto al parámetro "atime" y he visto estas posibilidades:
- diratime
Update directory inode access times on this filesystem. This is the default.
- nodiratime
Do not update directory inode access times on this filesystem.
- atime
Do not use noatime feature, then the inode access time is controlled by kernel defaults. See also the description for strictatime and relatime mount options.
- noatime
Do not update inode access times on this filesystem (e.g, for faster access on the news spool to speed up news servers).
- relatime
Update inode access times relative to modify or change time. Access time is only updated if the previous access time was earlier than the current modify or change time. (Similar to noatime, but doesn't break mutt or other applications that need to know if a file has been read since the last time it was modified.)
- norelatime
Do not use relatime feature. See also the strictatime mount option.
- strictatime
Allows to explicitly requesting full atime updates. This makes it possible for kernel to defaults to relatime or noatime but still allow userspace to override it. For more details about the default system mount options see /proc/mounts.
- nostrictatime
Use the kernel's default behaviour for inode access time updates.
Con usar atime en vez de noatime entiendo que sería más que suficiente ¿No?
