Mount options

[Former Member]

We have a filesystem mounted via NFS on 2 systems, both are automounted. When we run a bdf command de filesystem doesn’t appear, but if we try to access to the filesystem we can. We would like to know if there’s any recommendation about the mount options for filesystems.

Jesus,

Have you looked at the options for the command? Many of the Unix file system commands will ignore mounted directories by default (I believe 'du' does it that way) but have a switch to include these.

Hope that helps.

The directory is mounted by autmount when you access that directory.

This is exact automount functionaility.

This is why you cannot see in the output of "df" command when you are not using.

The recommended NFS mount option could be ...

if you use NetApp filer as NFS server,

this techinical white paper could be helpful.

Correct NFS mount options are important to provide optimal performance and system stability.
