NFS - Rmtab file...

[Dave Cast]

Does anyone know if the rmtab file lists *only* remote mounts that are current or is it a history of mounts?

Thanks in advance.

Hi

File /etc/rmtab contains a record of all clients that mounted remote file systems from this machine. Whenever a remote mount is done, an entry is made in the rmtab file of the machine serving that file system. umount removes the entry of a remotely mounted file system.umount -a broadcasts to all servers that they should remove all entries from rmtab created by the sender of the broadcast message.

Have a look on man pages.

Best Regards,
Ramesh

The man page I have read! The question is: is the listing in rmtab list ***CURRENT*** (and I do mean current) mounts only or does it retain a history?

Looking at the rmtab on one of my systems, it appears that a history of sorts is present...as the first character of a line is changed to "#" when a file system is unmounted.

#vru3:/fedcat_large/aix
#vru3:/fedcat_large/aix
#vru3:/fedcat_large/aix
#vru3:/fedcat_large/aix
#vru3:/fedcat_large/aix
#vru3:/fedcat_large/aix
#vru3:/fedcat_large/aix

But, note the following:
