Mount Filesystem in AIX Unable to read /etc/filesystem

Dear all,

We are facing prolem when we are going to mount AIX filesystem, the system returned the following error

0506-307The AFopen call failed[etc/filesystem]
: A file or directory in the path name does not exist.

But when we ls filesystems in the /etc/ directory it show

-rw-r--r--  0  root      system 15325  Sep 19 08:05 filesystems

I dont the understand why & how the number becomes 0 instead of 1
Also iam unable to more /etc/filesystem it reutrns the same A file or directory in the path name does not exist error.

I have copy of /etc/filesystem which I want to replace with this it this one but the cp , mv all comands are failed and retruning the resource is busy message.

Any help, would be appreciated.

please post ALL commands you used with the coresponding output.

The problem has been resolved now, but we noticed that the df command shows
the following output in which /etc/filesystem was mounted with a temporary file in /tmp which causing the /etc/filesystems to be inaccessible, we unmount the /etc/filesystems and the problem got resolved.

df output:
/tmp/fs1.286834 3145728 1693376 47% 9619 /etc/filesystems

We didn't understand where the "/tmp/fs1.286834" comes from & why :wall:
we checked the "fs1.286834" in /tmp filesystem but didn't found it.

If you have any idea about please let us know.
