I am using SLES 9 with NFS+autofs(3.1.7)



There are 3 Servers, say A, B & C

DIR1 is a share @ A
DIR2 is a share @ B

Want to mount the two Directories on Server-C.

In normal scenario it works, but here the problem is that they want to mount DIR1 on SHARE directory of Server-C, and mount DIR2 under DIR1
I.e.
1) DIR1 of Server-A -> Server-C/SHARE/DIR1
2) DIR2 of Server-B -> Server-C/SHARE/DIR1/DIR2

The first one is working properly, but when we implement the 2nd one, since remounting happens for DIR1 the contents are not accessible.

How to implement this?

Pretty sure this can no longer be done because of data corruption resulting from inode conflicts. That said there is a no-hide option still in the man pages. Even if you can get it to work; would want a really good backup system in place.

The Linux automounter(3.x & 4.x) does not support direct maps or mount trees
ie more than one filesystem to be mounted under a specific automount point

5.x version of automounter have this facility but i don't want to migrate to that.
Is there any other alternative?
