Unknown file system entries in the bdf output

I have 3 new ia bl860 machines running on 11.31 OS. I am seeing some strange file systems (basically copy of the "/" (slash) file system. Those which are mounted starting with "/net" are fake entries..Please see below the bdf o/p.

======================================
b201u005 is the hostname. b201u00b is another aliase to the hostname (the backup lan interface). It picks these entries from /etc/hosts file..These entries are neither present in fstab or autodirect..If we reboot the machie, it gets cleared off, but again it comes back after sometime..If you do ll , it will list you the "/" contents..basically these are pointing to "/". I tried to umount the these false entries, but it said, device busy, can be unmounted (since it's "/")..
I am seeing these entries in syslog file:

Jun 3 00:01:18 b201u007 sshd[22991]: ERROR: Unexpected error in conversation: (6)

================================
The IPs mentioedn here doesn't resolve to these hosts..except the loop back..I think these eerrors in syslog are common and nothing to do with this issue..but still just pasted for your reference..can anyone please suggest a solution here..It's a big pain for me..

Re: Unknown file system entries in the bdf output

Shalom,

Check your .sh_history file for mount commands.

It it important to know how these mounts were made.

I think you need to umount them or shut down the automount configuration that made them and make sure all the IP and hostnames being used resolve properly before firing this up.

What is happening is not good, and I do not thing the current setup is reliable.

Re: Unknown file system entries in the bdf output

check /etc/auto.direct file if your not using automount ..then try disabling it and see the result..
