I have an NFS problem on a Redhat Ent Linux 5 host, in that I want to mount some NFS shares on
There are also some other dirs and files in
/opt/test, etc which we want to access while the NFS shares are mounted.
Currently the NFS shares mounted on boot from
/etc/fstab and all works well.
However we want to mount
/opt/stage on demand via autofs/automounter instead of on boot from
I have this configured such that the NFS shares mount OK with autofs/automounter but
when the automounter mount the NFS shares on the mount points I can not see the other files in
Is it possible to use the automounter to mount the NFS shares on
/opt/stage and still be able to access the other files in
If so how?
I have run a demo session which has been pasted it in below with some comments to try and help explain the problem.
Here's the demo:
# /opt has the two mount point dirs "backup" and "stage" as well as the dirs "lost+found"
# "myapp" "otherapp" and the file "test"
[root@jttest6 etc]# ls /opt backup lost+found myapp otherapp stage test
# We list the NFS mountpoints - there are no files, the NFS shares are not
# mounted (Autofsd is not running at this point)
[root@jttest6 etc]# ls /opt/backup [root@jttest6 etc]# ls /opt/stage
# This is what is in /etc/auto.master
[root@jttest6 etc]# grep -v ^# /etc/auto.master /misc /etc/auto.misc /opt /etc/auto.opt /net -hosts +auto.master
# This is what is in /etc/auto.opt
[root@jttest6 etc]# cat /etc/auto.opt backup -rw,soft,intr,rsize=8192,wsize=8192 nfs.icesa.catholic.edu.au:/opt/backup stage -
# we start autofs
[root@jttest6 etc]# service autofs start Starting automount: [ OK ]
# we list the NFS mountpoints (I pipe into head because the listings are long - this
# is sufficient to show that something is now mounted there)
[root@jttest6 etc]# ls /opt/backup|head -2 ACL brocade-backups [root@jttest6 etc]# ls /opt/stage|head -2 ADF ApplicationServer101202
# However we have now lost access to the dirs "lost+found" "myapp" "otherapp" and the file "test"
[root@jttest6 etc]# ls /opt backup stage
