Package: autofs
Version: 5.0.7-3
Severity: normal
Dear Maintainer,
* What led up to the situation?
Upgraded from squeeze to wheezy.
* What was the outcome of this action?
With squeeze (and lenny) I was able to use one automount map via ldap to
nfsmount fileserver:/home on client:/nfs/fileserver/home on remote boxes and
locally on the fileserver itself. With wheezy on only the fileserver the
incorrect directory ("/") is automounted. It appears that in trying to be
"efficient" and using bind mounts autofs is ignoring the fsid parameter in
/etc/exports.
* What outcome did you expect instead?
Like remote clients the fileserver should be able to use the same map and get
/home automounted.
Thanks,
Chris
$ grep fsid /etc/exports
/home
192.168.1.0/24(ro,fsid=0,no_root_squash,subtree_check,insecure,crossmnt)
On a client I see the expected directories:
$ ls /nfs/fileserver/home
chrisd fai lindad mythtv svn tftp www
$ mount | egrep auto\|fileserver
ldap:ou=auto.nfs4,ou=autofs,dc=zoo on /nfs/fileserver type autofs
(rw,relatime,fd=7,pgrp=4217,timeout=300,minproto=5,maxproto=5,indirect)
fileserver:/ on /nfs/fileserver/home type nfs4
(rw,relatime,vers=4,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=192.168.1.28,minorversion=0,local_lock=none,addr=192.168.1.23)
Stopped autofs and restarted it in debug mode and issued the same commands on
the fileserver and see "/" instead:
$ ls /nfs/fileserver/home
altroot bin boot data dev disk etc home initrd.img lib lib32 lib64
media mnt nfs opt proc root run sbin selinux srv sys tmp usr var
vmlinuz
$ mount | egrep auto\|fileserver

/dev/mapper/zoo-root2 on /nfs/fileserver/home type ext3
(rw,relatime,errors=continue,barrier=1,data=ordered)
On the fileserver during the local mount:
