autofs with cifs filesystem creating mountpoint twice?

kayasaman · 03-23-2012, 01:11 PM

Hi,

I'm trying to use autofs to automatically mount CIFS shares but running into a strange issue.

I've followed this guide:

http://wiki.centos.org/TipsAndTricks...e1aeaa80bb20b8

and the issue I'm having is this (df output):

Code:

df: `/mnt/mysqlbackup/mysqlbackup': No such file or directory

Now my files look like this:

auto.master

Code:

#
# $Id: auto.master,v 1.4 2005/01/04 14:36:54 raven Exp $
#
# Sample auto.master file
# This is an automounter map and it has the following format
# key [ -mount-options-separated-by-comma ] location
# For details of the format look at autofs(5).
#
/misc	/etc/auto.misc
#
# NOTE: mounts done from a hosts map will be mounted with the
#	"nosuid" and "nodev" options unless the "suid" and "dev"
#	options are explicitly given.
#
/net	-hosts
#
# Include central master map if it can be found using
# nsswitch sources.
#
# Note that if there are entries for /net or /misc (as
# above) in the included master map any keys that are the
# same will not be seen as the first read key seen takes
# precedence.
#
+auto.master

/mnt/mysqlbackup	/auto.smb.top

auto.smb.top

Code:

-fstype=autofs,-Dhost=& file:/etc/auto.smb.sub

auto.smb.sub

Code:

* -fstype=cifs,user,uid=505,rw,suid,credentials=/root/.mysqlbackup.txt	://172.31.8.158/mysqlbackup

basically I've tried all combinations of putting and removing the * infront of the -fstype parameter and putting in or taking out the /mnt/mysqlbackup from the auto.master file...

whenever I try and mount using:

Code:

* -fstype=autofs,-Dhost=& file:/etc/auto.smb.sub

* -fstype=cifs,user,uid=505,rw,suid,credentials=/root/.mysqlbackup.txt	://172.31.8.158/mysqlbackup

I get some kind of recursive directory mount which was basically the df output above mysqlbackup/mysqlbackup ???

How can I just have 1 level of mysqlbackup so that the mount looks like:

/mnt/mysqlbackup/...

Can anyone help?

Thanks

I seem to have forgotten my autofs memories, so bear with me..

Why have you got the auto.smb.sub configuration file? Is the auto.smb.top doing something special? (I really have forgotten everything!)

Are you trying to mount different things depending on what directory you access?

Ok I've figured this out!

Basically I created 2 files looking like this:

Code:

auto.master file:

/mnt    /etc/auto.smbmount

auto.smbmount file:

mysqlbackup -fstype=cifs,uid=500,user,rw,credentials=/root/.password.txt 
://SAMBA-SRV/mysqlbackup

and now the autofs service works.

I think the CentOS link confused me:

http://wiki.centos.org/TipsAndTricks/WindowsShares

under method 4. which is kinda weird.

Thanks for the attepted help though.

I mean I have multiple shares/mounts which go under multiple directories; some under /mnt others under /opt/../../ etc....

So have yet to test my 'working' method out 100% but we'll see what happens!
