CIFS mount twice

CIFS mount twice

[Aravind M D]

Hi,

  I have some cifs mount points configured on my /etc/fstab.

  When i am doing mount -a command mount points are mouting again.

  If mount command is issued mount point is showing twice.

  If i use mount through command line also i am facing the same issue.

  Please help me.

  Rgds,
  Aravind M D

Not with the description you've given as there's just hardly anything
there in the way of details...

I set up my fedora rawhide test box with a cifs mount in /etc/fstab and
then ran mount -a several times. It was only mounted once.

IIUC, it's the job of /bin/mount to only attempt to mount filesystems
that have not already been mounted when mount -a is run. If that's not
happening on your machine then it sounds like something is broken there.

Hi Jeff,

I have SLES 11 SAP systems on which some CIFS FS are configured on /etc/fstab.

~#cat /etc/fstab
//oese-sc1-osi01/osiris1       /oese-sc1-osi01/osiris1/
cifs                  username=user1,password=pass1,uid=200,gid=200
//oese-sc1-osi02/osiris2       /oese-sc1-osi02/osiris2/
cifs                  username=user1,password=pass1,uid=200,gid=200
//oese-sc1-osi99/osiris0       /oese-sc1-osi99/osiris0/
cifs                  username=user1,password=pass1,uid=200,gid=200

Already these FS are mounted on my system. When i run mount -a and mount
command below is the output.

~#mount

//oese-sc1-osi01/osiris1 on /oese-sc1-osi01/osiris1 type cifs (rw,mand)
//oese-sc1-osi02/osiris2 on /oese-sc1-osi02/osiris2 type cifs (rw,mand)
//oese-sc1-osi99/osiris0 on /oese-sc1-osi99/osiris0 type cifs (rw,mand)
//oese-sc1-osi01/osiris1 on /oese-sc1-osi01/osiris1 type cifs (rw,mand)
//oese-sc1-osi02/osiris2 on /oese-sc1-osi02/osiris2 type cifs (rw,mand)
//oese-sc1-osi99/osiris0 on /oese-sc1-osi99/osiris0 type cifs (rw,mand)

Mounts are showing twice.

I have tested the same on Debian 6 also i have faced same problem. But in
the debian 6 i tried upgrading the cifs-utils to the latest version.

Once cifs-utils was upgraded the mount -a will mount partition only once.

But when i mount the same FS using command line in debian it will show twice.

Why CIFS FS is mounting on already mounted mount points.

I tried a few experiments here, and although I get different errors
with /sbin/mount.cifs present vs. without, I don't see the problem
you a describing.   First obvious question ... what version of
cifs-utils are you using.   Type "/sbin/mount.cifs -V" to
see if you are using the roughly the same version on all.

Looks like you are hitting problems with older version of cifs-utils.

I ran the "mount -a" tests on openSUSE 11.4 and SLES11 SP1 but I could
reproduce this problem. I don't have a SLES11 setup. I'll see if I could
get one. Some useful information that'll help include

a) version of cifs-utils/cifs-mount
b) version of util-linux
c) mount -a -vvv output


OTOH, if you have a support contract with SUSE/Novell, please open a bug
report on https://bugzilla.novell.com agaist the product and include me
in the Cc.

You might have to use "rpm -qa | grep cifs-mount" to find the version.

Also try upgrading cifs-mount package. "mount -a" mounting cifs mounts
twice atleast  is not reproducible with the recent updates.
