Re: [Samba] Cifs mount in samba

[Андрей Гребенников]

I'm sorry, I understand that I didn't describe the process.

Well, I have a windows file server which shares its resources, for 
example \\windowsserver\share. This folder includes anothers like 
share\folders\1\ and share\folders\2\. Windows users can see them correctly.
I have remote linux server, which is a file server too, and it shares 
its resource looked like \\linuxserver\Everyone.
I try to mount the \\windowsserver\share\folders to one folder which it 
inside the Everyone, for example /mnt/Everyone/Remote, as cifs. In the 
end of such moves user lists the  share \\linuxserver\Everyone\Remote 
and sees two zero files 1 and 2. Then he refreshes the folder by F5 and 
these files transform to folders. This issue happens with all folders 
inside the Remote folder. Next users see these folders right until I 
restart samba service.

Hi people!
Help me please with a cifs mount in samba. When I mount a cifs
resource to a folder which is a part of samba share, users get all
folders in it as zero files. They press F5 or refresh, and folders
become ordinary ones. The issue repeats with all folders inside
it. How to resolv this issue?

Seriously, you're missing a lot of information. What version of Samba 
are you using? What CIFS client, Windows, Linux, or something else? 
And what you mean by "mount a CIFS resource to a folder which is a 
part of a samba share" is a bit unclear. Describe the exact process.

Hi,

that is my dfree command ( I added simple logging )

#!/bin/sh
/usr/sbin/df -k  $1 | /usr/bin/tail -1 | /opt/csw/bin/gawk '{print $2" "$4}'
/bin/echo $1 | /usr/bin/logger -t smbd_dfree_args -p local7.notice
/bin/echo `pwd` | /usr/bin/logger -t smbd_dfree_cwd -p local7.notice

the output is like that :
$/usr/local/bin/dfree
629145600 354102404

df output  for nfs share looks like that:

df -k |head-1
Filesystemkbytesused   avail capacity  Mounted on

cd /home/mygroup/myuser
df -k .
nfsserver:/users/myuser
 629145600 275043196 35410240444%
/home/mygroup/myuser



df -k for local fs:

localzfs/users/myuser
 1948778496 42750990 914183310 5%
/home/mygroup/myuser



nevertheless when I access nfs share via samba I get no free space .
with local fs it is ok .
The same happens in windows when one maps a network drive.

I will check again tomorrow, but may be I am missing something simple 
and obvious ?


Thank you,
Alex

Well, for a samba user in passdb.tdb, you still need the unix
user underneath. For a normal (non-clustered) samba server you
can create the unix users automatically when adding the samba
user with the help of a "add user script" configured in smb.conf.

I assume that in your case you either had a unix user pre-created
or used a "add user script" - right?

In a ctdb-cluster, the passdb.tdb is automatically synchronized
in the cluster, but the unix users aren't. This is the reason
why you have the proper user on one node, and and the same user
does not exist (uid = -1) on the other node.

Now you have three options in principle to fix that:

1. use a domain and make your samba server a member.
   this removes the need of maintaining local users in the
   cluster.
   This is the most common mode by far.

2. use an external user database: ldap
   this can definitely be done. Setup is like for a
   non-clustered server.

3. establish a mechanism that keeps the unix users and
   groups in sync on the nodes. (i.e. including uids/gids).
   This needs to be done on creation time. So concurrent
   creations on different nodes don't creat conflicts.
   I have never set up something like that and I have never
   heard of such a setup either.

I hope this helps.

Cheers - Michael

[Samba] samba over nfs mount and free space problem

[Alex Mestiashvili]

Hi All,

I see a strange behavior with samba server and nfs mounts.

We have a number of shares mounted via nfs on the smabaserver.

When I connect from apple mac computers to a samba share which is an nfs
mountpoint, the free space of the share is reported as zero.
And obviously Finder is not able to copy anything to the share because
it thinks that there is no free space left.
But copy from the terminal works fine!

In case when samba share is a local filesystem everything works just fine.

I tried "max disk size" option, but is didn't work for NFS, but worked
for a local filesystem.
Didn't work means that available space was reported as zero and I
couldn't copy file to the share.
That's why I think that the problem is somehow samba related and not the
apple software.

"dfree command" also didn't help.

Why there is a difference between the way free space is calculated
between nfs and local filesystems ?
And what else can I try to workaround this problem ?

here is the output of smbd -b
http://www.biotec.tu-dresden.de/~alex/smb_build_options.txt

Thank you in advance,
Alex

I would use a dfs link inside your share instead.

Hi, 

Did you try, 

1) login on the pc.
2) remove the profile from the network. 
3) logout en reboot te computer. 
4) and login again.

Does this work ?

Hi all,

does nobody have the same requirements regarding the dynamic DNS updates ?

I know this setup would somehow circumvent the security efforts behind
the kerberos stuff, but I personally prefer to have security at L2, with
for example 802.1X, and allow the DHCP srver to update name records in
the DNS database.

kind regards

Andreas
