Samba: smb_add_request: request timed out!

I agree, I've got the same problem going on on my FC3 2.6.11-1.35_FC3smp.

Hello,

I encounter exactly the same problem yesteraday with a RH EL3.

Samba freeze each time a user try to write de file to a drive.

After a pretty long search and few tests, i found the smb daemon was absolutely not in fault. The problems comes from another smb mount on the computer (mounted as a client, not used by smb daemon). Unmounting the share was enough to solve me problem.
Nowhere is the log i can get a clear information about the problem (only the error reported in this thread) and regenerating cache/ restarting smb daemon has no effect.
A reboot should have probably fixed the problem but unmount/mount all the smb mapping might help you to.

About 4h of intensive search anyway....

I am still suffering from this error. could that be?

Glad to see that others are seeing this as well...I'm going to look back into this issue over the weekend to see if I can find out any additional logs or clues as to why this might be happening.

Post more later...

I have same problem.

client, smbfs, using Smb4K to connect:

Code:

smb_add_request: request [c2f1ed80, mid=14885] timed out!

xmms does not stop playing but konqueror file browser hangs. It becomes all white for some time and I can still seek xmms song wherever I want(It can read!)
Sometime konqueror does not recover and then xmms hangs too.

some more errors on client side I have lots of them:

Code:

kernel: smb_writepage_sync: failed write, wsize=1024, write_ret=-5
kernel: smb_writepage_sync: failed write, wsize=4096, write_ret=-512
kernel: smb_file_write: somefile.tar validation failed, error=4294967291

There is no errors on server side.

well i finally tried the windows way of doing it:

The two basic principles of Windows system administration:

* For minor problems, reboot
* For major problems, reinstall

But as this is linux I what a real answer to this problem.

I sent this thread to the Samba team and got a reply:

That's a smbfs problem. smbfs is unmaintained and about to
be removed from the kernel. You might want to try cifsfs.

thats bad. I have owner/group problems with cifsfs.
from server side:

Code:

-rw-r--r-- 1 1000 1000     2923 2006-08-31 01:03 test.txt
-rw-r--r--  1 userx userx     2923 2006-08-31 01:03 test.txt

that user and group id (1000) is used on clients too. By default first user gets that id on most my systems whatever his/her username is. When I log on there comes problem with permissions and possibly security threat.
but thats other story

saavik · 10-27-2006, 01:40 AM

does that mean i can forget my:

smbmount //servername/share-name /target-dir -o username=bob,uid=root

????

And use

mount -cifs //servername/share-name /target-dir -o username=bob,uid=root

Did I read that right?

Can somebody give me a technical doku, as I would like to get an answer to the following questions:
- Why is smbfs unsupported ?
- Whats the difference between smbfs an cifs ?

OK: http://linux-cifs.samba.org/

I'm having exactly the same problems with cifs mounts; but only when I mount to another Linux/Samba server. When I connect to a Windows 2000 box everything seems to work perfectly.

The mount command looks like this:

Quote:

mount -t cifs -o user=Administrator,uid=LOCALUSERID,gid=LOCALGROUPID //SERVER/SHARENAME DIR/SHARENAME

As you can see I use the options uid & gid to specify which local user/group is owner of the files in the mount, but this does not work with mounts to a Linux/Samba server; I get 'strange' uid and gid instead.

Is there a mount.cifs option to get rid of this owner/group problem?

thelinuxdude · 07-18-2007, 04:33 PM

Recently, I posted a patch to the lists.samba.org for a patch to fix smbfs to work like it does in 2.4. This patch allows your system to recover after smb times out due to a lost connection.

The patch is based on the original smbfs in 2.4

Since smbfs is being removed, I suggest using CIFS. We don't because of the following reasons:

1. netbios name resolver does not work when using mount.cifs.
2. if the ip address changes on the server due to dhcp, CIFS does not reconnect if using an ip address (you have to use an ip address if you can only resolve by netbios name).

You should be able to find the patch on the samba mailing list.
