hi All, We have a glusterfs cluster with 5 nodes on Ubuntu 12.04 amd64. We use this smb.conf: [global] socket options = IPTOS_THROUGHPUT TCP_NODELAY IPTOS_LOWDELAY SO_SNDBUF=131072 SO_RCVBUF=131072 read raw = yes server string = %h write raw = yes #oplocks = yes max xmit = 131072 dead time = 15 getwd cache = yes use sendfile=yes block size = 131072 load printers = no aio read size

Dear all, After 4 days of sleepless nights, I have manged to rebuild the samba farm. I believe the following discovery might interest our samba community. ------------------------------------------------ System setting: I have deployed samba 4.1.0 system for my working organisation. It comprised of 2 DCs and 1 member server. 2 DCs maintains AD for login and the member server host files for

Hi, I have installed Xen on Linux 2.6.11.10 <http://2.6.11.10> and i am trying to do Asynchronous Direct IO on SAS drives. The application which does the asynchronous direct io on SAS drive is running on Domain 0. Actually the IOPs what i get for a 512Bytes IO size is 67, but if i do the same operation on Linux 2.6.11.10 <http://2.6.11.10> native kernel, i get 267 IOPs.Cananyone

I have spent most of the past 24 hours reading various samba docs and searching google for help -- but can't find a solution. Suggestions and solutions would be appreciated. I have set up a Linux Box (Samba 3.02) as a PDC with roaming profiles. (I haven't upgraded, because this box is a model for over 100 other boxes in the field). I can add XP users to the domain and their roaming

The long term plan is to get all of Dovecot disk I/O asynchronous. The first step to that direction would be to make dbox/mdbox I/O asynchronous. This might also allow mbox/maildir to become partially asynchronous. http://www.dovecot.org/list/dovecot/2009-December/045481.html already started describing how the lib-storage API could be changed to support high-latency storages. Adding support for

Hi, I am trying to optimize my gigabit network. I have two Intel 1000 MT Gigabit Server Adapters, which support Jumbo Frames -- as well as a Switch that supports Jumbo Frames. However, I am observing some strange behavior in my file transfers from Windows XP to Linux and I am wondering if it has anything to do with the way the Samba variables are set on my Linux box? The "strange

Do anyone have any experience using 10 Gigabit Ethernet connections with Samba? Specifically, if you have had such an experience, can you share what sorts of optimizations you made to get the maximum data transfer between server and workstation? I am just experimenting with this kind of setup myself and I see a huge GULF between the raw TCP/IP transfers that I can make between two

Can anybody explain why SOME Windows XP applications have trouble writing files larger than 2 GB (or sometimes larger than 4 GB) to Linux Samba shares, when OTHER Windows applications on the same machine do not have difficulty writing large files to the same Samba share? And when the underlying Linux filesystem supports very large files? I have sometimes even found that a SINGLE Windows

Hi, Is there a simple way to set up Samba so that users ONLY see the shares that belong to them? I'm not talking about the user's HOME directory. But lets say I have 60 shares in my smb.conf file. To make it less confusing for users when they access the Samba server from Windows, I want the users to ONLY see the shares that belong to them. So, I want to set up each share so that

Can somebody tell me how to get samba to ask me for a username and password when I click on my Samba server in Windows XP Explorer? When I click on another computer on the network (Workstation A) from a workstation (Workstation B) where I'm NOT logged in with a username:password that Workstation A recognizes as having an account, I get a dialog box asking me for a username and password.

Hi, I have a weird problem with a Linux Server acting as a PDC with Samba 3.02. If I map a particular Samba share as the "Z" drive -- and I use roaming profiles with a logon.bat script -- the share will NEVER automatically reconnect when logging on again. This happens 100 percent of the time. And now the same thing seems to be happening for any shared mapped as the

I have Samba 3.0.0 installed on Mandrake 9.2. I also have Samba 2.8.8a installed per instructions from Mandrake -- but I do NOT start Samba 2.8.8a automatically. In fact, I don't use it at all. Maybe I should uninstall the Samba 2.8.8a rpm??? I will update to 3.0.1 as soon as an rpm is available from Mandrake. Anyway, I have a problem when I try to add a new share to my smb.conf file. I

Does somebody know if the Samba Client in MAC OS X (10.3.4 and 10.3.5) has problems looking at Linux-based Samba shares that are larger than 2 TB? I have Samba 3.0.2 running on my Linux box. I have never had any difficulty with the Mac seeing a 2 TB RAID array on the Linux box, but when the Mac looks at the 4 TB array, it can see all the contents and create folders but it can't create

Hi, I'm setting up a Linux machine to use as a file server for a small group of windows machines. Like many of the folks who write to this list, I'm having all kinds of difficults getting the Windows machines to be able to access the Linux shares. In my case, the most frustrating thing is that all of my Windows machines and users can access the Linux shares SOMETIMES. But

Hi, Does anybody know why Windows clients can see shares that are defined by the "include=/etc/samba/smb.%U.conf" option in but Mac OS X and Linux Samba clients cannot see those shares? In other words, I have a bunch of users. Each user has a set of his/her own unique shares on my Linux server that are defined in files called: /etc/samba/smb.User1.conf /etc/samba/smb.User2.conf

Hi list, I have this problem of (relatively) poor samba read performance. Read performance is constantly, reproducibly lower than write performance and I can't really understand why. Here is the server configuration : dual octocore Opteron 6128, 32 GB RAM Adaptec 6445 RAID card 36x 2TB Hitachi SATA drives (raid 60) Sustained local disk throughput: over 850 MB/s write, over 1.4 GB/s read.

I've just reconfigured my Samba 3 setup so that Windows users basically only see shares they are supposed to see when they browse the Samba server through Explorer. At the suggestion of others on this list, I used the "include = /etc/samba/smb.%U.conf" feature and create a "smb.username.conf" file for each Linux user. To get Explorer to display the shares assigned to

Hi Samba list. Here is my scenario. I have 10 Windows XP machines that use a Linux box as a file server. Running Mandrake 10 (more or less), 2.6, Samba 3.03. We have hundreds of individual shares defined -- but users only see their own shares (we use the "include=smb.%U.conf" setting in Global settings, and define the shares in individual conf files for each user.) When we use
