[Samba] 3.0.22 becomes non-responsive
We have a samba 3.0.22 server which acts as file storage for our mail system (Mercury/32 Pegasus Mail), serving about 600 users, with a typical load of 150 concurrent users. We have been seeing an increase in stability problems such as: 1. shared win32 executable files become locked to the point where the win2k client reports the file is corrupt, or access is denied. Clients have read-only access to the share where the files reside 2. a client cannot browse shares on the server from a win2k client, or the browsing is extremely slow 3. in one instance today, while browsing a share, the client was presented with the contents of a *different* share. Investigating cases #2 and #3 usually shows that clients having connection problems have excessive numbers of smbd processes running for them, up to 10. In some cases, killing processes for the affected stations will resolve the problems, and even free up the broken executables in #1. However, once a week or so, we have to resort to restarting the samba processes entirely, as the problem processes don't respond to a kill. When things are running smoothly, the server sees about 20-30% CPU usage by the smbd processes (total), and a load average of 0.5 to 1 System has 512Mb RAM, and doesn't appear to be running out - swap is not used significantly. Redhat 8.0XFS installer version, kernel 2.4.18-18 from SGI. I am seeing some 'kernel: lease timed out' messages, but they don't seem to coincide with the problems we are seeing - two of them yesterday in the log, but we've have far more than two issues with samba in the past 24 hours. Below is the smb.conf Thanks for any assistance. ps: This machine is slated for replacement, with a new server already running, but we have no time to do the swap right now, so hope to stabilize samba for a few more weeks.

[Samba] Name mangling problem
We have a few applications which are still 16bit (running on Win2k clients), and since moving some user data from NT4 to Samba, users have encountered the unpredictable filename mangling issue, where New Folder appears as NUJRHW~7. Users use 8.3 filenames when working in these programs, but often have folders with long filenames that are now unrecognizable. Is there any workaround for this, aside from renaming all the folders? -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Shawn Wright, I.T.

[Samba] Problem with ACLs after upgrade to 3.02
I'm trying to work out an upgrade path for upgrading our 2.2.8a servers to 3.x, and have run into the following problem. (surely someone has documented this?!) Freshly loaded Mandrake 9.2 server using XFS with ACL support. Samba 3.0.2a compiled with: --with-winbind --with-acl-support --with-quotas The stock 2.2.8a Mandrake RPMS were installed and tested first. Then the binaries from 3.0.2a were copied over. After adjusting for different conf and var locations, 3.0.2a starts successfully, and testparm shows the smb.conf to be ok. Re- joining the domain using net join worked fine. Can connect as domain admin to a share to which domain admins are designated admin user. I can successfully edit existing permissions for user,group,other from Win2K. But any operations (from win2k client) which attempt to add an ACL for a domain user or group to a file fail with 'access denied'. In addition, attempting to add permissions for a local unix user or group show an empty list - just everyone. The above operations work on 2.2.8a using the same config, with the exception of the recursive permissions problem I reported earlier (to which nobody responded, making me wonder if anyone else actually uses ACLs for domain accounts on samba...). Here's the conf file: [global] hosts allow = 10. 139.142.66. 127. winbind uid = 1-2 max xmit = 65535 allow hosts = 139.142.66. 10. dns proxy = no netbios name = PROXY4 oplocks = yes inherit permissions = yes workgroup = SHAWNIGAN debug level = 3 security = domain getwd cache = yes winbind separator = + log level = 10 read raw = yes write raw = yes socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=16384 SO_SNDBUF=16384 wins server = 139.142.66.1 create mask = 0700 domain master = no map to guest = never null passwords = no encrypt passwords = yes template shell = /bin/false dead time = 0 password level = 0 server string = Proxy Server password server = * winbind enum users = yes winbind gid = 1-2 unix password sync = no winbind enum groups = yes directory mask = 0700 preferred master = no [home] comment = Homes browseable = yes writable = yes available = yes public = no only user = no path=/home valid users = @shawnigan+domain admins admin users = @shawnigan+domain admins [sysroot] comment = sysroot valid users = @shawnigan+domain admins admin users = @shawnigan+domain admins writeable = yes path = / allow hosts = 139.142.66. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Shawn Wright, I.T.

[Samba] Samba tuning for Linux?
We encountered a stability issue last week on one of 2.2.8 servers running on RedHat 7.1 (2.4.19-13 kernel with SGI XFS patches). It appears we exceeded the max files and kernel setting, which resulted in having more than 300 zombie smbd processes that we could not kill without a reboot. Increasing the value of 'file-max' in /proc/sys/fs from the default of 8192 to 32768 seems to have cured the problem for now. But I'd like to know if there are some guidelines for tuning samba and linux for stability and performance. I've applied most of the tips for Samba I think, but am not certain about the linux config. How many of you are running Samba 2.2.8 on Linux with 300+ concurrent users? What kinds of changes have you made to improve stability? Thanks. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Shawn Wright, I.T.

Re: [Samba] Some final notes: Backup Exec Samba shares
Interesting... Sorry if I missed the previous thread, but had you considered using the free BE agent for *nix? We've been using it for several years on 3 production samba boxes and BE8.6 running on an NT server. Speed is much slower than the Veritas agents on NT, and a bit slower than non-agent backups from NT, bit it works. We are currently backing up ~50Gb from Samba using the agent. btw - I agree with your assessment of Veritas - after 6+ years with BE, I suspect our next upgrade will be to another vendor. We bought 9.x last summer, and wasted 2 weeks trying to get it working, and finally gave up and went back to 8.6. All the while, Veritas support was hopeless. I don't think they even tested v9 on an NT server, as 3 of our servers were clean OS installs and they wouldn't even install BE9! When 8.6 no longer supports our hardware (the only reason we went from v6 to v8), then we'll look elsewhere, unless Veritas changes their MS-centric focus. Their requirement for IE on the server just to run BE9.x was the last straw!

Between his comments and my direct experience, I've only found ONE combination that will work, and that is: NetBSD 1.6, Samba 2.2.8a, and Backup Exec 8.6. If you take NetBSD up to 1.6.1, everything stops working and you can no longer browse the Samba shares. I suspect you could change Backup Exec to 9.x, and Samba to 3.x, since I had the same symptoms in either condition, but I did not try it (ran out of time). With that said: I have discovered that CA's ARCServe package (formerly made by Cheyenne Software) couldn't care less if a network share is sourced by a Windows or *nix type system running Samba. It browses and backs up either one with ease. Chris already posted the same thing he mailed to me to the list. Essentially, Veritas won't do a thing about it, and it does appear to be a design flaw in their software (considering that ARCserve doesn't have a problem with it). Sad, really. Backup Exec used to be a pretty good product.

[Samba] Upgrading 2.2.8 - 3.0 howto, pitfalls?
We have two production servers running Samba 2.2.8 on Redhat 7.x using XFS filesystem with ACL and quota support. Although it has been working ok for nearly two years, we still see strange ACL behaviours, and occasionally what appears to be winbindd idmap corruption. PDC is NT4, and samba servers are domain members only. We're also seeing lackluster performance at times, possibly due to the number of concurrent users, typically 100, but peaks of 300. I'm hopeful that 3.x might address some of these issues, but am concerned with transition problems on heavily used servers. Specifically, where can I find answers for: 1. Is the winbindd idmap unix-domain mapping table migrated smoothly? 2. Are the memory requirements similar to 2.2.8? (we're running 512Mb, which seems to be just barely enough for 2.2.8). 3. If things go wrong, can I just restore the idmap and 2.2.8 files and go back?

Is this feasible (remember smbd runs as root... )? Has somebody thought about implementing this ? If you have Full Control over a directory (e.g. as root, or own it or have rwx on it), you can give FC (rwx) to others. Is it perhaps the other way around, that you want to stop this delegation, unless an FC EA explicitely allows it? I'm not sure if it can be a show-stopper or if it really makes a difference. In our case, the only users who require Full Control access are admins, so we use admin users = @domain/domain admins. Not ideal, but it gives us the NT equivalence we require, and has allowed us to migrate a large portion of our file storage to Samba. We find the option nt acl support = no to be a nice feature that is not available on NT. It prevents our students from messing with ACLs (for their own files) which had been a problem on NT. We provide a second admin access only share which provides ACL support for admins. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Shawn Wright, I.T.

[Samba] Problem with xcopy /d samba
A problem has arisen with the way samba handles file creation dates compared to NT/win2k, which prevents xcopy /d from working correctly. On NT/Win2k, files copied from another NT machine using xcopy end up with the modified dates equal to the original modified date of the file, and the created and accessed dates become the date of the xcopy operation. On Samba, files copied from an NT machine using xcopy end up with created modified dates equal to the original modified date of the file, and the accessed date becomes the date of the xcopy operation. Dates are as reported from a windows NT client in both cases. The problem is that xcopy /d will NOT work as expected when attempting to use it to only copy newer files from NT to samba. Instead XCOPY /D will copy *all* files. This is a problem as we hope to migrate a large # of files from NT to samba and minimize downtime by using xcopy /d to refresh any modified files. In this case we will use a tape backup/restore to handle the modified files, but it would be nice to know if xcopy can be made to work with samba in this way? -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Shawn Wright, Systems Manager Shawnigan Lake School http://www.sls.bc.ca [EMAIL PROTECTED] -- To unsubscribe from this list go to the following URL and read the instructions: http://lists.samba.org/mailman/listinfo/samba

[Samba] Re: Winbind broken after 2.2.8 upgrade
Ok, stupid me. Somehow I missed updating /lib/libnss_winbind.so on both these machines. Presumably this would have also caused corruption of the winbind idmap? Since winbind is now installed with a make install, would it not be a good idea to also install libnss_winbind.so also? Or at least provide some version checking in winbind so that it will fail to start and report an error if it encounters the wrong version of libnss_winbind.so? It seems that the idmap file is a very weak link in samba right now, so every effort should be made to prevent corruption during upgrades, etc. In our case, I was able to re-apply acls for 400 users, but quota information for a large shared file volume was lost, as I could not re-map the ids, and had to reset file ownerships to avoid users having incorrect quota assignments.

[Samba] Duplicate winbind uid/gid
We've encountered the following problem on our Redhat 7.2/XFS box running samba 2.2.3 with winbind and acl support. This week, some local accounts were created on the samba box for the installation of djb's dnscache. In addition, some NT domain accounts were also created on the NT4 PDC. The samba box is configured to use the NT4 domain for authentication; none of the local accounts are used for samba. In checking, I can see that one of the local accounts I created was assigned the same uid as that assigned by winbind for one of the new domain accounts! I have the following in smb.conf, which I thought was meant to avoid such collisions, but it appears that adduser used what it thought was the next available uid, as did winbindd... [global] winbind separator = + winbind uid = 1-2 winbind gid = 1-2 winbind enum users = yes winbind enum groups = yes Adding local accounts is not something done very often, but I would like to prevent this occurrence in the future, and fix the collision I now have.

Re: [Samba] Which filesystem to increase Samba performances ?
I have been gradually moving our user storage from NT servers to RH Linux servers over the past two years, and have found the following based on our very specific needs: SGI's XFS filesystem on RedHat 7.x has been a stable platform since going into production on a machine serving 400 students last year. It is running fairly modest hardware (P3/500, non-raid UW-SCSI disks) but is able to keep up with much faster NT machines quite well, even when dealing with over 100 concurrent users. Last summer, when it came time for another server migration, I looked into EXT3 as an alternative to XFS and encountered the following: Performance with EXT3 was below that of XFS 1.1 in nearly every case, often by more than 15%. Tests were by no means scientific, but consisting of repeated cycles of file reading writing to/from NT clients. Times were measured multiple iterations with file sizes of 8K, 50K, 1Mb and 10Mb. If EXT3 had other redeeming qualities, I could have overlooked the performance issues, but it didn't: -quotas: this is something we *need* and they work nicely in XFS, but I had no success getting them to work with EXT3 on Redhat 7.3 -ACLs: this is another thing we *need*, and the situation was very similar to quotas - I had no luck getting them going. I ended up leaving the new machine with the XFS 1.1 installer version of Redhat, since I could not afford the time to get quotas and ACLs going on EXT3. Keep in mind, all the above is very specific to our environment, where flexible security (ACLs), quotas, performance, and stability are all critically important factors.
