[Samba] Samba, and NFS. lag?
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Afternoon! I have a samba server, which shares out an NFS mounted share. It seems that everything works rather well, except that i get some lag when modifying a file. If i share a directory which is local to the samba server, no lag, everything works perfectly. However, when i share an NFS mounted volume, i get about 30 seconds of lag while writing a file after it's been modified. In my test, i did the following: - From Windows xp, browse to \\smbserver\share\ browse to a directory which you have permission to write to. open an existing file (in my case, a text file, using Notepad). Add a line to the file. save the file. Notepad hangs for about 30 seconds, and then successfully completes its write. The only thin special about this windows XP client is that it has the Novell mobile client installed. I ran into an issue where windows was first trying to access my smb server using novell's ncp, but this was corrected by moving around the provider order in Windows networking. Any suggestions? Anything i can check? Am i perhaps looking an an NFS performance issue? I'm able to modify files over the nfs mount from the smb server without an issue.

We strongly advise against re-exporting NFS imports via Samba, this is asking for trouble on many fronts. You're seeing one symptom of this. It might be the NetApp box, it might also be flaws in the NFS client implementation, who knows. Please enable the CIFS exports directly on the NetApp filer. If for some reason you can't, you might try "posix locking = no" on the samba server.

RE: [Samba] Samba and NFS quota problem
Hello, I don't know if anyone has any ideas on how to solve this. The same issue seems to occur in Red Hat EL 4 as well. CentOS 3.8 seems to be normal with both 23d and built in 3.0.9, so does Fedora Core 6. It seems to be something to do with NFS; though I don't know what's happening. If I change the window size of the NFS mount, although everythings normal on the underlying unix box samba changes the free space on the drive wildly. I don't think it's related to quotas but disk space. This occurs in any samba 3 I try it on. I've put more examples below illustrating what is happening. Does anyone have any ideas?

RE: [Samba] Samba and NFS quota problem
Hi, Just in case someone has any idea on how to solve this, I've done some further testing. I get the same error below on both a fresh CentOS 4.4 install on x86 (not x64, to rule that out) using built-in RHEL packages; and on the original x64 server when compiling from sources (with sys quotas and disk quotas enabled or disabled). As I say I can see the quota correctly on the Samba server using the unix quota command but on the windows client the samba mapped drive shows entirely the wrong value as free/used. If I make the home directory on a local disk which doesn't use quotas all is fine. Am I missing something really obvious?

[Samba] Samba and NFS quota problem
Hello, I am mounting via NFS a number of volumes and re-sharing these as CIFS. We have been using this arrangement successfully for a number of years. We are replacing the "CIFS>NFS" proxy servers (which are also PDC/BDCs to OpenLDAP) and a weird problem seems to occur. The problem is the quota/disk size appears to be wrong. For example, if I use the unix quota command on the SMB server, it shows correctly the quota and usage. However on the windows machine this is showing incorrectly. The NFS is mounted with no special options, and I have tried against different NFS servers, different Samba versions and can replicate the problem on both the PDC and BDC servers (which are setup identically) OS: CentOS 4.4 x64 Hardware: Dell Poweredge 2950 Current Samba version: samba3-client-3.0.23d-30 samba3-3.0.23d-30 (Also occurs on CentOS/RHEL Samba-3.0.10) NFS server: Solaris 9, default settings. Also it shows the wrong quota information using another NFS server (EMC Celerra NAS 5.5) Quota shows correctly using quota command: Filesystem blocks quota limit grace files quota limit grace helios:/adm/d501 359519 50 500500 668 0 0 Disk usage on the windows system shows: 8.98MB free of 265MB - writing any file to this fails. Samba also appears to be compiled with quota options enabled: # smbd -b| grep QUOTA HAVE_SYS_QUOTA_H HAVE_LINUX_XFS_QUOTAS HAVE_QUOTACTL_LINUX HAVE_SYS_QUOTAS HAVE_XFS_QUOTAS WITH_QUOTAS WITH_QUOTAS Any thoughts on this problem would be greatly appreciated. I am about to compile from source to see if this still occurs.

[Samba] Samba and NFS file access problem.
Hi, I've got samba 3.0.14a server and on the same machine is nfs server. Some files are share for Windows and Linux clients. The problme is when two clients one from win other from Linux try to open the same file. If Linux user first open file Samba user can open it (i/o error), in oposite situation Linux user can open the file to rw (!?) - the same file is edited by both - when win try to save error occurs. Is there any solution for this situation. I've tried turn off oplocks - didn't help, i've looked almost evereywhere and can't find soulution. If it possible that if samba user open file it will open readonly for nfs user and if nfs user opens file samba user will open if ro. Thanks for any help!

For example, if you were access files via NFS, you might see something like this client -> NFS -> NFS server and for samba client -> SMB (CIFS) -> Samba server However, in your example, client -> SMB (CIFS) -> Samba server -> NFS -> NFS server The client has to go through two network file systems to get to the data. Not really much of a slowdown. I have that confirugation setup within my own network with roughly 25 users. Primarily, they are accessing Samba from the server hosting the files, however if need be those Samba shares can be accessed via NFS then Samba off the second Server. I configured the two servers 'identically' with the second server running an rsyne between the 'share' and a 'share2' over NFS, that way if the primary server fails, all I need to do is change umount 'share2' and remount it as 'share' and voila no other changes are necesary, since the same fileshares are already available through Samba via both servers. If I wanted to, I could quickly edit the smb.conf file to change the 'server' name the second server broadcasts and within a few minutes everyone will be 'reconnected' to the 'original' server. In my tests, there really is very little difference in performance. -Rob -- To unsubscribe from this list go to the following URL and read the instructions: http://lists.samba.org/mailman/listinfo/samba

Re: [Samba] SAMBA and NFS
Thank you for the response. Would there still be a performance problem if I had two NICs in the PC? One to connect to the NFS share and the second NIC to connect to the windows PCs? I am talking about a maximum of 20 people connecting to the samba share with at most 5-6 people passing data over the share. The samba server would be a 2.2GHz PC with 512MB of RAM.

[Samba] SAMBA and NFS
Can samba connect to an NFS share and then re-export that share so my windows XP users can connect to it? Basically I have a NFS share that all of my windows XP users need read-only access to. The goal of this project is to replace an old MS Gateway Services for Novell server (using IPX) with something that can do the same thing but over IP. I am pretty sure Novell and AD can share files using Native File Access, but that would require the Novell admins to get CIFS setup on the Novell side. The Novell server we are using has NFS already setup and getting that much setup was like pulling teeth. Thanks, BOFH1234 _ Is your PC infected?
