Hello Franck, Yes, DFS is fully supported on the current kernels, but there were some problems on earlier kernels. I can't be certain from the information that you may be running into the remote namespace bug where the final target is not located on the domain controller or the server that you are initially pointed at and the kernel tried to use the existing network connection to communicate with the new machine; you may need to upgrade your kernel. 3.2 is not current. I have personally patched an older 2.6 kernel to work with remote namespaces because management was not in favor of upgrading our kernel but if you are not familiar with the technical details of DFS then that is probably not the right path for you so if you can upgrade your kernel. -Bob > Hi, > > We are meeting some issues with DFS referrals when using CIFS for linux. > I don't know much about technical details on DFS, but before studying > further, I would like to know if this feature is even supposed to be > supported by the Linux CIFS client. > > To explain the situation, we have several shares : > > \\filer\main(main entry point) > \\filer\share1(scattered volumes with data) > \\filer\share2 > > if \\filer\main\share1points to \\filer\share1(top level) we manage to > access the share1 content correctly (so DFS mechanism seems to work) > > but if \\filer\main\some\directory\remote\locationpoints to > \\filer\share2\dir1\dir2\inside\locationhere we get stuck. > > The client can have the following behaviours, more or less with no > apparent logic up to now : > * "Object is remote" error > * "No such file or directory" error > * sometimes locked in infinite loop (with the older versions, see > below) > * accesses it, but lists the content of \\filer\share2(top level of > the share) not the content of \\filer\share2\dir1\dir2\inside\locationso > we loose part of the link's path > > With Windows 7 clients, the expected behaviour occurs correctly. > > We use up-to-date debian 6.0.10 & 7.6, and CentOS 6.5 (i.e kernels > 2.6.32 & 3.2.x) with stock cifs-utils package (2:4.5-2, 2:5.5-1) and the > CIFS server is NetApp OnTap 8, with the widelink feature (translation of > linux symlinks) > > If this should be supported, can you provide information of the > parameters to set correctly, or if we have to compile a newer version, > which one ? > > Thank you, > > Franck > -- > To unsubscribe from this list: send the line "unsubscribe linux-cifs" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html > -- To unsubscribe from this list: send the line "unsubscribe linux-cifs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
