2013-05-09T11:30:59Z

Recently we go an issue where the “Server for NIS” service was not starting on Windows 2003 R2, x64. The error code as per the vent logs was: Event ID 8194. We referred to the TechNet document http://technet.microsoft.com/en-us/library/dd316252(v=ws.10).aspx and followed the instruction. But this did not help. We also checked the schema on the DC and it looks good. Even the registry entries for “server for NFS” were correct. With further troubleshooting found that the...(read more)

Running nismap.exe with –y parameter creates a map with “.” instead of “_”

2013-04-19T11:20:08Z

“nismap.exe” does not create the map name as expected when using the –y parameter. Below is an example of the attempt to use nismap.exe with –y to create the map named auto_home_svr_test: C:\temp>nismap.exe create -i 1 -g " " -s localhost -f "C:\Windows\IDMU\nis\nis2ad.log" -y auto_home_svr_test Activity = Creating map = 'auto.home_svr_test'... SUCCESS Creating With further research, it was confirmed that this is a default behaviour of the nismap function...(read more)

RHEL clients displays Anonymous UID and GID in the permission for the files and folder that are shared over NFS v4.1

2013-03-14T15:53:59Z

Consider a scenario where Windows 2012 is hosting shares over NFS v4.1. Adlookup is configured for user and group mapping. RHEL 5.8 is the NFS client which is mounting the NFS shares and then accessing as a mapped user. From the Windows side correct information is displayed on the ownership tab. Also the user who is owning the share is a mapped user. But from the Linux side, we see anonymous UID and GID when we list the permission. Explanation: The NFS server is supposed to return “<user>...(read more)

Inputs on NFS 4.1 mount: While working on a recent scenario on NFS V4.1, we came across some intresting scenarios for mounting the NFS volumes on the Unix NFS clients. In the implementation of V4.1, there are no particular access requirements to virtual directories , but all relative objects have the relevant security checks applied, namely checks using a combination of the object permissions and the share permissions. In this case, the root directory, namely “/” is virtual and...(read more)

Server for NFS (Windows 2008 R2) crashes as soon as the Clients mounts the NFS share

2012-11-14T08:43:04Z

Recently we got an issue where the NFS server ( Windows 2008 R2 was hosting the NFS share) use to bugcheck as soon as the ESX client was mounting the share. We found that the size of the NFS share was approximately 189 GB in size. The share was open to everyone and also was the only NFS export on the machine. Also the NFS and RPC drivers were updated as per the KB articles below: · http://support.microsoft.com/kb/2485543 · http://support.microsoft.com/kb/2662672 We analyzed...(read more)

Unable to run the ‘PAX” command in Windows 7, SUA with a ‘–q’ option

2012-11-08T10:49:41Z

Recently we got an case where the customer was looking for assistance to run PAX command in Windows 7 SUA. Unlike SFU 3.5, the PAX command in windows 7, SUA does not have "-q" option to suppress error message. Hence it was failing. From the man pages we found that using the new parameter "-Q"; the same functionality can be achieved. Though the same may not have been documented on the SUA help files. Running the man page give the below information: -Q Quiet warnings about files being archived...(read more)

How can we control the permission on the files created from Windows NFS client

2012-10-30T12:43:15Z

We do get a lots of issue where the customer reports that “Permission ere not getting inherited on the newly created files and folder on the NFS client side”. This scenario is intended for the scenario where Windows is the NFS client (running “client for NFS”) service. Usually the confusion is that the permission on the newly created files / folders should get inherited from the server to the client. In case on Windows acting as “Server for NFS” we can enable...(read more)

While working on one of the case, the customer reported that he was unable to access symbolic link of a NFS share. The symbolic link was pointing to another directory under the same NFS share. The NFS share was hosted on Windows 2008 R2. While checking the properties of the link, we found that the link was created using the UNC path instead of the absolute path. We suggested the customer to create another symbolic link and in the target field put the absolute path of the directory. For example...(read more)
