mkdir on nfs filesystem not setting the group writable permissions bit

[Scott Hewes]

Does anybody know why the group writable permission bit is not set when using mkdir to create a directory on an NFS filesystem? I have my umask set to 002. Also, the parent directory has group writable permissions set on both the NFS client and NFS server.

Wonder why I am not getting the same problem. My directories get created on the mounts, exactly based on my umask settings.

Are creating the directory on an NFS filesystem?

hi,
see this -

May I ask how you configured your NFS server and NFS client? I am still having this problem. Also, a user other than "nobody" owns the mount point directory and all file and directories there under.

[Ramkumar Devanathan]

Scott,

here is /etc/exports on my nfs server -

# cat /etc/exports
/tmp -rw=scud

Here is the mount command that i'd run to mount this on my nfs client -

# mount mig:/tmp /mig

What other config details would you require?

I believe I may have found the solution to this problem. The NFS server is actually a Consensys Radizone disk array that is running Linux kernel 2.4.6-3smp. Version 2.4.16-7smp of the linux kernel may fix this problem. I have second Raidzone that has version 2.4.16-7smp installed and I do not have this problem with NFS mounts to that server.

My apologies for not making it clear that the NFS server is a Linux box....

[Scott Hewes]

FYI...

The update of the linux kernel to 2.4.16-7smp solved the problem....
