This is a fairly basic question, so I'm hoping the answer is quick and easy. Perhaps there is something fundamental I'm missing, but despite correct permissions, I still cannot write a file to a folder I was granted access to.

I need to be able to write to the folder "logs"

bash-3.00$ ls -na /data/sandbox
total 12
drwxrwsr-x 5 10064 12985 512 Sep 05 15:23 .
drwxrws--- 4 10064 12985 512 Aug 23 08:45 ..
drwxrwsr-x 2 10064 12985 512 Sep 05 14:53 logs

Any attempt fails though

bash-3.00$ touch /data/sandbox/logs/test.txt
touch: 0652-046 Cannot create /data/sandbox/logs/test.txt.

I can, however write to the folder "logs" resides in.
bash-3.00$ touch /data/sandbox/test.txt
bash-3.00$ ls -na /data/sandbox
total 12
drwxrwsr-x 5 10064 12985 512 Sep 05 17:30 .
drwxrws--- 4 10064 12985 512 Aug 23 08:45 ..
drwxrwsr-x 2 10064 12985 512 Sep 05 14:53 logs
-rw-r----- 1 34250 12985 0 Sep 05 17:30 test.txt
The correct group is applied to the folder (12985)
I am in the correct group (12985)

bash-3.00$ id
uid=34250(myid) gid=2000(group2000) groups=12985(LOGGER)

bash-3.00$ ypcat group |grep LOGGER
LOGGER:*:12985:myid,yourid
The disk has plenty of space available.
What gives?

Is the directory, not folder:-), "logs" by any chance NFS mounted? That's one thing that can cause problems like this. A directory can be mounted read-only and that overrides the permissions.

Thanks for the reply.

It appears to be mounted rw
bash-3.00$ mount
node mounted mounted over vfs date options

Is anyone aware of any tools or logs that might help diagnose this on AIX? Are there any tools that report on file access methods or advanced auditing showing exactly which security credential is being violated?

Apparently, the problem has to do with there being a mix of Solaris and AIX in the NFS environment. Changes on AIX to group level permissions on a file residing on a Solaris-based filesystem are not recognized by Solaris.
Why is this?
