Solution 2248316.1 : Oracle ZFS Storage Appliance: Unable to Change Ownership on a file even if the Restrict Ownership Change is Unchecked

Applies to:

Oracle ZFS Storage ZS5-4 - Version All Versions and later
Oracle ZFS Storage ZS5-2 - Version All Versions and later
Oracle ZFS Storage ZS4-4 - Version All Versions and later
Oracle ZFS Storage ZS3-4 - Version All Versions and later
Oracle ZFS Storage ZS3-2 - Version All Versions and later
7000 Appliance OS (Fishworks)

Symptoms

OVMs with Oracle Solaris 11.2 and Oracle Solaris 11.3.

Error received when owner tries to change the ownership of files even if the restrict ownership change property is not selected in project.

Oracle@lbl-266:~/test$ ls -la
total 7
drwxr-xr-x 2 oracle dba 3 Mar 14 12:05 .
drwxr-xr-x 3 oracle dba 9 Mar 14 12:03 ..
-rw-r--r-- 1 test dba 0 Mar 14 12:05 file

Error:

oracle@lbl-266:~/test$ chown oracle file
chown: file: Not owner

Cause

By default, NFS shares are mounted in Solaris with the rstchown option, so we are not able to change ownership - even if the project has unselected this property.

Solution

Add file_chown_self to users that need to change file ownership or mount the share with the norstchown option.

To check user attributes:

oracle@lbl-266:~$ ppriv $$
1960: -ksh
flags = <none>
E: basic,file_chown_self
I: basic,file_chown_self
P: basic,file_chown_self
L: all
