Hi,

I have created the following folder under home/cdhar/
mkdir -p /u01/app/oracle/product/11.2.0/db_1

Now I need to change owner of the folder, but when I give the following command

[root@hdk01ytt cdhar]# chown -R gbuora:gbuinst u01
chown: changing ownership of `u01/app/oracle/product/11.2.0/db_1': Operation not permitted

I checked with cat /etc/sysconfig/selinux and SELINUX=disabled.

what could be the issue? Please suggest

thanks,
cdhar

Is the file open? I think this is a running DB.

Also doing a long list may provide some extra information for this thread.

The reason that your change is not permitted is that you are trying to give gbuora:gbuinst access to /home/cdhar/u01, but becuase of the location (/home/cdhar) gbuora:gbuinst does not have permission to the path to get there. If you look at the heirarchy of the permissions:

drwxr-xr-x. 5 root root 4096 Dec 1 2011 home (Only root can create the user's home directory in /home)
drwx------. 30 cdhar cdhar 4096 Dec 1 2011 cdhar (Only the USER cdhar has ANY access to the home directory /home/cdhar)

No one else but the user (and root) can even SEE what is in that folder, so access cannot be given. You would have to change the permissions starting at /home/cdhar in order to grant someone else access.

The permissions would have to look like this:
drwx---r-x. 30 cdhar cdhar 4096 Dec 1 2011 cdhar (This would allow ANYONE access to read and execute anything in your home directory and below

Keep in mind, this is giving other user's access to your HOME DIRECTORY.... not exactly a safe thing to do...

Can you give these 3 reply.

(1) lsattr /home/username
(2) df -Th
(3) ls -ld /home/cdhar/u01
(3)

This
creates the dir path starting at the system root '/', NOT from /home/cdhar ...

hi chrism01

i was just about to post that error

cdhar

as i was reading the thread
the command you gave DID NOT make a folder IN your home folder
the "mkdir" command made this
/u01/app/oracle/product/11.2.0/db_1
( think if it like on Windows )
C:/u01/app/oracle/product/11.2.0/db_1
and you ran the command FROM your NORMAL user home folder
home/cdhar/
( think if it like on Windows )
C:/home/cdhar/

so when you RAN THIS command IN your home folder
there IS no file ,called u01 ,IN your home folder TO have the command ran on
hence the errors

PS. also DO NOT disable SELinux!!!!
( would you turn OFF the AV software,Firewall, and UserAccessAuthentacation on Windows??? - NO !!! )

for testing and FINDING and FIXING error set it to PERMISSIVE
THEN after you have fixed SE errors
set it to ENFORCING

using mkdir -p /path/to/create as a user should have failed anyway due to lack of permissions..... unless cdhar gave his user root permissions....

I missed the -p earlier....

Looks like he's in as root, according to post #1
