Symptoms

1) Install Oracle Grid Infrastructure 11.2.0.1.0 on Linux. Processor architecture (x86, x86-64) is irrelevant. Make sure 'Cluster Installation', not 'Standalone' is selected during installation. For the sake of clarity, let us assume that the OS user who invoked runInstaller, is called grid. Unless explicitly specified, all other actions are made with this OS user rights.

2) Configure ASM whatever way necessary. Create a single diskgroup called DATA.

3) Ensure that diskgroup's attirbute 'compatible.asm' is set to '11.2' (run in sqlplus):

4) Create a single acfs volume called TESTVOL:

5) Format the future filesystem (you'll need to check exact device name):

6) Create CRS resource for the future filesystem:

7) Create the mountpoint (root privileges are possibly needed):

8) Mount acfs filesystem:

Sample Output:

9) Observe mountpoint permissions:

Sample Output:

10) Change mountpoint permissions (root privileges again):

Sample Output:

11) Remount filesystem:

Sample Output:

12) Observe mountpoint permissions again:

Notice that it is reset to 770.

Sample Output:

13) Unmount the filesystem:

Sample Output:

14) Mount the filesystem again, but manually this time (root privileges):

Sample Output:

15) Change filesystem permissions and remount (root privileges):

Sample Output:

16) Observe mountpoint permissions and notice that they persist across remount:
