Hi friends and Gurus,
I need to perform a herculean task it may seems strange but now boll is in my court.
here is my task...
one of my user want ACL on root filesytem...yes acl for / filesystem. root is not in lvm. and also we have another filesystem named /ora which is vxfs file system my user want ACL for that also i mean /ora.
doesn't it seem strange..i never did that, but my user is insisting to do that.
its a production box they may give 2 or 3 hours downtime to perform the task
i googled a lot but i found steps to configure acl for files,folders and other filstems but not for root.
i tried the below steps.
[root@linuxnode1 /]# uname -a

verify that the permissions have been set and that the file has an ACL:
ls -l foo
-rwxrw— + 1 winsor staff 0 Oct 3 14:22 foo
but i cant see the '+' symbal for my / filesystem.. while executing the steps i didn't get any errors.
any help is appreciated....Thanks in advance..
Thanks & regards
