Top Forums UNIX for Advanced & Expert Users changing UGO to ACLs on a file Post 302327260 by davchris on Saturday 20th of June 2009 11:24:43 AM
Old 06-20-2009
The purpose is to set vxfs quota on existing files that have no particular ACL set. I have no other way than getting UGO permissions and change them to ACLs for to recalculate the exact quota usage on files for a usergroup, I will have to chgrp the group to which quota is set on ...
I'll try to explain this way :
at the moment I have this directory

drwxrwxr-x user1 grp1 toto -> no particular ACL
containing one of the files :
-rwxrwxr-x user2 grp2 file1 -> no particular ACL

To set the quota for grp1 and grp2 usergroups, I create a group named i.e "global" and set quota on it. I also recursively chown the owner and the "global" group of the files as the quota will be calculated on the "global" group. The old UGO permissions will be changed to ACL on folders and files to maintain the access rights set before.
This way, the files will UGO belong to an user that has unlimited quota, they will belong to the "global" group, and users still be able to access their files through the ACLS.

drwxrwxr-x uluser global toto -> acl set for user1 and grp1
containing one of the files :
-rwxrwxr-x uluser global file1 -> acl set for user2 and grp2
Quota calculated for global group

I'm aware that I will have to crontab a script that recursively propagate the "uluser" and "global" UGO permissions to calculate the quota on new files
