Whiteboard:
Fixed In Version: glusterfs-3.4.0.18rhs-1 Doc Type: Known Issue
Doc Text:
Cause: On the gluster volume, ACL setting doesn't work as expected due to the caching of metadata in client side. Consequence: the ACL setting with 'setfacl' is not visible from 'getfacl' command. Workaround (if any): disable 'stat-prefetch' (or md-cache) translator by 'gluster volume set <VOL> stat-prefetch disable'. Result: After disabling the 'stat-prefetch', ACLs works fine on gluster mount.

Description Anush Shetty 2013-07-29 09:20:16 UTC 
Description of problem: Setting ACL entries to files on RHS fails.


Version-Release number of selected component (if applicable): glusterfs-3.4.0.12rhs


How reproducible: Consistenly 


Steps to Reproduce:
1. Create a 2x2 Distributed-Replicate volume

2. Mount RHS client
   mount -t glusterfs -o acl 10.70.37.49:acl /mnt/gluster

3. Create file on mount point and set ACL entries on the file
   
   # touch file1

   [root@rhs3 gluster]# ls
   file1

   [root@rhs3 gluster]# getfacl file1
   # file: file1
   # owner: root
   # group: root
   user::rw-
   group::r--
   other::r--

   [root@rhs3 gluster]# setfacl -m u:test:r-- file1

   [root@rhs3 gluster]# getfacl file1
   # file: file1
   # owner: root
   # group: root
   user::rw-
   group::r--
   other::r--



Actual results:

Setfacl command fails to set acl entries.


Expected results:

This is a regression. Setting ACL entries should succeed.

Comment 6 Amar Tumballi 2013-07-29 17:26:43 UTC 
Can you confirm if doing 'gluster volume set <VOL> stat-prefetch off' and doing the same operations fixes the problem?

Next question is, if there is a work around, is it a blocker?

It is not really about setting stat-prefetch off. But after any graph change, I see that setting ACLs work.
Comment 8 Amar Tumballi 2013-07-30 11:47:35 UTC 
If you disable 'stat-prefetch', no more graph changes are required. We are working on a fix for this. But till that time, (for all ACL tests) can you proceed with stat-prefetch disabled.
