Description Saurabh 2013-07-22 13:29:03 UTC

Description of problem:
created a dir 
create a symlink
set quota limit on symlink
and limit crosses

Version-Release number of selected component (if applicable):
[root@nfs1 ~]# rpm -qa | grep glusterfs
glusterfs-3.4.0.12rhs.beta4-1.el6rhs.x86_64
glusterfs-fuse-3.4.0.12rhs.beta4-1.el6rhs.x86_64
glusterfs-server-3.4.0.12rhs.beta4-1.el6rhs.x86_64

How reproducible:
always

Steps to Reproduce:
1. create a volume, start it
2. enable quota on the volume
3. set some limit on quota
4. mount the volume using nfs.
5. create a dir
[root@rhsauto030 nfs-test]# mkdir foo
6. create a link for dir
[root@rhsauto030 nfs-test]# ln -s foo bar

[root@rhsauto030 nfs-test]# ls -l 
total 480
lrwxrwxrwx. 1 root root     3 Jul 22 07:54 bar -> foo
drwxr-xr-x. 2 root root    36 Jul 22 07:53 foo

7. set limit on the symlink,
[root@nfs1 ~]# gluster volume quota quota-dist-rep limit-usage /bar 10MB
hard limit set on /bar

8. create a file of 100MB now after cding in bar,

Actual results:

[root@rhsauto030 bar]# dd if=/dev/zero of=f.1 bs=100MB count=1
1+0 records in
1+0 records out
100000000 bytes (100 MB) copied, 4.6002 s, 21.7 MB/s


Expected results:
symlink should accept the quota policies.

Comment 3 vpshastry 2013-09-04 08:58:44 UTC

Working for me in my setup with the new build v3.4.0qa8. Can you verify?

Comment 4 vpshastry 2013-09-04 09:08:30 UTC

Cause: The update wasn't happening if it was a symlink in the older implementation, which is not the current case.

Comment 5 vpshastry 2013-09-04 10:31:06 UTC

Cause in detail: In the quotad while updating the quota-limit directories, if the path is a symlink, we were not following the symlink to update the directory with the usage. This causes the quota limits to exceed.
