[Gluster-users] Double counting of quota

Fri Jun 5 23:19:44 UTC 2015

Hi,
I currently have two brick with replica 2 on the same machine, pointing to different disks of a connected SAN.
The volume itself is fine:

# gluster volume info atlas-home-01

Volume Name: atlas-home-01
Type: Replicate
Volume ID: 660db960-31b8-4341-b917-e8b43070148b
Status: Started
Number of Bricks: 1 x 2 = 2
Transport-type: tcp
Bricks:
Brick1: host1:/bricks/atlas/home02/data
Brick2: host2:/bricks/atlas/home01/data
Options Reconfigured:
performance.write-behind-window-size: 4MB
performance.io-thread-count: 32
performance.readdir-ahead: on
server.allow-insecure: on
nfs.disable: true
features.quota: on
features.inode-quota: on

However, when I set a quota on a dir of the volume the size show is twice the physical size of the actual dir:

# gluster volume quota atlas-home-01 list /user1
                  Path                   Hard-limit Soft-limit   Used  Available  Soft-limit exceeded? Hard-limit exceeded?
---------------------------------------------------------------------------------------------------------------------------
/user1                                    4.0GB       80%       3.2GB 853.4MB              No                   No

# du -sh /storage/atlas/home/user1
1.6G    /storage/atlas/home/user1

If I remove one of the bricks the quota shows the correct value.
Is there any double counting in case the bricks are on the same machine?
Also, I see a lot of errors in the logs like the following:

[2015-06-05 21:59:27.450407] E [posix-handle.c:157:posix_make_ancestryfromgfid] 0-atlas-home-01-posix: could not read the link from the gfid handle /bricks/atlas/home01/data/.glusterfs/be/e5/bee5e2b8-c639-4539-a483-96c19cd889eb (No such file or directory)

and also

[2015-06-05 22:52:01.112070] E [marker-quota.c:2363:mq_mark_dirty] 0-atlas-home-01-marker: failed to get inode ctx for /user1/file1

When running rsync I also see the following errors:

[2015-06-05 23:06:22.203968] E [marker-quota.c:2601:mq_remove_contri] 0-atlas-home-01-marker: removexattr trusted.glusterfs.quota.fddf31ba-7f1d-4ba8-a5ad-2ebd6e4030f3.contri failed for /user1/..bashrc.O4kekp: No data available

Those files are the temp files of rsync, I’m not sure why the throw errors in glusterfs.
Any help?
Thanks,

	Alessandro
