Hello,
I have cross-posted
this question in the bareos-users mailing list.
Wondering if anyone
has tried this because I am unable to backup data that is
mounted via Gluster Fuse or Gluster NFS. Basically, I have
the Gluster volume mounted on the Bareos Director which also
has the tape changer attached.
Here is some
information about versions:
Bareos version
14.2.2
Gluster version
3.7.2
Scientific Linux
version 6.6
Our Gluster volume
consists of two nodes in distribute only. Here is the
configuration of our volume:
[root@hgluster02 ~]# gluster volume info
Volume Name: export_volume
Type: Distribute
Volume ID: c74cc970-31e2-4924-a244-4c70d958dadb
Status: Started
Number of Bricks: 2
Transport-type: tcp

Brick1: hgluster01:/gluster_data
Brick2: hgluster02:/gluster_data

server.root-squash: on
performance.read-ahead: on
features.quota-deem-statfs: on
diagnostics.brick-log-level: WARNING
When I try to backup
a directory from Gluster Fuse or Gluster NFS mount and I
monitor the network communication I only see data being
pulled from the hgluster01 brick. When the job finishes
Bareos thinks that it completed without error but included
in the messages for the job are lots and lots of permission
denied errors like this:
15-Jul 02:03 ripper.red.dsic.com-fd JobId 613: Cannot
open
"/export/rclough/psdv-2014-archives-2/scan_111.tar.bak":
ERR=Permission denied.
15-Jul 02:03 ripper.red.dsic.com-fd JobId 613: Cannot
open "/export/rclough/psdv-2014-archives-2/run_219.tar.bak":
ERR=Permission denied.
15-Jul 02:03 ripper.red.dsic.com-fd JobId 613: Cannot

ERR=Permission denied.
15-Jul 02:03 ripper.red.dsic.com-fd JobId 613: Cannot
open "/export/rclough/psdv-2014-archives-2/run_220.tar.bak":
ERR=Permission denied.
15-Jul 02:03 ripper.red.dsic.com-fd JobId 613: Cannot
open
"/export/rclough/psdv-2014-archives-2/scan_114.tar.bak":
ERR=Permission denied.
At first I thought
this might be a root-squash problem but, if I try to
read/copy a file using the root user from the Bareos server
that is trying to do the backup, I can read files just fine.
When the job
finishes is reports that it finished "OK -- with warnings"
but, again the log for the job is filled with
"ERR=Permission denied" messages. In my opinion, this job
did not finish OK and should be Failed. Some of the files
from the HGluster02 brick are backed up but all of the ones
with permission errors do not. When I restore the job, all
of the files with permission errors are empty.
Has anyone
successfully used Bareos to backup data from Gluster mounts?
This is an important use case for us because this is the
largest single volume that we have to prepare large amounts
of data to be archived.
Thank you for your time,
