Hi<br>
<br>
We have been trying back-up a glusterfs (v3.1.4) area using<br>
the Tivoli TSM software to an off-site area. The back-up<br>
keeps failing with the following typical error messages<br>
<br>
06/14/2011 22:22:58 ANS1587W I/O error reading file attributes for: /gdata/projects/philex/OAG/<u></u>2011/May16/mdor3km10/<a href="http://coast_den2.in" target="_blank">coast_<u></u>den2.in</a>. errno = 22, Invalid argument<br>
<br>
06/14/2011 22:22:59 ANS4007E Error processing '/gdata/projects/philex/OAG/<u></u>2011/May16/mdor3km07/<a href="http://coast_den2.in" target="_blank">coast_<u></u>den2.in</a>': access to the object is denied<br>
<br>
We originally thought the problem was bad meta-pointer files,<br>
but we still experience the failures after deleting all meta-pointer<br>
files.<br>
<br>
Has anyone else experienced/solved this problem?<br>
<br>

</blockquote></div><br><br clear="all">Hi Pat, Let me get some one from the engineering team to coordinate with you. For now, you can check this:<div><span class="Apple-style-span" style="border-collapse: collapse; font-family: arial, sans-serif; font-size: 13px; "><br>
</span></div><div><meta http-equiv="content-type" content="text/html; charset=utf-8"><span class="Apple-style-span" style="border-collapse: collapse; font-family: arial, sans-serif; font-size: 13px; ">'/gdata/projects/philex/OAG/<u></u>2011/May16/mdor3km07/<a href="http://coast_den2.in/" target="_blank" style="color: rgb(0, 0, 204); ">coast_<u></u>den2.in</a></span><br>
<div>This file must exist on one of the backend disks. See if you can directly read from the backend disks. If it is not a bad backend disk, then it is a GlusterFS issue.</div><div><div><br><div>If you provide us remote access via reverse-ssh / screen or webex, we can quickly narrow down. We don't have a TSM environment in our labs. You can help us validate compatibility. </div>
<div><br></div><div>Also I am not sure if TSM allows scripting. If we can make TSM tools use GlusterFS 3.2 marker APIs, then you can achieve continuous backup functionality (backup data as and when it changes, without crawling the name space). It will significantly improve your backup performance (no more backup windows). Marker APIs can even be invoked via shell scripting using attr tools.</div>
