<p class="MsoNormal"><span lang="EN-GB">Hi team<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">I have a special case here: I am trying to create a glusterFS volume from NFS mounts offered by third party.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">But it fails. The long story has as follows:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">I have two 50 GB NFS volumes offered from two data centres:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">In DC1:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">sbox1.mydomain:/q_files<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">IN DC2:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">sbox2.mydomain:/q_files<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">I dont have even ssh access to those sboxes so I cannot install or do anything, but I am allowed to mount their directories with r/w over tcp.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">I have setup a pair of VM nodes running glusterFs. One node on DC1, one on DC2.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">On each of MY nodes, I mount the offered NFS partitions:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">The node in DC1 mybox1.mydomain.corp mounts the partition from DC1 machine:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">mount -t nfs sbox1.mydomain:/q_files /nfs<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">The node in DC2 mybox2.mydomain.corp mounts the partition from DC2 machine:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">mount -t nfs sbox2.mydomain:/q_files /nfs<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">I do the peering normally…<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">root@ mybox1:~ # gluster peer probe mybox2.mydomain<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">peer probe: success. Host mybox2.mydomain port 24007 already in peer list<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">ok so far – no problem.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Then I try to create a glusterFS volume from those mounts:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">root@ mybox1:~ # gluster volume create mynfs replica 2 mybox1.mydomain:/nfs mybox2.mydomain:/nfs force<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">volume create: contentstore_nfs: failed: Glusterfs is not supported on brick: mybox1.mydomain:/nfs.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Setting extended attributes failed, reason: Operation not supported.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">I get this message: Operation not supported.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">The question is obvious:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Does GlusterFS supports such an operation? In other words, can I create a glusterFS volume from bricks created from NFS mounts?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">If it is feasible, can you please specify what am I doing wrong?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Best Regards<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">mike<o:p></o:p></span></p>
