The system versions are:<br><div><br></div>OS: Debian jessie kernel 3.16<br><div><br></div>Gluster: 3.8.0-2 installed from the gluster.org debian repository<br><div><br></div>I have tested the node failure scenario while some clients are running <br>some read/write operations and the setup works as expected. Now I'm <br>trying to test how to replace a faulty drive on this setup, however I'm <br>not able to replace a brick. To test it I have:<br><div><br></div>1: Find the pid of the brick I'd like to 'fail' and kill the process. <br>(tried removing the drive from the host but that would make the whole <br>guest unresponsive)<br><div><br></div>2: Attach a new virtual drive, format and mount it<br><div><br></div>3: Try the gluster volume replace-brick command<br><div><br></div>And I'm getting the following error:<br><div><br></div>gluster volume replace-brick vol_1 glusterserver1:/ext/bricks/brick-1 <br>glusterserver1:/ext/bricks/brick-13 commit force<br>volume replace-brick: failed: Fuse unavailable<br> Replace-brick failed<br><div><br></div>I assume I'm doing something wrong but don't know what exactly. Looking <br>in the documentation I have not found information about brick <br>replacement in distributed-dispersed setups.<br><div><br></div><br>Thanks!<br><div><br></div>Iñaki<br><div><br></div><br><div><br></div>_______________________________________________<br>Gluster-users mailing list<br>Gluster-users@gluster.org<br>http://www.gluster.org/mailman/listinfo/gluster-users</div><div><br></div></div></body></html>
