very sorry for misunderstanding.</div><div>Before contacting you during last days, we checked all network devices (switch 10GbE, cables, NICs, servers ports, and so on), operating systems version and settings, network bonding configuration, gluster packages versions, tuning profiles, etc. but everything seems to be ok. The first 3 servers (and volume) operated without problem for one year. After we added the new 3 servers we noticed something wrong.</div><div>Fortunately, yesterday you gave me an hand to understand where is (or could be) the problem. </div><div><br></div><div>At this moment, after we re-launched the remove-brick command, it seems that the rebalance is going ahead without errors, but it is only scanning the files.</div><div>May be that during the future data movement some errors could appear.</div><div><br></div><div>For this reason, it could be useful to know how to proceed in case of a new failure: insist with approach n.1 or change the strategy?</div><div>We are thinking to try to complete the running remove-brick procedure and make a decision based on the outcome.</div><div><br></div><div>Question: could we start approach n.2 also after having successfully removed the V1 subvolume?!</div><div><br></div><div>>>> Yes, we can do that. My idea is to use replace-brick command. <br></div><div>We will kill "ONLY" one brick process on s06. We will format this brick. Then use replace-brick command to replace brick of a volume on s05 with this formatted brick.<br></div><div>heal will be triggered and data of the respective volume will be placed on this brick.<br></div><div><br></div><div>Now, we can format the brick which got freed up on s05 and replace the brick which we killed on s06 to s05.<br></div><div>During this process, we have to make sure heal completed before trying any other replace/kill brick. <br></div><div><br></div><div>It is tricky but looks doable. Think about it and try to perform it on your virtual environment first before trying on production.</div><div>-------<br></div><div><br></div><div>If it is still possible, could you please illustrate the approach n.2 even if I dont have free disks?</div><div>I would like to start thinking about it and test it on a virtual environment.</div><div><br></div><div>Thank you in advance for your help and patience.</div><div>Regards,</div><div>Mauro</div></div><div><br></div><div><br></div><br><div><blockquote><div>Il giorno 28 set 2018, alle ore 14:36, Ashish Pandey <<a href="mailto:aspandey@redhat.com" rel="noreferrer" target="_blank">aspandey@redhat.com</a>> ha scritto:</div><br class="m_-4325851475516472332m_-6378917339899735691m_4766848556606636788Apple-interchange-newline"><div><div><div style="font-family:'times new roman','new york',times,serif;font-size:12pt"><br>We could have taken approach -2 even if you did not have free disks.
