Because of this Volume availability will not be affected if any issues with Glusterd or Glusterd is upgraded. All the mounts will reconnect once the Glusterd comes back up. CLI operations from that node may not be available but IO will not be affected if the Glusterd is down (New mounts can't be created, but existing mounts should work without Glusterd).<br></div><div><br></div><div>stop-all-gluster-processes.sh is available as part of installation, it can be used to stop all the processes (Check in /usr/share/glusterfs/scripts)</div><div><br></div><div>--<br></div><div>Thanks and Regards</div><div id="Zm-_Id_-Sgn" data-sigid="3848334000000010003" data-zbluepencil-ignore="true"><div>Aravinda<br></div><div>Kadalu Technologies</div></div><div><br></div><div class="zmail_extra_hr" style="border-top: 1px solid rgb(204, 204, 204); height: 0px; margin-top: 10px; margin-bottom: 10px; line-height: 0px;"><br></div><div class="zmail_extra" data-zbluepencil-ignore="true"><div><br></div><div id="Zm-_Id_-Sgn1">---- On Mon, 05 Feb 2024 22:40:30 +0530 <b>Anant Saraswat <anant.saraswat@techblue.co.uk></b> wrote ---<br></div><div><br></div><blockquote id="blockquote_zmail" style="margin: 0px;"><div dir="ltr" class="zm_414335516218564369_parse_848289701506616423"><p class="x_1122416758elementToProof" style="margin-top: 0px; margin-bottom: 0px;"><span class="colour" style="color:rgb(0, 0, 0)"><span class="font" style="font-family:Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif"><span class="size" style="font-size:12pt">Hello Everyone,</span></span></span><br></p><p class="x_1122416758elementToProof" style="margin-top: 0px; margin-bottom: 0px;"><span class="colour" style="color:rgb(0, 0, 0)"><span class="font" style="font-family:Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif"><span class="size" style="font-size:12pt"><br></span></span></span></p><p class="x_1122416758elementToProof" style="margin-top: 0px; margin-bottom: 0px;"><span class="colour" style="color:rgb(0, 0, 0)"><span class="font" style="font-family:Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif"><span class="size" style="font-size:12pt">I am using GlusterFS 9.4, and whenever we
