I have run 3 node Ubuntu Gluster cluster (converted to Centos currently) acting as a backend for VMware and KVM hosts. </p> <p><br> </p> <p>Gluster's dis-advantage is the writes are equivalent of 30~40% of a single disk's speed but the read are as fast or faster (for multiple nodes) making it good enough for web and streaming. Advantages, it also with 3 nodes offers failover and a distributed raid 1 to protect against data loss. It is also very cheap to do needing no fancy and expensive hardware. </p> <p><br> </p> <p>Not sure why you need GFS if only one computer is uploading while other multiple (web) servers read? Even if you have multiple writes then Gluster strikes me as a potentially better solution for you as the write doesnt strike me as being significant.</p> <p><br> </p> <p><br> </p> <div id="Signature"> <div name="divtagdefaultwrapper" style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:; margin:0"> <div style="font-family:Tahoma; font-size:13px"> <div style="font-family:Tahoma; font-size:13px"> <div style="font-family:Tahoma; font-size:13px"> <p>regards</p> <p>Steven</p> <br> </div> </div> </div> </div> </div> <br> <br> <div style="color: rgb(49, 55, 57);"> <hr tabindex="-1" style="display:inline-block; width:98%"> <div id="divRplyFwdMsg" dir="ltr"><font style="font-size:11pt" color="#000000" face="Calibri, sans-serif"><b>From:</b> ubuntu-users-bounces@lists.ubuntu.com <ubuntu-users-bounces@lists.ubuntu.com> on behalf of Mark Haney <mark.haney@vifprogram.com><br> <b>Sent:</b> Tuesday, 2 February 2016 8:51 a.m.<br> <b>To:</b> Ubuntu user technical support, not for general discussions<br> <b>Subject:</b> iSCSI + GFS for web servers</font> <div> </div> </div> <div> <div dir="ltr">Anyone know of a decent howto/tutorial on how to setup GFS2 in Ubuntu for an iSCSI VM?
