<div dir="ltr">Hi to all Gluster experts,<br><br>I have a cluster of 10 machines exposing a volume into which 12 other machines do many writes of large files (~100-300MB each).<br> In general I'm very happy with gluster. It's a great solution, and is quite stable (thanks for the great work!).<br>
<br>However, I have a problem which I was unable to solve yet, nor find any solution to in the documentation or on this list archive.<br><br>When the client machines write locally, and then just copy the files they created to the gluster mount - everything works great.<br>
When the client machines write directly to the gluster mounted volume I get a huge performance hit.<br>In one specific test case the difference was 20 minutes for the copy and 8 hours for the direct write.<br><br>I tried to set the iocache attributes of write-behind-window and flush-behind, but to no avail.<br>
<br>I will very much appreciate your help in solving this problem.<br><br>Thanks,<br>Ayelet<br></div>
