<div dir="ltr"><div><div><div><div><div><div>Hi all,<br><br></div>We're playing around with new versions and uprading options. We currently have a 2x2x2 stripped-distributed-replicated volume based on 3.3.0 and we're planning to upgrade to 3.4 version.<br>
<br></div>We've tried upgrading fist the clients and we've tried with 3.4.0, 3.4.1 and 3.4.2qa2 but all of them caused the same error:<br><br>Failed to get stripe-size<br><br></div>So it seems as if 3.4 clients are not compatible to 3.3 volumes. Is this assumtion right?<br>
<br></div>Is there any procedure to upgrade the gluster from 3.3 to 3.4 without stopping the service?<br></div>Where are the compatibility limitations between these 2 versions?<br><br></div>Any hint or link to documentation would be highly appreciated.<br>
<br>Thank you in advance,<br>Samuel.<br></div>
