<body class='hmmessage'><div dir='ltr'>Hi Van,<br><br>I tried to upgrade to 8.3.15 and 8.3.16 but sync gets stalled in those versions as well. Only when I upgrade to 8.4.0, 8.4.1 and 8.4.2 sync is working fine. This testing I am doing in testing servers. I guess I have to follow same on production also. Are there any steps available for drbd version upgrade from 8.3 to 8.4? If we recreate metadata after version upgrade will it impact data on the disk?<br><br>Thanks<br> <br><div><hr id="stopSpelling">From: M.vandeLande@VDL-Fittings.com<br>To: catchvjay@hotmail.com; drbd-user@lists.linbit.com<br>Subject: RE: [DRBD-user] DRBD 8.3.13 Sync getting stalled with RHEL 6<br>Date: Tue, 22 Oct 2013 07:00:19 +0000<br><br>

<p class="ecxMsoNormal" style=""><span style="font-family:"Calibri","sans-serif";">Thanks Lars for replying. I don't have problem in upgrading DRBD to 8.4 but I am worried about data. Since two nodes are out of sync will upgrade on secondary
(removing 8.3 and installing 8.4) will force sync to finish? If it doesn't happen how should I approach primary upgrade?

<p class="ecxMsoNormal"><span style="font-family:"Calibri","sans-serif";">Hi Friends,<br>
<br>
I have already a DRBD 8.3.13 setup running on RHEL 6 servers. After recent kernel upgrade to 2.6.32-358.18.1.el6.x86_64, DRBD sync got stalled on the server. I have tried to invalidate secondary and start the sync but sync is alway 100% mark.<br>
<br>
[root@PdCuLx0503p ~]# cat /proc/drbd<br>
version: 8.3.13 (api:88/proto:86-96)<br>

<br>
<br>
I tried to install same version on non production RHEL6 servers but in that also Initial syncs are getting stalled. Is 8.3.13 supported on kernel 2.6.32-358.18.1 and later?</span></p>
