<div dir="ltr">There is no sbd on centos(redhat), in your case you can use cman+pacemaker and after that, create a volume group using the multipaths device and now you can create the filesystem using the new volume group and copy the oracle data, if you are using hp hadware you can use the ilo force fencing and if you are dell hadware you can use the idrac<br>

<div dir="ltr">Hi, everyone!<div><br></div><div>I have a running cluster on Centos 6.5, with drbd+cman+corosync+pacemaker 1.1.10 (as described in the latest guide). It is running Oracle DB on top of active/passive drbd resource.</div>
<div><br></div><div>Now, we got shared storage over multipath FC there, so we need to move from drbd to shared storage. And I got totally confused now - I can not find a guide on how to set things up. I see two options:</div>
<div>- use gfs2</div><div>- use ext4 with sbd</div><div><br></div><div>There are some guides on gfs2 in the net, however they all rely on RH set of cluster related stuff - luci, ricci, rgmanager and whatsoever... Is there any clue how and what to combine to get things going? How does pacemaker relate to all these RH tools?</div>
<div><br></div><div>Actually I do not need to access data on both nodes simoultaneously, Oracle runs on just one node. So, sbd looks like an option - we need to make sure that when we have no cluster connectivity (but have access to shared storage) only one node writes to the filesystem. But, again, there are just some old guides, and there is no sbd listed in 'pcs stonith list'...</div>
<div><br></div><div>Please point me to the right direction.</div><div><br></div><div>Thanks in advance,</div><div><br></div><div>Alex.</div></div>
