Hello,<br>i have a 2 node cluster system requirement with <br>1. A master/slave DRBD resource (ms_drbd)<br>2. A primitive Filesystem resource (drbd_fs)<br>3. A master slave resource, X<br>4. A clone resource Y<br><br>The logs from software application i.e. from resource X and Y need to be saved on DRBD partition. Thus, these applications shall be started after filesystem has been mounted.<br>
<br>So , I need to define following order clauses:<br><br>crm configure order fs--after-drbd inf: ms_ddrbd: promote drbd_fs:start<br>crm configure order X--after-drbd_fs inf: drbd_fs X<br>crm configure order Y--after-drbd_fs inf: drbd_fs Y<br>
<br><br>But with above order clauses, X and Y will get started only on the Active node (as filesystem will be mounted on that node).<br><br>So, how shall I start resource X and Y on the standby node as well?<br><br>Please suggest how shall I achieve the system requirement.<br>
<br>Also one more query: what exactly is the different between the following two order clauses:<br><br>crm configure order X--after-drbd_fs inf: drbd_fs X<br><br>and <br><br>crm configure order X--after-drbd_fs inf: drbd_fs X:start<br>
<br>Thanks and regards<br>Neha Chatrath<br>
