Opinion Needed: OCFS2 or GFS2 without any (Like Pacemaker) Cluster Components
We have one requirement for installing one of the software on two nodes by using shared file system (block). However, as we are running SLES 12.x VMs on Azure platform, we don't have option of using centralized shared storage system like iSCSI SAN or FC.
However, there were discussions going on to build OCFS2 along with DRBD (dual-primary) keeping expectations, if one nodes goes down, the other nodes will be available to access the software via web. They are fine to switch ips in the browser whenever they want to access software. But, without pacemaker can we run clustered file system.
