[Ocfs2-users] How do I resize Ocfs2 filesystem using Pacemaker stack?

Could you use "crm_mon" comand to identify the current cluster status is OK?
Next, could you mount this partition first? just want to know if this partition is integrated, since most people use LVM to extend the disk.  
Then do the file system extension command.
If still not work, please report a bug.

Thanks
Gang
