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

Hello Gang,
Tank you for your fast answer.

OK?

The file system is mounted at boot when the Pacemaker starts, as it is
configured on it.

>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.  

This is how it is mounted
apolo:~ # mount | grep ocfs2 
/dev/mapper/storage1-part2 on /export type ocfs2
(rw,noatime,heartbeat=none,nointr,data=ordered,errors=remount-ro,atime_quant
um=60,localalloc=1,cluster_stack=pcmk,coherency=full,user_xattr,acl)

>Then do the file system extension command.

With the filesystem mounted the same issue happens.
apolo:~ # tunefs.ocfs2 -S /dev/mapper/storage1-part2
tunefs.ocfs2: Unable to access cluster service while closing device
"/dev/mapper/storage1-part2"

>If still not work, please report a bug.

As openSUSE 13.2 isn't supported anymore, I don't know if they will take a
look at this.

Is there a way I can change the stack of the filesystem, extend it and
change the stack back to Pacemaker?

Carlos.
