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

[Carlos Xavier]

Hi all.

We have a OCFS2 clustered file system running with Pacemaker stack over a
Dell storage.
Now we need to enlarge the size of the file system. We already have grown it
at the storage and with fdisk it was recreated the partition to allocate the
new available size.

To resize the disk I umounted the filesystem and left the DLM running.

When I tried to resize the OCFS2 filesystem with tunefs.ocfs2, it couldn't
find the cluster stack.

apolo:~ # tunefs.ocfs2 -S /dev/mapper/storage1-part2
tunefs.ocfs2: Unable to access cluster service while closing device
"/dev/mapper/storage1-part2"

We are running a OpenSUSE 13.2 with the packages:
pacemaker-1.1.12.git20140904.266d5c2-1.5.x86_64
ocfs2-tools-o2cb-1.8.2+git.1361836695.ff84eb5-11.1.4.x86_64
ocfs2-tools-1.8.2+git.1361836695.ff84eb5-11.1.4.x86_64


This is the state of the filesystem when mounted:
