Hello
Retried from scratch; and still have an error when trying to bring up
the second cluster :
root@LAB-virtm6:/# o2cb register-cluster ocfs2new
o2cb: Internal logic failure while registering cluster 'ocfs2new'
root@LAB-virtm6:/mnt/vol1_iscsi_san1# o2cb list-clusters
ocfs2
ocfs2new
Can anybody help me please ?
I don't know if o2cb stack can have multiple clusters on the same node.
With pacemaker
stack, once we setup a pacemaker cluster stack, we can have multiple
ocfs2 instance, i.e
mkfs and mount multiple ocfs2 FS on the same node.
Why do you want to setup multiple o2cb cluster on the same node? I
never know this need
of usage so far :)
Maybe, others can help on your question.
Thanks,
Eric

Hello,
I guess I did something wrong the first time.
I retried three times, and it worked three times. So I guess ocfs
1.6 and 1.8 are compatibles :)
Not it's time to set up a second ocfs2 cluster on my debian 9
server (ocfs 1.8), and I get this error when trying to mkfs.ocfs2 :
root@LAB-virtm6:~# mkfs.ocfs2 /dev/mapper/data_san_2
mkfs.ocfs2 1.8.4
On disk cluster (o2cb,ocfs2new,0) does not match the active
cluster (o2cb,ocfs2,0).
mkfs.ocfs2 will not be able to determine if this operation can be
done safely.
To skip this check, use --force or -F
The running cluster on this host is :
root@LAB-virtm6:~# o2cluster -r
o2cb,ocfs2,local
I'm trying to add an "ocfs2new" cluster :
root@LAB-virtm6:~# o2cb add-cluster ocfs2new
root@LAB-virtm6:~# o2cb add-node --ip 192.168.0.12 --port 7777
--number 1 ovfs2new LAB-virtm6
root@LAB-virtm6:~# o2cb add-node --ip 192.168.0.13 --port 7777
--number 2 ovfs2new LAB-virtm7
root@LAB-virtm6:~# o2cb list-clusters
ocfs2
ocfs2new
root@LAB-virtm6:~# o2cb cluster-status
Cluster 'ocfs2' is online
Even if I restart services or reboot, cluster 'ocfs2new' never
goes online.
What am I doing wrong ?
