[Ocfs2-users] Adding new node to an online OCFS2 cluster
Hello,
I'm currently running an OCFS2 cluster on two hosts.
My ocfs2 partition is an iscsi disk mounted on both hosts.
I need to add a third host to this cluster.
I've set up iscsi (& multipath), but now I'm looking for the
correct way
to add the ocfs2 partition to my existing cluster.
Actual hosts : hostA and hostB (same config) :
root at hostA:~# cat /etc/ocfs2/cluster.conf
node:
ip_port = 7777
ip_address = 192.168.155.16
number = 1
name = virtm5
cluster = ocfs2
node:
ip_port = 7777
ip_address = 192.168.155.17
number = 2
name = virtm6
cluster = ocfs2
cluster:
node_count = 2
name = ocfs2
hostC has no cluster.conf file.
How do I "Live-add" hostC to this existing cluster ? I did not find a
doc
explaining this. Maybe I did not look in the right place...
Found that :

I would prefer an official doc.

[Ocfs2-users] Adding new node to an online OCFS2 cluster
I've set-up a lab with a 2-node OCFS2 cluster and a new third one. I ran, on the two nodes : o2cb_ctl -C -i -n hostC -t node -a number=2 -a ip_address=192.168.0.18 -a ip_port=7777 -a cluster=ocfs2 systemctl reload ocfs2 then I copied the config file on hostC and restart ocfs2 on hostC. I get the error : [ 7594.853214] (mount.ocfs2,11753,0):ocfs2_find_slot:490 ERROR: no free slots available! [ 7594.853467] (mount.ocfs2,11753,0):ocfs2_mount_volume:1859 ERROR: status = -22 Any idea ? 2017-11-07 8:37 GMT+01:00 BASSAGET C?dric <cedric.bassaget.ml at gmail.com>:> Hello, > I'm currently running an OCFS2 cluster on two hosts. > My ocfs2 partition is an iscsi disk mounted on both hosts. > > I need to add a third host to this cluster. > I've set up iscsi (& multipath), but now I'm looking for the correct way > to add the ocfs2 partition to my existing cluster. > > Actual hosts : hostA and hostB (same config) : > root at hostA:~# cat /etc/ocfs2/cluster.conf > node: > ip_port = 7777 > ip_address = 192.168.155.16 > number = 1 > name = virtm5 > cluster = ocfs2 > node: > ip_port = 7777 > ip_address = 192.168.155.17 > number = 2 > name = virtm6 > cluster = ocfs2 > cluster: > node_count = 2 > name = ocfs2 > > hostC has no cluster.conf file. > > How do I "Live-add" hostC to this existing cluster ?
