Hello,
As I did not get help on users mailing list, I allow myself to post my
question here. Sorry if it's not the right place, but I can't find any
documentation.
I'm currently running an OCFS2 cluster on two hosts.
My ocfs2 partition is an iscsi disk mounted on both hosts debian1 and
debian2
I need to add a third host (debian3) 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.
root at debian1:~# cat /etc/ocfs2/cluster.conf
node:
ip_port = 7777
ip_address = 192.168.0.11
number = 0
name = debian1
cluster = ocfs2
node:
ip_port = 7777
ip_address = 192.168.0.12
number = 1
name = debian2
cluster = ocfs2
cluster:
node_count = 2
name = ocfs2
Same config on debian2.
I try to add the new node to the cluster, running this command on nodes
debian1 et debian2 :
root at debian1:~# o2cb_ctl -C -i -n debian3 -t node -a number=2 -a
ip_address=192.168.0.13 -a ip_port=7777 -a cluster=ocfs2
my new node is added to the config file, and node_count is incremented to 3.
then I do a "systemctl reload ocfs2" on debian1 and debian2.
I copy the cluster.conf file on debian3 and restart ocfs2 on it.
and in dmesg, I get :
[ 145.582469] o2net: Connected to node debian2 (num 1) at 192.168.0.12:7777

192.168.0.12:7777
Can anyone tell me how I can add a slot, so my new node can work ?
Thanks for your help.
Regards,
C?dric

Hi C?dric,
I guess it is because your shared disk is formatted with only 2 slots.
You can check it using debugfs.ocfs2.
If it is, you may update slot count using tunefs.ocfs2 -N <num_of_slot>.
Hope it will help you.
Thanks,
Joseph

Hi Joseph.
my shared disk is formatted with 2 slots :
root at debian2:~# debugfs.ocfs2 /dev/sdb -R stats | grep Slots
Max Node Slots: 2
I was hoping I can change it without unmounting my partition but it seems
not :
root at debian2:~# tunefs.ocfs2 -N 3 /dev/sdb
tunefs.ocfs2: Trylock failed while opening device "/dev/sdb"

Hi C?dric,
Now we don't support change the slot number when the device is online.
you should umount the OCFS2 filesystem if you want to update the slot number.
Thanks,
Alex

Not at all. Actually, other mail lists are under very low traffic now. I
think it's not bad to ask question on this devel list.
