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 Cédric <cedric.bassaget...@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@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 ?
