[Ocfs2-users] heartbeat and slot issues.

[Ulf Zimmermann]

After the clone, you want to probably run tunefs.ocfs2 -U to reset the UUID. This is one of the steps we do when cloning volumes for database refreshes.

Subject: [Ocfs2-users] heartbeat and slot issues.

I setup a host with an ocfs partition on a san and then cloned that host to another and renamed. Both machines mount their ocfs partitions but give the following errors.


Host that was cloned:
(1888,0):o2hb_do_disk_heartbeat:762 ERROR: Device "sdb1": another node is heartbeating in our slot!

Clone:

This didn't seem to be a problem, but im noticing the host are no longer seeing the same data. I unmount the drives and remounted and they were the same again.


Thanks for any guidance,


cat /etc/ocfs2/cluster.conf
node:
        ip_port = 7777
        ip_address = 10.x.x.248
        number = 0
        name = smes01
        cluster = ocfs2

node:
        ip_port = 7777
        ip_address = 10.x.x.249
        number = 1
        name = smes02
        cluster = ocfs2

cluster:
        node_count = 2
        name = ocfs2

cluster.conf same on both hosts.
