[ovirt-users] [hosted-engine] Metadata too new error when adding 2nd host

Wed Apr 20 10:42:15 UTC 2016

Hi Didi & Martin,

I followed your instructions and are able to add the 2nd host. Thank you :)

This is what I've done:

[root at host01 ~]# hosted-engine --set-maintenance --mode=global

[root at host01 ~]# systemctl stop ovirt-ha-agent

[root at host01 ~]# systemctl stop ovirt-ha-broker

[root at host01 ~]# find /rhev -name hosted-engine.metadata

(Found 2 metadata files but the first one is red when I used 'ls -al' so 
I assume it is a leftover from the previous failed installation and 
didn't touch it)

BTW, how to properly clean the FC storage before using it with oVirt? I 
used "parted /dev/mapper/wwid mklabel msdos" to destroy the partition 
table. Isn't that enough?
