Decoding "correct address" - glusterHostsList should return any
ipAddress that engine knows as being associated with host.
It could be either ipAddress used while adding host (stored as hostname
in vds_static) or any of the ipAddresses populated in vds_interface
table (addr column) .
I do not have enough knowledge about this bit of code to say what
entries are made in vds_interface table. I know there's an entry for
ovirtmgmt here but not sure if this gets added as part of addHost flow
or not.
thx

Hi all,
I'm testing the bootstrapping of host without reboot on Fedora 18. After
host's bootstrap,
Ifconfig output returns this:
ovirtmgmt: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 10.70.37.219 netmask 255.255.254.0 broadcast 10.70.37.255
<snipped>
virbr0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
inet 192.168.122.1 netmask 255.255.255.0 broadcast
192.168.122.255
<snipped>
Running*glusterHostsList* vdsm verb, returns the ip address
192.168.122.1, whereas my host has been added with ip address 10.70.37.219
If I reboot the host, the virbr0 bridge is removed, and there's no issue.
The vdsm verb glusterHostsList - returns ipAddress of host +
output of gluster peer probe. This is needed because a periodic
sync job needs to make sure that the hosts added in engine are in
sync with the gluster cli (hosts could also be added/removed from
gluster cli).
How can we make sure glusterHostsList picks the correct ipAddress?
Can you define (in plain English) what is the "correct" address?
The host may have multiple valid addresses (storage, migration, display,
whatnot).
Only when it's clear to us, we can start expressing this in Python.
Reading the inetinfo based on bridge has been vetoed as we are
doing away with bridges.
It would also work if virbr0 was updated in vds_interfaces table.
Since this is not happening either - we have an issue.
It might be a valid hack to drop this default virbr0 on vdsm start - not
only the libvirt definition thereof, but also the running kernel device.
However, as expressed above, this would not solve your problem when you
have a currently-running host with multiple addresses.
Dan.
