Hi Carl, I think there is another thread here related to the migration to another network. As far as I know, the check liveliness try's to access the ovirt's health page. Does the new engine's ip has A/PTR record setup? Also, check the engine logs, once the HostedEngine VM is up and running.

major network changes

Hi We are in a process of changing our network connection. Our current network is using 10.8.256.x and we will change to 10.16.248.x. We have a HA ovirt cluster (around 10 nodes) currently configure on the 10.8.256.x. So my question is is it possible to relocate the ovirt cluster to the 10.16.248.x. We have tried to move everything to the new network without success. All the node seem to boot up properly, our gluster storage also work properly. When we try to start the hosted-engine it goes up but fail the liveliness check. We have notice in the /var/log/openvswitch/ovn-controller.log that he is triying to connect to the hold ip address of the hosted-engine vm. 019-07-16T18:41:29.483Z|01992|reconnect|INFO|ssl:10.8.236.244:6642: waiting 8 seconds before reconnect 2019-07-16T18:41:37.489Z|01993|reconnect|INFO|ssl:10.8.236.244:6642: connecting... 2019-07-16T18:41:45.497Z|01994|reconnect|INFO|ssl:10.8.236.244:6642: connection attempt timed out So my question is were is the 10.8.236.244 come from. The routing table for one of our host look like this estination Gateway Genmask Flags Metric Ref Use Iface default gateway 0.0.0.0 UG 0 0 0 ovirtmgmt 10.16.248.0 0.0.0.0 255.255.255.0 U 0 0 0 ovirtmgmt link-local 0.0.0.0 255.255.0.0 U 1002 0 0 eno1 link-local 0.0.0.0 255.255.0.0 U 1003 0 0 eno2 link-local 0.0.0.0 255.255.0.0 U 1025 0 0 ovirtmgmt Any help would be really appreciated.

Cinderlib managed block storage, ceph jewel

If you can give directions (some kind of history) , the dev might try to reproduce this type of issue. If it is reproduceable - a fix can be provided. Based on my experience, if something as used as Linux LVM gets broken, the case is way hard to reproduce.

That allowed me to perform the restore without bringing all VMs down, which was important to me, because if I had to shut down VMs, I was sure I wouldn't be able to restart them before the storage domain was back online. > > Of course this is a more a Linux problem than an oVirt problem, but oVirt did cause it ;-) > > Thanks, > Martijn. > > > > Op 19-7-2019 om 19:06 schreef Strahil Nikolov: >> >> Hi Martin, >> >> First check what went wrong with the VG -as it could be something simple. >> vgcfgbackup -f VGname will create a file which you can use to compare current metadata with a previous version. >> >> If you have Linux boxes - you can add disks from another storage and then pvmove the data inside the VM.
