by Peter Harris 20 May '14

I am trying to migrate my VMs from my old host running ovirt 3.3.4 to a new setup running 3.4.1. My basic set up is: OLD vmhost1 - ovirt 3.3.4 - NFS storages NEW ovirtmgr - ovirt 3.4.1 (virt only setup) - gluster storage domains vmhost2 - cluster1 vmhost3 - cluster2 vmhost4 - cluster2 vmhost5 - cluster3 vmhost6 - cluster3 My gluster volumes are created via gluster command line and I have All hosts are running scientific Linux 6.5, and the intention is to migrate vmhost1 to new environment cluster1. I have an NFS export storage domain which I am using to migrate VMs from vmhost1.

Migrate to Hosted Engine - problem with doc/web page
by Bob Doolittle 20 May '14

20 May '14

Hi, I'm trying to follow the instructions here: http://www.ovirt.org/Migrate_to_Hosted_Engine I've shut down my original engine and completed engine-backup. I've completed hosted-engine --deploy to the point where my new engine VM is up and running, and I've installed the 3.4-stable version of engine-install on it. Now I want to restore the backup on my new engine. However, at this point the instructions/how-to suddenly introduces a new host name "didi-lap" which was not mentioned previously: > engine-backup --mode=restore --file=backup1 --log=backup1-restore.log --change-db-credentials --db-host=didi-lap --db-user=engine --db-password --db-name=engine The only entities introduced in this How-To are: ovirttest.home.local The DNS CNAME record of the Engine (before and after migration) my-engine.home.local The underlying hostname of the original engine didi-box1.home.local The new machine which will run self-hosted engine I am not sure what (if anything) I should supply for db-host. In my original setup, my engine had the db locally (I presume - whatever the default was). In my new setup, my engine will have the same name as it did in the old setup (it was a VM previously, I took it down). Do I even need to specify the db-host or change-db-credentials arguments? Do these instructions require that the database was originally stored on an external entity (didi-lap) and that the database still resides there? Or does it backup/restore the database entirely? Thanks, Bob

"Could not connect host to Data Center" after rebooting, how to resolve?

19 May '14

Hi list, I had to do some fsck-related things last week on my ovirt box (centos, single node and NFS on localhost). Afterwards ovirt refused to start VMs according to the webinterface because it can't connect host to Data Center. On my OS it works fine (I just replaced the IP by 'IP'): [root@server ovirt-engine]# df Filesystem 1K-blocks Used Available Use% Mounted on /dev/mapper/vg_leiden-lv_root 51606140 6872592 42112108 15% / tmpfs 3978120 0 3978120 0% /dev/shm /dev/sdb1 495844 99542 370702 22% /boot /dev/mapper/vg_server-lv_home 62990260 2584272 57206196 5% /home /dev/sda1 5814366992 4629615452 1184751540 80% /raid IP:/raid/ovirt/data 5814367232 4629615616 1184751616 80% /rhev/data-center/mnt/IP:_raid_ovirt_data IP:/raid/ovirt/iso 5814367232 4629615616 1184751616 80% /rhev/data-center/mnt/IP:_raid_ovirt_iso in my event log in the webinterface I found correlation ID 7a735111 .

Well the NFS storage is mounted and looks fine. The directory is indeed looking fine: [root@leiden data]# ls -al total 12 drwxr-xr-x. 3 vdsm kvm 4096 Mar 30 03:27 . drwxr-xr-x. 4 vdsm kvm 4096 Mar 30 03:26 .. drwxr-xr-x. 5 vdsm kvm 4096 Mar 30 03:27 6bee0e2d-961c-453d-a266-e4623f91e162 -rwxr-xr-x. 1 vdsm kvm 0 Mar 30 03:27 __DIRECT_IO_TEST__ (and in the uuid there are indeed my VMs). How should I solve this? To me everything looks just fine. Cheers Boudewijn Ector
