DR plan
by 2707974＠gmail.com 28 Dec '23

28 Dec '23

Hi All, We wish to create some kind of DR plan for our OVM 4.4.10.7-1.0.22.el8 environment. Idea is to do storage replication of defined Storage Domains. steps: create LUN on storage present LUN to OVM create Storage Domain put VMs on Storage Domain on storage replicate LUN to another storage [or the same storage] Storage Domains contains OVF_STORE Now, recovery On live OVM present replica of LUN import Storage Domain But we cannot import replica LUN. Where to look for errors? Is this action possible it all? Facts OVM is the same version Storage is the same vendor LUN is browsable on SAN level and have differen WWIN, if we wish to add replicated LUN like new Storage Domain. Adding new Storage Domain mean that LUN will be formatted ... What I do wrong?

Re: How to restore VMs from shared storage domain when HE and VMs are not accessible?
by Jorge Visentini 27 Dec '23

I'm not sure, but... maybe: 1 - Import the Shared Domain Storage 2 - Export the data (VMs/Disks) to a mount point 3 - Create a Local Storage (the Cluster will changed) 4 - Import the data (VMs/Disks) to a Local Storage.

[ovirt4.4][rockylinux8.9][tg3] Communication down between engine and host after setting up network
by Cyril VINH-TUNG 27 Dec '23

27 Dec '23

Dear all I have an issue with ~same environment~ to make tg3 nic communicate between rocky linux 8.9 oVirt 4.4 engine and rocky linux 8.9 fresh installed host. Thanks to this post (https://forums.centos.org/viewtopic.php?t=65299) I had to make the ifcfg simplications to make engine communicate with the host and therefore be able to install the host via ovirt web UI. Then after setting up the network via ovirt and reboot the host, I lost the communicatiin between ovirt engine and the host (even ping does not work). Note that I have a virtualized pfsense between engine and host. All firewalls are opened. From anywhere else than the engine subnet I can communicate with the host and the engine can also communicate with any device on the same subnet than the host... so my thought is that there might be some incompatible parameter between pfsense and the host.... but then 'why did it work before the vdsm installation ? :-/ ). This last fact makes me think that it's a vdsm/nmstate/ethtool parameter that I have to tune... Any help would be much appreciated... (host is a hp proliant DL360 with tg3 3.137 module coming from base rocky linux) [code] filename: /lib/modules/4.18.0-513.9.1.el8_9.x86_64/kernel/drivers/net/ethernet/broadcom/tg3.ko.xz firmware: tigon/tg3_tso5.bin firmware: tigon/tg3_tso.bin firmware: tigon/tg3.bin version: 3.137 license: GPL description: Broadcom Tigon3 ethernet driver author: David S.

Hi, First of all, recreate the engine VM using your backup or starting from scratch. Then, just import the domain storages and your VMs will be there. Cheers!
