Since my last post I’ve been fighting to get the cluster back to some semblance of stability. Doesn’t look like that’s going to happen. However, there isn’t anything out there that approaches the ease of configuration, fault tolerance and hyperconverged storage I’m looking for. So…I’m making sure I have a backup copy of my VMs (especially Grafana) that would be problematic to rebuild, and then I’ll blow away the entire cluster and start over from scratch.
First challenge is backups. I found this link which describes what appears to be the simplest process: Backup and restore VMs in Nutanix CE
I’ve had to modify this a bit for my particular circumstances, but it appears to be working well. First, I’m lucky enough to have a Unraid NAS that holds all my media. Plenty of space and it happens to support NFS. With some trial and error and the instructions above I managed to work out the following command:
qemu-img convert -c nfs://127.0.0.1/default-container-46437110940265/.acropolis/vmdisk/be09f08c-56bf-472c-b8a6-16c022333ca5 -O qcow2 nfs://192.168.169.8/mnt/user/vmware/UnifiVideo.qcow2
Using this command and the previous instructions I was able to send the backup qcow2 image directly to Unraid for backup purposes. It sure would be nice to have a checkbox option, but this will do for now. Also, be sure to use the screen option in the other post because it’s likely your session will time out on modestly sized VMs.
