Consolidation Failed

[opk.giandomenico]

Hello, 

i have a consolidation error on a proxmox environment, i have 2 overlay files to consolidate on the same vm, i think that i have to consolidate the most recent one. What i have to do with the the older overlay file? could i remove it is there a best practice to follow and avoid data corruption?

 

Best regards

Hi @opk.giandomenico,

Could you give us a bit more context on where NAKIVO is involved here?

We want to make sure we can actually help! If it's a Proxmox issue, it is better to contact the Proxmox support team.
