Hi all, I'm having problems during backup process because I can not get a zero-downtime backup process.
In my Proxmox server I have installed a new disk, SSD, with a VolumeGroup, and added to Proxmox storages.
I create a VM KVM using around 80% of the disk space available, VirtIO driver + RAW + direct LVM.
The backup server is a NFS storage.
The nodes and the NFS server are connected in a private network in the same rack
Checking with "lvs" all the process is Ok with many space available on the VG.
But on every backup I get around 1-5 minutes of downtime.
SSH connections to the KVM machine is unavailable...
Log shows that the live backup was Ok, but no...
