Proxmox 9.1.6 taking a snapshot takes up t 15 minutes

[HenkS]

Taking a snapshot from a vm with 3 qcow2 disks in total of 7Tb takes approxmately 12 minutes, the vm isn't reachable while snapshotting is running.
Is this normal behavior ? ( in VMware less then a second, while users are not affected with outage)
The disk are on a full SSD NFS share.

Hi @HenkS , welcome to the forum.

This is an expected behaviour for QCOW snapshots over NFS. VMware does not use QCOW, their proprietary VMDK format employs completely different structure and snapshot architecture.
