I have a Synology NAS. When configuring VDSM as the remote replication destination for Snapshot Replication, it prompts that the command execution failed and asks to log in to DSM again and try. Snapshot Replication indicates that the remote destination needs to be Btrfs. In VDSM, my storage space is shown as Btrfs, but the actual physical machine mount point is Ext4. Is this the reason for the issue?
