This can break shared LVM storages because it fails to honor locking guarantees! LVM metadata corruption is possible with concurrent operations and Proxmox VE won't be aware of it actually being the same storage under the hood. > Alternatively, I think it could be possible to simply enable it on your > current storage (in storage.cfg directory), and do the move disk to > qcow2 format. > (but be carefull to not have existing internal snapshots, as it's not > supported to have both kind of snapshots at the same time) You can also just enable the flag for an existing LVM storage via the web UI/API/CLI, no need for manual editing. You will not be able to disable the flag anymore as long as qcow2 formatted images exist however. Moving disks to the same storage while changing formats is a possibility, yes. _______________________________________________ pve-user mailing list pve-user@lists.proxmox.com https://lists.proxmox.com/cgi-bin/mailman/listinfo/pve-user
