Hi all,

I´m a complete noob to Linux and Proxmox. I clustered 2 nodes and after that, I ran into this issue while trying to clone a CT:

Code: 
create full clone of mountpoint rootfs (Machines:225/vm-225-disk-0.raw)
Formatting '/var/lib/vz/images/2500/vm-2500-disk-0.raw', fmt=raw size=8589934592 preallocation=off
Creating filesystem with 2097152 4k blocks and 524288 inodes
Filesystem UUID: d1af6245-4b02-4abb-9228-468d5dedf9e9
Superblock backups stored on blocks:
    32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632
mount: /var/lib/lxc/2500/.copy-volume-2: cannot mount /dev/loop2 read-only.
Specified filename /var/lib/lxc/2500/.copy-volume-1 does not exist.
TASK ERROR: clone failed: command 'mount -o ro /dev/loop2 /var/lib/lxc/2500/.copy-volume-2//' failed: exit code 32

I would be happy to get your advise, how I can solve that.

Cheers
 
Hi,
please share the output of pveversion -v and pct config 225? What kind of storage is Machines. Are you cloning on the same node?
 
Hi,
I have the same error but for moving a storage file to an other HDD.
