This is really important for us .
we have a server with a persistent datablock with 200gb of space used as mysql datadir
3days ago our machine got into a problem and crashed so we shutdown the machine and start a new one with that persistent image but now the image is just 8GB and has a Installed os on that . opennebula database still tell us its persistent and has 200gb data by qemu img said:
qemu-img info /var/lib/one/gluster/145/1f73fdd57169fee71c652d0a717b6df4 image: /var/lib/one/gluster/145/1f73fdd57169fee71c652d0a717b6df4 file format: qcow2 virtual size: 8.0G (8589934592 bytes) disk size: 867M cluster_size: 65536 backing file: /var/lib/one/gluster/145/e639fa33f8ab49f7ed907c062d4899ef Format specific information: compat: 1.1 lazy refcounts: false
