There were two nodes with the vdi metadirectory and third node with just vm blocks and no metadata. Next i stopped collie on one of the two nodes - which had the vdi metadirectory. After this the vm blocks were recovered/redistributed evenly between the remaining two nodes. However the vdi metadirectory was not created/recovered on the third node :( Thanks Alex |
