摘要
Techniques for recovering from a failure at a disaster recovery site are disclosed. An example method includes receiving an indication to shift control of a set of volumes of a plurality of volumes. The set of volumes is originally owned by a second storage node. The first storage node is a disaster recovery partner of the second storage node. The method includes shifting control of the set of volumes. The method further includes during the shifting, changing a status of a flag corresponding to a progress of the shifting. The method also includes during a reboot of the first storage node, determining the status of the flag and determining, based on the status of the flag, whether to mount the set of volumes during reboot at the first storage node.
