摘要
According to examples, a system may include an upstream volume controller having: a processor and a non-transitory machine-readable storage medium. The storage medium may include instructions executable by the processor to freeze an upstream volume, the upstream volume being in a replication set with a downstream volume, receive a snapshot creation request, create a snapshot of the upstream volume, and send one of a snapshot permit message or a snapshot abort message to a downstream volume processor. The instructions may also be executable by the processor to unfreeze the upstream volume responsive to at least one of the sending of the one of the snapshot permit message or the snapshot abort message or expiration of a timeout corresponding to a maximum time period during which the upstream volume is to remain frozen.
