摘要:
A machine implemented process and system is provided. The process determines if any right granted to an entity for performing an I/O operation associated with a data container stored at a first storage volume is to be revoked. The right itself may be cached at the first storage volume and resident at a second storage volume. A recall message is sent to the node that manages the second storage volume. Any pending I/O operation is completed, after the message is sent and before the right is revoked. Thereafter, the right is revoked and the cached copies of the right are invalidated.
摘要:
A technique that provides the ability to copy or move a volume that includes one or more quota structures, by using logical replication, where the volume and any quota structures in it are immediately accessible upon completion of the copy/move operation, and where the quota structures' usage control functionality is immediately functional and reliable upon completion of the copy/move operation. A user does not have to reinitialize the quota mechanism or invoke a quota scanner at the destination.
