Abstract
A computer-implemented method, according to one approach, includes: receiving a data operation request which includes an activated compound operation flag. The data operation request is added to a queue in a gateway node, and the data operation request is eventually transmitted to a disaster recovery site. An inode entry which corresponds to the portion of data is locked, and metadata associated with the inode entry is updated to indicate that the data operation request has been performed at the disaster recovery site. Supplemental data operation requests which correspond to the portion of data are also identified by evaluating the metadata associated with the inode entry. These supplemental data operation requests are transmitted to the disaster recovery site, and the metadata associated with the inode entry is updated to indicate that the supplemental data operation requests have been performed at the disaster recovery site. Furthermore, the inode entry is unlocked.
