Abstract:
A method including creating a commit-in-progress context from a copy of a data object in a redirect-on-write file system; and begin storing the commit-in-progress context in a persistent storage device. The method further includes, while storing the commit-in-progress context in the persistent storage device: receiving a notification of a pending modification to the first data object, creating an update-in-progress context from a copy of the commit-in-progress context, and begin applying the modification to the update-in-progress context. The method further includes detecting that a connectivity error has occurred between the commit-in-progress context and the storage device, and in response, identifying whether the commit-in-progress context is successfully stored in the storage device. In response to identifying that the commit-in-progress context is not successfully stored: aborting the storing of the commit-in-progress context, assigning a new commit-in-progress context, and begin storing the new commit-in-progress context.
