Abstract
A computer-implemented method according to one embodiment includes, in response to a determination that a predetermined operation has been performed on an object of a first file stored on a first cluster site, storing predetermined information about the object of the first file stored on the first cluster site. The predetermined information is stored on an extended attribute of the first file stored on the first cluster site. In response to a determination that the predetermined operation is performed on an object of a first file stored on a second cluster site, the predetermined information is removed from the extended attribute of the first file stored on the first cluster site. In response to a determination that a failure event has occurred on a queue of the first cluster site, a predetermined recovery process is performed, thereby enabling fulfillment of entries of the queue of the first cluster site.
