Abstract: In at least one embodiment, processing can include receiving a command at a first node in a system, wherein the first node manages first user data (UD) log resources and a second node of the system manages second UD log resources. The first and second nodes can generate sequence numbers from corresponding node-local sequences. Each command of a UD log is associated with a generic serial number (GENSN). Responsive to determining the command is a write I/O directed to logical addresses owned by the first node, the first node can perform processing to record the write I/O in the UD log without any internode communication with the second node. The recorded write I/O can be associated with a GENSN including a non-zero value that is a sequence number of the first node's local sequence and a zero value corresponding to the second node.
