Abstract
Techniques for processing I/O operations include: receiving a write I/O operation that writes first data to a target location, wherein the target location is represented as a logical device and offset within a logical address space of the logical device; storing a log record for the write I/O operation in a log file; and performing first processing of the log record. The log record includes log data, comprising the first data, and a log descriptor. The log descriptor includes a target logical address for the target location in a file system logical address space. The log descriptor includes a first value denoting the binary logarithm of an extent size of the first logical device. The first processing includes flushing the log record from the log file to store the first data of the log record on an extent of physical storage provisioned for the logical device.
