Abstract
A method is used in managing log transactions in storage systems. A first portion of a transaction log space is allocated from a persistent journal associated with a file system to a first core of a multi-core storage processor and a second portion of the transaction log space is allocated from the persistent journal to a second core of the multi-core storage processor. A set of per-core bitmaps is used for allocating a set of transaction log entries from the persistent journal. Each per-core bitmap is associated with a respective core of the multi-core storage processor. A per-core bitmap of the set of per-core bitmaps associated with a core of the multi-core storage processor is used for allocating a transaction log entry for a write request performed by the core.
