Problems solved by technology

However, the log file system does not perform well in frequent system power outages or crash scenarios.
The main reason is that the log and data of the file system are placed on the same disk. When a disk fails, it is difficult to recover
In addition, log file systems generally use exception buffering to prolong the time that log transactions stay in memory, thereby increasing the risk of log loss

Abstract

The invention discloses a method and device for managing transaction information in a cluster file system. The method includes: in the cluster file system, after executing a write operation transaction in the cluster file system, acquiring the real-time processing state of the transaction; according to the real-time processing state of the transaction, updating the log data corresponding to the transaction.

Description

technical field [0001] The invention relates to the field of information processing, in particular to a method for managing transaction information in a cluster file system. Background technique [0002] The log file system is based on the traditional file system, adding log records of file system changes. In the log file system, all file system changes will be recorded in the log, and the file system will write updated metadata and file content to the disk every once in a while. Before modifying the metadata, a record will be written to the log first, which describes what to do and which metadata to modify. The OCFS (Oracle Cluster Filesystem, cluster file system) file system does not process the log itself. It is completed by calling the Journaling block device (JBD). The interaction of OCFS writing JBD uses three basic units: log records, atomic operations and affairs. [0003] The OCFS file system is a journal-supporting file system that is widely used in the fields o...
