Box 1254, Clausthal-Zellerfeld, D-38670, Germany Abstract: The overhead brings by metadata journaling is extra space and performance degrade caused by frequent journal data flush. A journal file system based remote journal scheme was designed and implementation. The remote journal scheme removes the frequent journal I/O activities from local disk to remote server. According to the experiments in this paper, remote journal increases about 8% to 19% performance, but the penalty is light. Although remote journal does need more CPU time for network transfer, the overhead is less than 8%. And the extra network bandwidth taken by remote journal is less than 6% in metadata bound workload. © (2013) Trans Tech Publications, Switzerland.
