Design and Implementation on RAID On-line Expansion Based on Linux
Jing Liu · Jisuanji gongcheng · 2007
This paper designs and implements on-line expansion function in RAID system base on Linux,which allows RAID system to keep receiving requests from user while expanding.This function promotes the usability of the system.It also describes the implementation of on-line characteristic while using the simple method for RAID structure expansion and the solution to deal with the conflict between data migration and user’s requests.Experiments show that on-line expansion is stable in a long time running and the performance is acceptable.
