Embodiment Construction

[0012] see figure 2 , which is a flow chart of steps of a method for reorganizing a disk array according to an embodiment of the present invention. In the figure, in step S1, when the disk array executes a job schedule, a hard disk is inserted to perform hard disk replacement operation, and the hard disk includes an expansion capacity. Then, in step S2, check the usage status of each hard disk in the disk array and calculate a total available capacity of the disk array. When a new hard disk is inserted into the disk array, the capacity detection will be executed automatically or the user will be asked to decide whether to execute it. Next, in step S3, it is judged whether to execute the disk array expansion program. If not, as shown in step S5, the disk array reorganization method of the present invention can continue to execute the original work schedule.

[0013] If the disk array expansion program is to be executed, step S4 is executed to determine whether to use the la...

Abstract

The invention discloses a method for reconstructing a disk array, which is applicable to a disk array and comprises the following steps: firstly, replacing a hard disk in the disk array, wherein the hard disk comprises an expanded capacity; then checking using condition of each hard disk in the disk array and calculating a total available capacity of the disk array; afterwards, performing a disk array expanding program for adding the expanded capacity into the total available capacity; and finally, using the total available capacity and performing the work schedule continuously.

Description

【Technical field】 [0001] The invention relates to a disk array, in particular to a method for reorganizing the disk array. 【Background technique】 [0002] Disk array (Redundant Array of Inexpensive Disks, RAID) is a hard disk structure commonly used in large servers. This hard disk structure can combine several hard disks into a single hard disk for use. This feature has appeared in the Linux kernel version 2.2. Ordinary disk arrays must have a special hardware control card to operate, but the Linux kernel has the ability to simulate disk arrays by software, which means that the machine itself does not need to purchase additional special hardware devices, and can directly emulate several hard disks. As a disk array, its stability and performance are quite excellent. In addition, most general hardware disk arrays can only add the entire hard disk to the array, but software emulation can only use a certain partition on the hard disk without affecting other partitions. Ther...
