Abstract
The invention discloses a magnetic disc fusion method which comprises the steps: (1), deploying a hardware environment; (2), arranging a hardware RAID (Redundant Array of Independent Disk) group and carrying out physical partitioning; (3), realizing re-fusion of the physical partitions in the hardware RAID group to form logic partitions; (4), converting the logic partitions into logical volumes; and (5), mounting the logical volume. The magnetic disc fusion method can enable read/write performances of all underlying magnetic discs to be played, so as to improve the work efficiency of a system. By re-fusion based on the physical partitions of the existing hard RAID group, the cost is saved.
Description
Technical field
The present invention relates to computer realm, be specifically related to a kind of disk fusion method.
Background technology
Disk array is direct-connected or link to each other with main frame by network outside main frame as autonomous system.Disk array has a plurality of ports to be connected by different main frames or different port.The different port of a main frame connection array can promote transmission speed.In the disk array, the hard RAID(Redundant Array of Independent Disk that sets) and divide to shine upon behind the Physical Extents and use to main frame, and do not do the setting of any operating system aspect in host side, its way can only be brought into play the performance of part disk in the disk array, and efficient is lower.And if need to increase the space to Physical Extents, can only format first, and the deletion subregion, then repartition the space.
Present disk array, the weak point of its existence comprises:
Mapping is used to main frame, and the maximum function of disk array can only be confined to the disk read-write performance in the single hardware RAID group, and can not bring into play the readwrite performance of all disks in the whole disk array;
Use RAID can realize fault-tolerant or accelerate the function of reading and writing data speed, but can't be under the prerequisite of not losing partition data the management zone capacity.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of disk fusion method, can effectively bring into play the readwrite performance of all disks in the whole disk array.
A kind of disk fusion method that the present invention proposes, its improvements are that described method comprises the steps:
(1) disposes hardware environment;
(2) disk array arranges the hardware RAID group, and carries out Physical Extents;
(3) Physical Extents in the described hardware RAID group is realized again merging, form logical partition;
(4) described logical partition is converted to logical volume;
(5) carry logical volume.
Wherein, step (1) deployment hardware environment comprises:
Server that (SuSE) Linux OS is installed of front end, rear end directly connect or by SAN(StorageAccess Network) Disk Array that comprises at least two disks of network connection.
Wherein, described Disk Array comprises and can realize various other Magnetic Disk Controllers of RAID level.
Wherein, step (2) realizes again fusion to the Physical Extents in the described hardware RAID group, only needs arbitrarily to adopt a kind of rank to carry out the ground floor fusion and gets final product.
Wherein, described hardware RAID group comprises the hardware RAID of at least one.
Wherein, step (3) realizes that to the Physical Extents in the described hardware RAID group fusion is to finish at operating system layer again.
Wherein, step (4) converts described logical partition to logical volume by lvcreate order realization.
Wherein, be implemented on the software RAID aspect not under the prerequisite of obliterated data according to the management function of logical volume in the operating system layer, the subregion capacity is increased or reduces.
Compared with the prior art, beneficial effect of the present invention is:
Existing technology can only be brought into play the readwrite performance of part bottom disk, can bring into play the readwrite performance of whole bottom disks by the present invention, thereby improves the work efficiency of system.
The Physical Extents of the present invention in existing hardware RAID merges again, provides cost savings.
Description of drawings
Fig. 1 is the process flow diagram of disk fusion method provided by the invention.
Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail.
A kind of disk fusion method that the present invention proposes, its process flow diagram as shown in Figure 1, the method comprises the steps:
(1) disposes hardware environment;
Wherein disposing hardware environment comprises:
Server that (SuSE) Linux OS is installed of front end, rear end directly connect or by Disk Array that comprises two disks of SAN network connection at least.Described Disk Array comprises can realize various other Magnetic Disk Controllers of RAID level.
(2) disk array arranges the hardware RAID group, and carries out Physical Extents; Wherein the hardware RAID group comprises the hardware RAID of at least one.
(3) Physical Extents in the described hardware RAID group is realized again merging, form logical partition; Physical Extents in the described hardware RAID group is realized again merging finishing at operating system layer, be implemented on the software RAID aspect not under the prerequisite of obliterated data according to the management function of logical volume in the operating system layer, the subregion capacity is increased or reduces.
(4) described logical partition is converted to logical volume;
Wherein, described logical partition being converted to logical volume is to realize by the lvcreate order.The lvcreate order that carries by (SuSE) Linux OS can realize conversion and format, its objective is the disk space after merging is converted to the form that operating system can be identified.
(5) carry logical volume.
Should be noted that at last: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit, although with reference to above-described embodiment the present invention is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or be equal to replacement the specific embodiment of the present invention, and do not break away from any modification of spirit and scope of the invention or be equal to replacement, it all should be encompassed in the middle of the claim scope of the present invention.
