Detailed description of the invention
For problems of the prior art, a kind of data processing method is proposed in the embodiment of the present invention, shouldMethod can be applied in the KVM virtual machine simulating on physical server. In the operation of KVM virtual machineIn process, the method is for data are processed, and this processing is specifically as follows to write processes or read placeReason.
In the embodiment of the present invention, KVM virtual machine uses the disk mirroring file storage data of QCOW2 form,This disk mirroring file comprises metadata information file and multiple data file, this metadata information file and everyIndividual data file is all unique files, i.e. separate metadata message file and each data file. As Fig. 2Shown in, be the structural representation that comprises the disk mirroring file of metadata information file and multiple data files,In Fig. 2, taking 4 data files as example, in practical application, the quantity of data file can be selected arbitrarily.
Wherein, the content that metadata information file comprises specifically can include but not limited to: metadata and dataWrite quantity. This metadata comprises the positional information of each data file etc., by the position of this data fileInformation can find this data file. It is to be greater than 1 positive integer that these data write quantity, in actual applications,Can directly represent that by numeral data write quantity, as 2,3 etc., also can use RAID (RedundantArraysofIndependentDisks, raid-array) information represents that data write quantity, asRepresent that with RAID1 2 data write quantity. In addition, in metadata, can also comprise position relationship table,This position relationship table for the mark of record data, store these data data file positional information andCorresponding relation between the stored position information of the data block of storing these data in corresponding data file. BaseIn this stored position information, can from corresponding data file, read this data.
Wherein, the content that data file comprises specifically can include but not limited to real data.
Wherein, multiple data files are stored in the same storage on the affiliated physical server of KVM virtual machineIn block device, or multiple data file is stored in respectively on the physical server under KVM virtual machine notIn same memory block equipment, memory block equipment can be the block device disk of a fixed size. For example, numberAccording to file 1 be stored in memory block equipment 1, data file 2 is stored in memory block equipment 2, data literary compositionPart 3 is stored in memory block equipment 3, data file 4 is stored in memory block equipment 4.
Wherein, in data file, when data writing, the data that write are stored with data block form,The space that is data file is divided into many data blocks, and data are just stored in these data blocks.
Under above-mentioned application scenarios, as shown in Figure 3, the processing method of these data is on can be virtual by KVMQEMU carries out, and can comprise the following steps:
Step 301, obtains the first data to be written, and according to the metadata in metadata information file, reallyGiven data writes the positional information of number of data file.
Step 302, according to each positional information of determining, is written to corresponding data file by the first dataIn freed data blocks in.
In the embodiment of the present invention, the first data are written in the freed data blocks in corresponding data fileAfterwards, inform the domestic os of KVM virtual machine, and by the mark of the first data, storage the first numberAccording to the positional information of data file and the data block of storage the first data in the corresponding data fileCorresponding relation between stored position information is recorded in metadata, as this corresponding relation is recorded to metadataPosition relationship table in.
For example, in the time that data write quantity and are 2, the metadata in metadata information file comprises data file 1The positional information of positional information, data file 3 of positional information, data file 2 and data file 4When positional information, determine the positional information of 2 data files, as the positional information of specified data file 1Positional information with data file 2. Further, utilize the positional information of data file 1, from data literary compositionIn part 1, obtain freed data blocks A, and the first data are written in the freed data blocks A of data file 1;Afterwards, in the position relationship table of metadata, record mark, the data file 1 of the first data positional information,Corresponding relation between the stored position information of freed data blocks A in data file 1. And, utilize numberAccording to the positional information of file 2, from data file 2, obtain freed data blocks B, and the first data are written toIn the freed data blocks B of data file 2; Afterwards, in the position relationship table of metadata, record the first dataPositional information, the memory location letter of freed data blocks B in data file 2 of mark, data file 2Corresponding relation between breath.
The said process of the embodiment of the present invention is data writing process, can comprise in addition data read process,In data read process, obtain the mark of the second data to be read; According to the mark inquiry of the second dataThe corresponding relation recording in metadata, obtains the positional information of the data file of storing the second data; According to depositingStore up the positional information of the data file of the second data, from corresponding data file, determine a spendable numberAccording to file; According to the mark of the positional information of the data file of determining and the second data, in query metadataThe corresponding relation of record, the bank bit of the data block that obtains storing the second data in the data file of determiningPut information; According to the stored position information obtaining, read the second data from corresponding data block, and inform KVMThe domestic os of virtual machine.
For example, comprise positional information, the data literary composition of data file 1 when the metadata in metadata information fileWhen the positional information of the positional information of part 2, the positional information of data file 3 and data file 4, according toThe mark of the data that record in the position relationship table of the mark query metadata of two data, the position of data fileWhen corresponding relation between information, the stored position information of data block in this data file, can be depositedStore up the positional information of the data file of these the second data, be assumed to be positional information, the data literary composition of data file 1The positional information of part 2, according to the positional information of the positional information of data file 1, data file 2, from numberAccording to determining a spendable data file in file 1 and data file 2, as worked as data file 1 and dataWhen file 2 does not all damage, can select data file 1 or data file 2, when data file 1 occursWhen damage, can only select data file 2. Further, according to the position letter of the data file 2 of determiningThe mark of breath and the second data, the mark of the data that record in the position relationship table of query metadata, data literary compositionCorresponding relation between positional information, the stored position information of data block in this data file of part, obtainsThe stored position information of the data block of storing these the second data in data file 2, afterwards, can be according to thisStored position information reads the second data from this data block of data file 2.
Based on technique scheme, in the embodiment of the present invention, in data writing process, can be directly by numberWrite in number of data file according to being written to the data that metadata information file comprises, in data fileWhen data writing, realize data real time backup, can in the running of KVM virtual machine, carry out,Do not need to close KVM virtual machine, backup mode is flexibility and reliability more, and the redundancy backup of supported data increasesThe security of data backup. And, by separate metadata message file and multiple data file, canContent in data file is backed up separately.
