Detailed Description
Exemplary embodiments of the present disclosure are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present disclosure to facilitate understanding, and should be considered as merely exemplary. Accordingly, one of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
As shown in fig. 1, the present disclosure relates to a mirror image making method, which may include the steps of:
s101: determining attribute information of at least one target partition by using external equipment; the target partition is a partition in which a system file is stored on the target disk; the attribute information includes partition capacity information and partition path information; the system files are files required by the operation of the operating system;
s102: creating a temporary mirror image file according to the attribute information;
s103: copying the system file to a designated directory in the temporary image file to generate a target image file.
The embodiment is suitable for external equipment of a computer, and the external equipment can be equipment comprising a system interface of a pre-starting environment. For example, an external USB flash disk running a UEFI system interface (Unified Extensible Fimware Interface, unified extensible firmware interface) may be used.
Before executing S101, the external device is plugged onto the target computing device, so that the external device is connected with the target computing device. The target computing device is a bare metal server provided with an active system file, and the external device is utilized to identify, analyze, copy and the like the active system file in the target computing device, so as to manufacture an image file corresponding to the active system, namely a target image file.
After plugging the external equipment into the target computing equipment, determining attribute information of at least one target partition by utilizing the external equipment; the target partition is a partition in which a system file is stored on the target disk; the attribute information includes partition capacity information and partition path information; the system files are files required for the operating system to run. The external device stores a disk partition (DiskPart) tool, and can manage a disk, partition or volume by directly inputting a script or a command prompt. The DiskPart tool can acquire any object in the target disk through the disk path through packaging a preset tool library of python, and further acquire attribute information of the target partition. The attribute information includes key information such as start and stop blocks, partition labels, partition names, uuid and the like of each partition. The object of the target disk may be a system file stored in advance on the target disk, which is not limited in particular.
After determining the attribute information of the target partition, executing step S102, and creating a temporary image file according to the attribute information; the temporary image file includes directory information corresponding to the partition path information. Specifically, firstly, the memory size occupied by the temporary image file can be determined according to the attribute information of the target partition, and secondly, the directory structure of the temporary image file can be determined according to the partition path information of the target partition.
Then, step S103 is executed to copy the system file to the specified directory in the temporary image file, and generate the target image file. Specifically, the system file may be copied by mounting the network block device with the temporary image file. Other ways of copying are possible as desired, without limitation.
Through the above process, the external equipment is utilized to determine the attribute information of at least one target partition, then the temporary mirror image file is created based on the attribute information, and the system file is copied to generate the target mirror image file. The method can create the image file according to the appointed partition requirement, so as to solve the problem of overlarge image file caused in the whole disk copying process and realize the technical effect of saving the storage space.
As shown in fig. 2, in one embodiment, determining attribute information of at least one target partition using an external device includes:
s201: detecting a target disk by using external equipment to generate a disk information dictionary; the disk information dictionary comprises at least one partition and label information corresponding to each partition;
s202: determining at least one target partition according to label information in the disk information dictionary; the target partition is a disk partition containing preset label information;
s203: and determining attribute information of the target partition.
The method for determining the attribute information of at least one target partition by using the external equipment can be realized by using a system partition tool in the external equipment to carry out full disk traversal, screening and detection on the target disk and generating a disk information dictionary of the target disk. The disk information dictionary may be a data structure including all files and corresponding partition paths. Specifically, the disk information dictionary may include at least one partition and tag information corresponding to each partition. The form of the disk information dictionary may be determined according to the need, for example, may be a database table structure, a key-value structure, or a nested structure of a database and a key-value, which is not limited herein.
And determining at least one target partition according to the label information in the disk information dictionary, wherein the target partition is a disk partition containing preset label information. The determination of the target partition may be accomplished by first traversing all the data records in the disk information dictionary. And then calling a labeled object searching method (find_labeled_part) in the DiskPart tool to search a partition path labeled with a preset label. The preset label is a label marked when the target disk is installed in the system, or a label marked when a user uses the target disk, which is not limited herein. The preset label can be set according to the requirement. For example, the target partition may be a partition or partitions on the target disk, without limitation. For example, the partition on the target disk storing the system file has a/dev/sdb 1 partition and a/dev/sdb 2 partition, where/dev/sdb 1 partition is labeled with an MKFS_ESP and/dev/sdb 2 is labeled with an img-rootfs. Through the find_delayed_part method in the DiskPart tool, the MKFS_ESP label and the img-rootfs label can be positioned, and then the/dev/sdb 1 partition and the/dev/sdb 2 partition corresponding to the label, namely the target partition, can be determined.
After the target partition is determined, step S203 is performed, i.e., attribute information of the target partition is determined. Specifically, the implementation manner of determining the attribute information may be to determine all detailed information related to the target partition by using an all_partition_info method of the diskport object, including: partition number (partition_number), partition length (length), partition liveness (active), partition type (type), partition name (name), partition label (label), and the like.
Through the above process, the attribute information of the target partition can be determined, so that the size of the target image file manufactured according to the attribute information can be accurately controlled.
As shown in fig. 3, in one embodiment, creating a temporary image file according to attribute information of a target partition includes:
s301: creating a blank mirror image file according to the partition capacity information;
s302: and carrying out partition processing on the blank mirror image file according to the partition path information to obtain a temporary mirror image file.
The implementation manner of creating the blank image file may be to call the partition capacity information by creating a disk file command, and generate the blank image file in img format according to the partition capacity information. Specifically, one sparse file may be created by a truncate command (create disk file command) and then converted into a blank image file in img format. The sparse file is a file storage mode in a file system, and continuous storage space required by the file is allocated to the sparse file in advance when the sparse file is created. For example, the partition capacity information of the target partition is 20 Gigabytes (GB), and by determining the sector start point and the sector end point, one 20G contiguous memory space is allocated in advance for creating a blank image file.
And carrying out partition processing on the blank mirror image file according to the partition path information to obtain a temporary mirror image file. Specifically, the partition function can be automatically called to perform partition processing on the blank mirror image file, so that the blank mirror image file containing the target partition path information is obtained. For example, a temporary image file may be created from a blank image file by creating a/dev/sdb 1 partition and a/dev/sdb 2 partition.
As shown in fig. 4, in one embodiment, creating a blank image file according to partition capacity information includes:
s401: determining the size of a blank mirror image file according to the capacity information of the target partition and the reserved capacity information; the reserved capacity information is used for representing the disk capacity occupied by the system files at the head and tail of the disk;
s402: and creating the blank image file according to the size of the blank image file.
The size of the blank image file may be determined by adding the capacity of the target partition and the reserved capacity to be the size of the blank image file. Specifically, firstly, the capacity information of the target partition is determined, specifically, a path (path) and a length (length) of the partition/dev/sdb 1 and the partition/dev/sdb 2 in the DiskPart tool are determined by using an all_partition_info method, the lengths of the two target partitions are added, and the reserved space of the head and the tail of the target disk is added, so that the size of the blank image file to be created can be calculated. The reserved capacity of the target disk can be obtained through a get (sector_size) method in the diskpoint tool. For example, the length of the/dev/sdb 1 partition is 15G, the length of the/dev/sdb 2 partition is 10G, and the reserved space acquired by the call get (sector_size) method to the head and tail of the target disk is 5G, so that the size of the computed blank image file is: 15 g+10g+5g=30g.
And creating the blank image file according to the determined size of the blank image file.
Through the above process, the blank image file can be created by calculating the sum of the capacities of the target partitions and the reserved capacity, so that redundant partitions are prevented from being added in the process of creating the image file, and the memory space occupied by the image file is reduced.
In one embodiment, the partitioning of the blank mirror file according to the partition path information includes:
mounting the network block equipment on the blank mirror image file;
directory information corresponding to the partition path information is created in the network block device, and the creation result is used as a temporary image file.
Wherein by mounting the network block device (network block device, nbd) to the blank image file, the blank image file can be entered based on nbd and loaded. Before loading the blank image file, whether the blank image file is successfully virtualized into the network block device can be judged. If the failure occurs, the error reason is checked and reloaded. Only after the network block device virtualization is successful, directory information corresponding to the partition path information is created in nbd. For example, a catalog corresponding to the/dev/sdb 1 partition and the/dev/sdb 2 partition is created in the nbd, the starting point and length of occupied memory under the corresponding catalog are consistent with the target partition, and the creation result is used as a temporary image file.
In one embodiment, after generating the target image file, the method further includes:
removing the mounting of the network block equipment and the target image file;
and converting the target image file after the mounting is removed into an image file in a preset format.
Specifically, after the partition is created in the nbd, the partition table of the nbd device can be repaired first, and then the network block device and the target image file are removed from the mount. After the mounting is removed, the target image file is converted into an image file in a preset format. Specifically, the target image file may be first compressed and converted into an image file in a preset format. The preset format may be a qcow2 format file, or may be other formats, which are not limited herein. The target image file in the preset format is then copied to the remote path and its checksum (checksum) is calculated. And finally, clearing the junk files and the related directory information, and completing the manufacture of the target image file.
