Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The following explains key terms appearing in the present invention.
Linux: the GNU/Linux is a free-use and free-propagation UNIX-like operating system, the kernel of which is released for the first time in 1991 by Linnas Benne Kett Towaz, and the operating system is mainly inspired by Minix and Unix ideas and is a multi-user, multi-task, multi-thread and multi-CPU supporting operating system based on POSIX and Unix. It can run major Unix tool software, applications, and network protocols. It supports 32-bit and 64-bit hardware. Linux inherits the design idea of Unix with network as core, and is a multi-user network operating system with stable performance. There are hundreds of different releases for Linux, such as debian, archlinux based on community development, and Red Hat Enterprise Linux, SUSE, oracle Linux based on commercial development, etc.
And (3) system partitioning: the partitions necessary for installing and running the Linux system can be generally divided into:
root directory for storing system commands and user data
Static link file of/boot loader, storing program related to Linux startup
A home user directory for storing data of common users
/tmp temporary file
/usr is the place for storing software in Red Hat Linux system
The/usr/local self-installed program is installed in the device
The data that is constantly changing by/var, some services of the server are put below.
Opt-attached application software package
/Swap switching area
Data partitioning: the partitions, except the system, are generally used for business data storage.
And (3) partition checking: the Linux file system may be damaged in various situations, such as a system crash, a sudden power failure, a disk disconnection, or an inadvertent overwriting of a file node (i-node), etc., and thus needs to check the file system.
And (3) repairing partitions: and repairing the partition by using a file system repairing tool, and correcting the abnormal state. However, due to insufficient system resources, such as insufficient memory capacity, the success rate of repair can be improved by capacity expansion (memory or swap partition).
A Swap partition: when the physical memory of the system is insufficient, the system exchanges with the Swap, and breaks through the limitation of the physical memory in function.
Quota (quota): the use amount of the user (user group) to the disk space is limited, and under the NAS sharing use mode, a plurality of user sharing partitions exist, so that the situation that a certain user excessively uses the disk space and other clients have no space to use is avoided. The available quota specifies the maximum available space for a user (user group).
FIG. 1 is a schematic flow diagram of a method of one embodiment of the invention. The execution subject in fig. 1 may be a system for mounting a data partition.
As shown in fig. 1, the method includes:

Specifically, taking the wave AS1500G2 data partition starting AS an example, the method for mounting the data partition includes:
s1, disabling automatic mounting of the partition system:
cp/etc/mtab/etc/mtab.bak.$date
echo“”>/etc/mtab
s2, acquiring a data partition list by using a cat instruction: cat/dev/iom _ block. The cat command is used to link files and print to standard output devices.
S3, checking the file system state based on the data partition list:
xfs_repair_adm-C/dev/iom_block_834。
the file system checking function is a self-contained function of the linux operating system, namely, each partition in a data partition list is traversed, and when the space of a certain partition is insufficient or a file is abnormal, the file is displayed in a checking result.
S4, repair file system xfs _ repair _ adm-l/dev/iom _ block _834
And starting a file system repair process of the linux system and executing file system repair.
S5, when the repair fails, the hot spare disk is cancelled, the swap partition of the mkswap capacity expansion system is executed, then the swap analysis is started by executing the swap command, and then the file system is repaired:
idisk-s＝0/dev/vd-sdy
mkswap/dev/vd-sdy
swapon/dev/sdy
xfs_repair_adm-l/dev/iom_block_834。
when the physical memory of the system is not enough, the Swap partition releases a part of the space in the hard disk memory for the current running program to use. The freed space may come from programs that have not operated for a long time, is temporarily saved to the Swap partition, and the saved data is restored from the Swap partition to memory until the programs are run.
S6, completing the repair of the xfs _ repair _ adm, and executing mount partition of mount command
mkdir-p/fs/vg150803-data1
mount-o usrquota,grpquota-t xfs/dev/iom_block_834/fs/vg150803-data1。
S7, enabling upper application/etc/init.d/nfs restart.
S8, using swap off to stop expanded swap partition, and restoring hard disk to hot standby state
swapoff/dev/vd-sdy
idisk--global-s＝1/dev/vd-sdy。
