Detailed Description
The embodiment of the invention provides a management method, a device, a system and a computer readable storage medium for a local user group of storage equipment, which can effectively shorten the search time, improve the search efficiency, reduce the task blocking risk and improve the system performance in the use process.
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for managing a local user group of a storage device according to an embodiment of the present invention. The method comprises the following steps:
s110: before deleting the local user group to be deleted, acquiring a backup file corresponding to a service search sequence file of the storage device before the storage device joins the domain control;
it should be noted that, in the embodiment of the present invention, the local user group to be deleted is used as the local user group to be deleted, and before the storage device is added to the domain control, the service search sequence file nsswithch. Conf of the storage device is backed up to obtain a corresponding backup file, where the backup file only includes the user information of the local user of the storage device, after the storage device is added to the domain control, the service search sequence file of the storage device is modified, that is, the user information related to the domain control is added to the service search sequence file, and if the storage device is not added to the domain control, the backup of the service search sequence file of the storage device is not required.
Specifically, before the deletion operation is performed on the local user group to be deleted of the storage device, a backup file that is backed up by searching the sequential files for services of the storage device before the storage device joins the domain control may be obtained first.
Further, before the step S110 of obtaining the backup file corresponding to the service search order file of the storage device before the storage device joins the domain control, the method may further include:
and judging whether the storage equipment is added with the domain control, if so, executing the step of acquiring the backup file corresponding to the service search sequence file of the storage equipment before the storage equipment is added with the domain control.
It can be understood that when the local user group to be deleted is to be deleted, whether the storage device has added a domain control can be judged first, and after the fact that the storage device has added a domain control is determined, the fact that the operation of backing up the service search sequence file of the storage device has been executed before the storage device has added a domain control is indicated, and the corresponding backup file exists, so that the corresponding backup file can be obtained, if the storage device has not added a domain control, the fact that the service search sequence file of the storage device is not backed up is indicated, and the service search sequence file is not modified, so that the service search sequence file of the storage device can be directly obtained before the local user group to be deleted is deleted.
Further, the above process of determining whether the storage device has joined the domain control may specifically be:
acquiring a domain control zone bit corresponding to the storage equipment;
and judging whether the storage equipment is added into the domain control according to the domain control flag bit.

S120: searching the user information in the backup file, and judging whether the users belonging to the local user group to be deleted exist or not; if not, then S130 is entered;
after the backup file is obtained, searching each piece of user information (i.e., local user information) in the backup file to determine whether user information corresponding to the local user group to be deleted exists in the pieces of user information, if so, the existence of the user belongs to the local user group to be deleted, the local user group to be deleted is in a used state, and if not, the existence of the user belonging to the local user group to be deleted is indicated, and the local user group to be deleted is in an idle state.
Specifically, the user information in the embodiment of the present invention may include a user group ID to which the user belongs; and searching each piece of user information in the backup file according to the user group ID of the local user group to be deleted so as to determine whether the user belonging to the local user group to be deleted exists, specifically, traversing each piece of user information in the backup file, and determining whether the user group ID of the user belonging to the user information is consistent with the user group ID of the local user group to be deleted or not one by one, if so, indicating that the user corresponding to the user information belongs to the local user group to be deleted, and if not, indicating that the user corresponding to the user information does not belong to the local user group to be deleted.
S130: and deleting the local user group to be deleted.
Specifically, when it is determined that there is no user corresponding to the local user group to be deleted, the local user group to be deleted may be deleted.
Therefore, in the embodiment of the invention, the service search sequence file of the storage device is backed up to obtain the backup file before the storage device is added into the domain control, then the backup file is obtained before the local user group to be deleted is deleted, and each user information in the backup file is searched to determine whether the user belonging to the local user group to be deleted exists.
