Abstract
The invention discloses a cluster management method and device. The cluster management method includes the steps that a user is established according to management nodes; user information is synchronized to a node where a shared disk of clusters is located; a disk quota is set for the shared disk; the user information is synchronized to a preassigned node. Through the method, a local disk quota management strategy can be supported besides an overall disk quota management strategy, user disk quota can be set individually on an assigned node, and therefore the flexibility of a systematic management method is greatly enhanced.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain, all belongs to the scope of protection of the invention.
According to embodiments of the invention, provide a kind of cluster management method.
As shown in Figure 1, comprise according to the cluster management method of the embodiment of the present invention:
Step S101, management node creates user;
Step S103, is synchronized to the node at the shared disk place of cluster by user profile;
Step S105, arranges Disk Quotas to shared disk;
Step S107, is synchronized to preassigned node by user profile.
The global policies that above-mentioned steps can realize Disk Quotas controls and local policy control, can also comprise to strengthen flexibility of the present invention further:
From cluster, user profile is filtered out according to presetting rule;
The user profile filtered out is distributed to preassigned unenforced node in cluster, unenforced node is specify the node not needing to be configured in advance;
The user profile filtered out is write unenforced node.
And, comprise further:
From cluster, user profile is filtered out according to presetting rule;
The user profile filtered out is distributed to infirm node in cluster, infirm node is running but needing the node that termination configures;
The user profile of infirm node is deleted.
In addition, each node in cluster intercoms mutually.
In addition, user rs authentication is not needed between each node in cluster.
Technical scheme for a more clear understanding of the present invention, to be described with specific embodiment below, please refer to shown in Fig. 2, Fig. 2 shows the Disk Quotas strategy setting flow process of the present invention local or the overall situation, " preassigned node (node comprises all types) " technical terms hereinafter can be understood as the node of specifying according to the actual requirements, such as choose when needing part of nodes to be configured, or when needing all configurations select.
For local Disk Quotas strategy setting, in whole cluster, namely only need part of nodes to come into force, its flow process is as follows:
A) management node creates user;
B) user is synchronized to shared disk place node;
C) Disk Quotas is set;
D) simultaneous user is to specified node.
Be more than the step of local Disk Quotas strategy setting, when needing current local policy to upgrade to global policies, Fig. 3 shows the flow process that local policy upgrades to global policies, and its concrete steps are as follows:
A) user's associated documents are filtered out;
B) dispatch user information is to local policy Pending The Entry Into Force node;
C) be added into user file by after user profile process, avoid affecting existing local policy.
When needing current global policies to be downgraded to local policy, Fig. 4 shows the flow process that global policies is downgraded to local policy, and its step is as follows:
A) user's associated documents are filtered out;
B) dispatch user information to local policy does not come into force node;
C) delete after user profile process from user's associated documents.
In addition, during in order to ensure that cluster environment fluctuates, proper communication between node, the correct onset of Disk Quotas strategy: the present invention has the relevant information of user due to each node, in therefore running, the user rs authentication of task does not limit by network.
According to embodiments of the invention, additionally provide a kind of cluster management device, as shown in Figure 5, this device comprises:
Creation module 51, creates user for management node;
First synchronization module 52, for being synchronized to the node at the shared disk place of cluster by user profile;
