Detailed Description
In order to make the technical solutions of the present application better understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the 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 application.
The traditional information prompting method is to generate log alarm in the storage system to remind the user to check the storage pool use condition in time. However, since the user does not operate the storage system frequently, the user is difficult to view the alarm log of the storage system in time, and once the user cannot view the alarm log in time, the user cannot expand the storage pool in time, which causes the storage system to be offline and causes service interruption due to the capacity of the storage pool being used up.
Therefore, the embodiment of the present application provides an information prompting method, which enables a user to view an alarm log at a target host side in time by generating the alarm log at the target host side corresponding to a target server, so as to prompt the user to expand a storage pool in time, avoid a storage system being offline due to the capacity of the storage pool being used up, and ensure service continuity.
Next, an information presentation method provided by an embodiment of the present application will be described with reference to the drawings. Referring to fig. 1, the method includes:
s101, aiming at any one target server in a plurality of servers, acquiring the actual use capacity of the target automatic thin volume corresponding to the target server.
The method is applied to a storage system, the storage system is connected with a plurality of servers, each server is provided with a corresponding thin auto-matically, and the preset capacity of each thin auto-matically is preset.
In the storage system, the storage system and the plurality of servers may be connected by optical fiber links, the preset capacity of the thin auto volume of each server may be set according to the service requirement of the service provided by the server, and the preset capacities of different servers may be the same or different.
When capacity is actually allocated to the thin provisioning volume of the server, the preset capacity may be allocated for multiple times, that is, when capacity is allocated to the thin provisioning volume of the server for the first time, the preset capacity may be allocated according to a preset proportion of the preset capacity, and each subsequent allocation expands the previous thin provisioning volume according to a corresponding capacity size. The size of the capacity for each expansion may be a fixed value or a variable value.
For example, the preset capacity of the thin volume of the server a is 500G, when the capacity is allocated to the thin volume of the server for the first time, the thin volume may be allocated according to a preset proportion of the preset capacity, where the preset proportion is, for example, 2%, if each subsequent allocation expands the previous thin volume according to a fixed value of 5G, the thin volume of the server may be allocated with 5G capacity for the second time, so as to expand the thin volume after the first allocation, and so on.
The multiple servers may include different system versions, such as reddat and windows, etc.
In this embodiment, a certain capacity may be previously divided for the storage pools in the storage system, and the capacities allocated to the servers in the storage system are all from the storage pools.
And S102, if the actual use capacity reaches a target alarm threshold value, generating an alarm log at a target host end corresponding to the target server.
The target alarm threshold is configured at the target host according to the preset capacity of the target thin provisioning volume and the capacity of the storage pool. The target alarm thresholds of different target servers may be the same or different. The target alarm threshold may be a capacity value or a percentage of a preset capacity of the target thin provisioning volume.
If the actual usage capacity of each target server reaches the target alarm threshold, it indicates that the sum of the actual usage capacities of the target servers will approach the capacity of the storage pool. In order to avoid the capacity of the storage pool being used up, when the actually used capacity reaches a target alarm threshold, an alarm log may be generated at a target host corresponding to the target server to remind a user to expand the capacity of the storage pool.
For example, the storage system is connected to two servers, the preset capacity of the thin provisioning volumes corresponding to the two servers is 500G, the capacity of the storage pool is 800G, and if a target alarm threshold is set to 60% for any target server of the two servers, that is, if the actual usage capacity of the target thin provisioning volume corresponding to the target server reaches 500 × 60% — 300G, an alarm log is generated at the target host corresponding to the target server.
Generally, when a target alarm threshold is set, it should be ensured that the target alarm threshold is smaller than the preset capacity of the target thin provisioning volume, and the sum of the target alarm thresholds respectively corresponding to all the target servers is smaller than the capacity of the storage pool.
The method is applied to a storage system, the storage system is connected with a plurality of servers, each server is provided with a corresponding thin provisioning volume, the preset capacity of each thin provisioning volume is preset, and a target alarm threshold value is configured for a target thin provisioning volume at a target host terminal according to the preset capacity of the target thin provisioning volume and the capacity of a storage pool aiming at any one target server in the plurality of servers. In the process that a target server uses the capacity of an automatic thin volume, acquiring the actual use capacity of the target automatic thin volume corresponding to the target server; and if the actual use capacity reaches a target alarm threshold value, generating an alarm log at a target host end corresponding to the target server. The alarm log is generated at the target host side, the target host side is user-oriented, and the user can often operate at the target host side, so that the user can timely check the alarm log at the target host side through the method, the user is timely reminded of expanding the storage pool, the storage system is prevented from being off-line due to the fact that the capacity of the storage pool is used up, and the service continuity is guaranteed.
Optionally, the target alarm threshold is configured at the target host according to a preset capacity of the target thin provisioning volume, a capacity of the storage pool, and a service priority of the target server.
It can be understood that, the higher the service priority, the higher the capacity of the storage pool can be preferentially allocated to the target server, at this time, the target alarm threshold of the target server can be set to be larger, and conversely, the target alarm threshold of the target server can be set to be smaller.
Optionally, if the actual usage capacity reaches the target alarm threshold, the method further includes generating an alarm log in the storage system, so that the user is reminded at the target host side and the storage system at the same time.
Optionally, the target alarm threshold is configured according to the system version of the target server, and the target alarm thresholds of the target servers of different system versions are configured in different manners.
Next, the configuration of the target alarm threshold will be described by taking the target servers of which the system versions are Redhat and windows, respectively, as examples.

Scanning all user quotas (usrquota).
Scanning all group quotas (grpquota).
(5) QUOTA is initiated by: (wherein, quotoon is on and quotoff is off)
[root@localhost/]#quotaon-avug
/dev/sdb1[/dvd]:group quotas turned on
/dev/sdb1[/dvd]:user quotas turned on
Turn on all quota settings, according to/etc/mtab settings.
V information is displayed when quota is turned on.
(6) The user is edited by the following commands, configuring the target alarm threshold:
[ root @ localhost/] # useradd redhatat- - - - - > building a common user redhatat
[root@localhost/]#edquota-u redhat

Filesystem blocks soft hard inodes soft hard
/dev/sdb1 0 300000000 0 0 0 0
(7) Enabling target alarm threshold functionality
[root@localhost/]#quotaon-ugv/dvd/
/dev/sdb1[/dvd]:group quotas turned on
/dev/sdb1[/dvd]:user quotas turned on
[ root @ localhost/] # chmod o + w/dvd- - - - - - - - - - - - - -/dvd right is modified, and other users can set a target alarm threshold value.
The target server with the system version of windows mainly configures a target alarm threshold value in a mode of setting in an operation interface of a user. If the preset capacities of the target thin provisioning volumes corresponding to the target server are all 500G, the capacity of the storage pool is 800G, and the target alarm threshold is set to be 500 × 60% — 300G, the target alarm threshold configuration process is as follows:
