Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings.
A method for managing and alarming capacity of a storage pool as shown in fig. 1 comprises:
the state of the storage pool disk is divided into an online state, a read-only state and an offline state according to the relationship between the usage capacity and the total capacity of the storage pool and the state of the disk.
And creating a storage pool, performing state definition of the storage pool disk and establishing a state transition rule. When all the disks in the storage pool are online and the data space is not full, the pool is in an online state, and data can be written in or read out; when all the disks in the storage pool are online and the data space is exhausted, the pool is changed into a read-only state, only the data in the pool can be read, and the data cannot be written, if the data is continuously written, the data can be written into an OP space, so that no space is available during garbage recovery. When the storage pool is in a read-only state, data is expanded or deleted, and the pool is in an online state. When one disk in the storage pool is offline, the storage pool is also offline, and data cannot be read or written at the time. When the offline disk comes back online, the storage pool returns to its original state (online or read-only).
And performing state conversion on the state of the storage pool disk according to the state of the current storage pool disk and the full/exhausted data space state, and performing capacity expansion/data deletion on the storage pool disk and converting the storage pool disk into an online state when the storage pool disk is in a read-only state.
When the storage pool disk is in a read-only state, a dynamic capacity alarm threshold value is set, the used capacity is monitored, an alarm signal is sent out in time, and the distance between the used capacity and the dynamic capacity alarm threshold value is in negative correlation with the writing speed.
Specifically, a capacity alarm threshold value is set, and the storage pool monitors the used capacity when passing online and sends out an alarm signal in time. Two default exhaustion alarm thresholds are arranged in the system to which the storage pool belongs, and the dynamic capacity threshold dynamically changes according to the writing speed on the basis of the three fixed capacity thresholds, meets the alarm condition and sends out alarm signals of different levels.
Wherein the timely sending out of the alarm signal for the monitoring of the usage capacity of the storage pool comprises the following steps:
user setting of fixed threshold Tf0The default capacity threshold of the system is:
Tf1=90%
Tf2=98%
thus, three alarms are provided, one is the capacity alarm set by the user, and the other is the default capacity exhaustion alarm of the system;
reading the writing speed in the current storage pool, and calculating a dynamic threshold value:
Ta=Tf-αVw
wherein T isfIs a set fixed threshold value, TaIs the calculated current dynamic threshold, α is the transform coefficient, VwIs the writing IO speed, which is the middle value of the writing speed of the latest n times of reading, n is an odd number, and is generally 5;
calculating the capacity monitoring frequency according to the writing IO speed in the storage pool and the distance from the current used capacity to the threshold value:
β, Vw、TaT represents an adjusting coefficient, a current writing IO speed, a current dynamic threshold value and a current using capacity respectively; according to the formula, when the IO writing speed is high or the current used capacity is closer to the threshold value, the capacity monitoring frequency is very high so as to timely monitor the time when the used capacity exceeds the alarm threshold value and send an alarm signal; when the write IO speed is slow or the currently used capacity is far from the threshold, the capacity monitoring frequency becomes low because it is not necessary to consume too much computing resources to monitor frequently.
Entering a capacity monitoring function according to the calculated monitoring frequency, comparing the relation between the current use capacity and the current dynamic threshold value, and sending an alarm signal if the current use capacity is greater than or equal to the current dynamic threshold value;
when T is more than or equal to Tf0Sending out a threshold alarm signal; when T is more than or equal to Tf1Sending out a general alarm of capacity exhaustion; when T is more than or equal to Tf2And sending out a capacity exhaustion emergency alarm.
Correspondingly, as shown in fig. 2, the present invention also discloses a system for managing and alarming the capacity of a storage pool, which comprises:
the storage pool setting unit is used for dividing the storage pool into an online state, a read-only state and an offline state according to the relationship between the use capacity and the total capacity and the state of the disk;
