Specific embodiment
In order to be clearer and more clear technical problems, technical solutions and advantages to be solved, tie below
Drawings and examples are closed, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only
To explain the present invention, it is not intended to limit the present invention.
First embodiment
Before illustrating the present embodiment, user experience is disagreeableness when below in conjunction with Fig. 1 to storage pool or abnormal volume is asked
Topic is described in detail:
In Ceph storage cluster, physical memory resources carry out resource management and offer by way of storage pool (pool)
Physical resource can uniformly be carried out pondization management well in this way and flexibly control Resource allocation and smoothing by storage service.Storage
The composition unit in pond is PG (Placement Group, placement group).As shown in Figure 1, the storage of data can be first from File Mapping
To PG, OSD then is mapped to from PG again
(Object-based Storage Device, object-based storage equipment), uses PG as middle layer, can
Preferably to manage the brings Data Migration such as data balancing and data recovery, organization data also can be preferably organized.It is stored in Ceph
In cluster, PG is stateful, but storage pool is that state can not felt when client accesses to storage pool
Know the state of storage pool.If storage pool is in down state, the access request of client can be constantly in suspension status
It can not return, until storage pool restores normal.There is also the same problems for access volume (image), user when access volume,
The metadata object (i.e. header object) of access volume can be first removed, and accesses metadata object, it is necessary to first find metadata object
Then the PG at place passes through CRUSH (Controlled Replication Under Scalable Hashing, expansible Kazakhstan
Controllable replication strategy under uncommon algorithm) it is calculated which OSD PG is mapped to, so that the real carrying for finding metadata object is set
Standby, accessing other data objects is also identical process.If currently roll up it is unavailable (i.e. volume in some objects where PG not
Can use), then the access of the volume can also be constantly in suspension status, if written document writes half and then is at suspension at this time
State, user will feel very puzzled.
Above-mentioned mechanism influences user experience very much in actual use: user can not actively obtain the shape of storage pool
State leads to not flexibly be handled for the case where different conditions；Suspension status can not be immediately by resource reclaim, if request
There are many quantity, and vast resources is be easy to cause to waste.
Based on above-mentioned mechanism there are the problem of, as shown in Fig. 2, first embodiment of the invention provides a kind of data processing side
Method, the method includes the steps:
S11, the data operation request for obtaining storage system.
In the present embodiment, the memory system data includes storage pool data or volume data.
As illustratively, the operation requests of storage pool data can be creation, deletion, inquiry etc., roll up the operation of data
Request can be reading and writing etc..
S12, the corresponding placement group state of the detection memory system data.
It please refers to shown in Fig. 3, it is in one embodiment, described to detect the corresponding placement group shape of the memory system data
State comprising steps of
S121, placement group and its state all in the storage system are collected；
In this embodiment, all placements for the carrying that all OSD are reported can be obtained by management service (Manager)
Group and its state.
S122, the placement group state according to collection, filter out not available placement group；
The not available placement group that S123, basis filter out, determines the corresponding placement group state of the memory system data.
S13, according to the corresponding placement group state of the memory system data, it is determined whether by the data operation request into
Row issues.
In the present embodiment, described according to the corresponding placement group state of the memory system data, it is determined whether will be described
Data operation request issued comprising steps of
If the corresponding placement group state of the memory system data is available mode, the data operation request is carried out
It issues；
If the corresponding placement group state of the memory system data is down state, returns to the data manipulation and ask
It asks.
In the present embodiment, described to return to the data operation request comprising steps of returning to warning information；Wherein, described
Warning information includes the not available information of placement group.
In the present embodiment, user is notified by way of alarm, improves user's body while enhancing O&M
It tests.
As illustratively, in order to preferably illustrate the present embodiment, below to the operating process of storage pool data and volume data
It is illustrated:
It, will not be immediately after user issues the operation requests (such as creation, deletion, inquiry storage pool etc.) of storage pool data
This request is issued, but can first trigger the detection of a storage pool state；Storage pool state-detection relies on currently to be detected deposit
All composition PG and state of reservoir；The request of PG state-detection is received, the screening of PG state can be triggered, by abnormal PG shape
State screens, and can accelerate the comparison of PG state；The operation of screening PG state can trigger all PG states of current storage pool
It collects, this process collected mainly is asked for MGR (Manager, management service) client；MGR client receives PG shape
The request that state is asked for will send a request, to MGR to obtain the status information of correlation PG；MGR receives MGR client
After request, triggering can be gone once to ask for the request of PG status information to all OSD, to obtain current newest PG status information；
After OSD receives the request of MGR, the newest status information for being carried on all PG on one's body can be supplied to MGR.
After user issues the operation requests (such as reading and writing image data etc.) of image, this will not be requested down immediately
Hair, but can first trigger a detection that image current operation object data corresponds to PG state；Check current operation metadata pair
As corresponding PG state, the screening of a PG state can be first triggered, sees whether the PG is to belong to down state；Receive PG state
The request of detection can trigger the screening stage for carrying out PG state, and abnormal PG system states filter is come out, PG state can be accelerated
It compares；The operation of screening PG state can trigger the collections of all PG states of current storage pool, this process collected be mainly to
MGR client is asked for；MGR client receives the request that PG state is asked for, and just will create a request, to obtain the shape of correlation PG
State information；After MGR receives the request of MGR client, triggering can be gone once to ask for the request of PG status information to all OSD, with
Obtain current newest PG status information；After OSD receives the request of MGR, it can will be carried on the newest of all PG on one's body
Status information is supplied to MGR.
The data processing method of the embodiment of the present invention, the state of the placement group based on Ceph cluster decide whether to store
Pond or the operation requests for rolling up data are issued；Solve the problems, such as that user experience is disagreeableness when storage pool or abnormal volume；
The unnecessary consumption for avoiding storage pool or volume data access suspension status, resource under abnormal conditions, enhances maintainability.
