Detailed Description
It can be understood that, at present, restarting, adding a disk, removing a disk, shrinking a volume, expanding a volume, etc. after a long time of failure of an OSD may trigger a Peering (a state of a PG, which is distributed in a process of completing a synchronous state between the same PGs that do not pass through the OSD) process, and by comparing objects between the PGs of other OSDs, a missing object list is obtained, referring to fig. 1, which is a data recovery flow diagram in the existing scheme, it can be seen that, at present, the following process may be included when data recovery is performed: triggering a Peering flow to obtain a missing object list; the PG starts to enter a backlash state to recover data; during backfiltering, the PG detects whether the residual space of the OSD is smaller than a threshold value, if so, the backfiltering is stopped, otherwise, 512 object information of the missing object list is put in a recovery queue for recovery, the OSD space is not detected in the recovery process, and the next recovery is performed again until the 512 objects are recovered; and finishing the recovery of the PG when the recovery of the missing object list is finished.
In this data recovery situation, if n PGs of an OSD are simultaneously recovered, the required space is n × 512 × sizeof (object), when the object is large, the n PGs may not reach the threshold value during detection, however, the required total space is greater than the remaining space of the OSD, and at this time, the OSD is fully written by the n PGs during the recovery process, so that the OSD process is dead and cannot be recovered.
Based on the above problems, the present invention provides a data recovery method, apparatus, device and storage medium, in which the OSD partition is not fully written during data recovery, PG is effectively intercepted during the backward filtering process, and OSD full writing is prevented.
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, 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 invention.
The embodiment of the invention discloses a data recovery method, a data recovery device, data recovery equipment and a storage medium, which are used for preventing OSD fullness and avoiding OSD process downtime.
Referring to fig. 2, a schematic flow chart of a data recovery method provided in an embodiment of the present invention can be seen from fig. 1, where the method specifically includes the following steps:
s101, determining to-be-recovered data of a group;
in this embodiment, after the OSD fails for a long time, the Peering process is triggered by restarting, adding, removing, shrinking, expanding, and the like, before the PG performs data recovery, the PG needs to obtain a missing object list by comparing objects between the PGs of other OSDs, then sequentially select 512 object data from the missing object list as data to be recovered in each round, and place the data to be recovered in a recovery queue for recovery.
S102, detecting whether the residual space of the object storage equipment where the homing group is located is smaller than a threshold value;
if not, executing S103; if yes, executing S106;
it can be understood that, before data recovery, it is first required to detect whether the remaining space of the object storage device where the storage group is located is smaller than a threshold, if the remaining space of the object storage device is smaller than the threshold, it indicates that the remaining space of the current object storage device is already small, and if data recovery is performed again, normal use of the object storage device is affected, so in this case, data recovery can be directly stopped; if the residual space of the object storage device is not less than the threshold value, the subsequent flow is continuously executed.
S103, determining a target space required by data to be recovered;
in this embodiment, if the data to be restored is 512 objects, the target space is a space required for restoring 512 objects.
S104, judging whether the sum of the target space and the required total space is larger than the available space of the object storage equipment or not; wherein the required total space is: the total space required by other object storage device to restore data;
if not, executing S105; if yes, executing S106;
and S105, performing data recovery on the data to be recovered.
And S106, stopping data recovery of the reset group.
It should be noted that, after the PG starts to enter a backlilling state and data is restored, the OSD needs to initialize a required total space (needlesize) to 0, and the needlesize is used for counting and recording the required space size in the OSD restoring process; then after the residual space of the object storage equipment where the homing group is located is not less than the threshold, judging whether the sum of the target space and the required total space is greater than the available space of the object storage equipment, wherein the available space is the difference between the residual space of the object storage equipment and the threshold; if the sum of the target space and the required total space is larger than the available space of the object storage equipment, indicating that the residual space of the object storage equipment is smaller than the threshold value due to the data recovery, stopping the data recovery; on the contrary, if the sum of the target space and the required total space is not greater than the available space of the object storage device, the data recovery is performed, and the remaining space of the object storage device is not smaller than the threshold, at this time, the data recovery can be performed.
Further, in order to ensure the accuracy of the required space needlesize, the present scheme needs to update the required total space before and after data recovery, for example: updating the total space required prior to data recovery, wherein: the updated required total space is the sum of the required total space before updating and the target space required by the data to be recovered. In addition, when the data to be recovered is recovered, one of the object data in the data to be recovered is recovered each time, and after the data of one of the object data is recovered each time, the required total space needs to be updated, where: the updated required total space is a difference between the required total space before the update and the required space of the one of the object data.
Referring to fig. 3, a flowchart of a specific data recovery method provided in the embodiment of the present invention is shown, and as can be seen from fig. 3, the recovery method specifically includes the following steps: initializing the needleSize to be 0 by the OSD, triggering the Peering flow, and acquiring a missing object list; the PG starts to enter a backlash state to recover data; during backfiltering, the PG detects whether the residual space of the OSD where the PG is located is smaller than a threshold value, if so, backfiltering is stopped, otherwise, the sum T of the space required for recovering 512 objects and the needlesize is calculated, if the T is larger than the available space left when the OSD reaches the threshold value, the PG stops backfiltering, otherwise, the needlesize accumulates 512 object sizes, 512 object information of a missing object list is placed in a recovery queue for recovery, one object is recovered each time, the needlesize subtracts the object size, and the next recovery is performed again until the 512 objects are recovered; and when the recovery of the missing object list is finished, the recovery of the PG is ended.
It can be seen that, in the present solution, when a homing group recovers data, after detecting that the remaining space of an object storage device is not less than a threshold, it is further required to determine a total space required by other homing groups of the current object storage device when performing data recovery, and a sum of a target space required by the current homing group when performing data recovery, and determine whether the total space is greater than an available space of the object storage device; if the number of the storage devices is larger than the available space, the data recovery is stopped, and by the mode, when the data recovery is simultaneously performed on the plurality of the homing groups of the object storage devices, the situation that the object storage devices are full is avoided, and the problem that the OSD process is down and cannot be recovered due to the fact that the object storage devices are full is further avoided.
