In an implementation, reconstruction can judge that script is pre-stored in memory node, monitor when memory node described in
OSD is when in an abnormal state, and the reconstruction prestored can be called to judge that script determines whether to rebuild the OSD.Specifically,
The memory node, which can determine, whether there is the object stored in the form of only existing copy in the disk of the OSD, if it does not exist, then
It determines that the OSD meets the reconstruction condition, otherwise determines that the OSD is unsatisfactory for the reconstruction condition.Wherein, only existing copy refers to only
The storage object being present in the disk of an available OSD, if there are the only existing copy of storage object in the disk of exception OSD,
And OSD is rebuild, will cause loss of data, so needing to judge whether deposit in OSD to be reconstructed during OSD is rebuild
In only existing copy.
It, can be by checking PG when in the disk for judging the OSD with the presence or absence of the object stored in the form of only existing copy
(Placement Group, put in order group) state is judged.PG is the basic unit for forming storage pool, each storage object meeting
Fixation is mapped in a PG, and PG is similar to the index in database.Since there are OSD copy, the same storage object may
It is stored in the disk of multiple OSD.It, can basis when whether there is the only existing copy of storage object in the disk for judging current OSD
The copy state of the corresponding PG of each storage object determines whether the storage object only remains the copy of next available mode, if
It is to illustrate that the storage object is only existing copy, and there are the only existing copy of storage object in the disk of determining current OSD, current OSD is unsatisfactory for
Reconstruction condition.Optionally, OSD, which rebuilds condition, may further specify that the minimum number of copies magnitude of storage object, deposit when in the disk of OSD
When storing up the remaining copy amount of object less than the minimum value, illustrate that current OSD is unsatisfactory for reconstruction condition.
