> There is a low probability that the partition state restored incorrectly when
> a cache is starting with data on disk.
> The issue happened because cluster can save the partition meta page during it
> state is still restored.
> The code is shown below (GridCacheOffheapManager.java):
> {code:java}
> @Override public Map<Integer, Long> restorePartitionStates {
> //Here the metapage was restored from disk, but it state is not recovery in
> GridDhtLocalPartition.
> part.dataStore().init();
> ... // Here another thread will be able to execute saveStoreMetadata and
> set an incorrect state on the metapage.
> //State will be recovered only here.
> long pageAddr = pageMem.writeLock(grp.groupId(), partMetaId, partMetaPage);
> try {
> int stateId = io.getPartitionState(pageAddr);
> updateState(part, stateId);
> }
> finaly {
> pageMem.writeUnlock(grp.groupId(), partMetaId, partMetaPage, null,
> changed);
> }
> }
> {code}
