> So the root cause of this error is not clear, unless file was changed
> somehow. We need extended information if such error will happen in future,
> but in this case we have nothing for analysis (LFS was cleared by the
> customer right after this error happened).
> In the same time we can’t guarantee correctness of work when checkpoint
> markers are inconsistent. We can’t just ignore them, if they are broken, and
> can’t recover from previous checkpoint just as simple.
> But it seems reasonable to catch all reading-related exceptions in
> org.apache.ignite.internal.processors.cache.persistence.checkpoint.CheckpointMarkersStorage#readPointer.
