Re: Input/output error when files in .shard folder are deleted

I did one random read test (~10k shard in one replicate group) but so
far no error reported, will try to do few more tests over the weekend
to confirm this.

Just a quick question, is the full heal process heal in sequence
according to sorted file name?

Thanks.
