>             Project: Ignite
>          Issue Type: New Feature
>          Components: persistence
>    Affects Versions: 2.8.1
>            Reporter: Sergey Chugunov
>            Assignee: Sergey Chugunov
>            Priority: Critical
>              Labels: IEP-53
>             Fix For: 2.10
>
>   Original Estimate: 168h
>          Time Spent: 1h 40m
>  Remaining Estimate: 166h 20m
>
> If node with persistence is stopped when WAL was disabled for a cache (no 
> matters because of rebalancing in progress or by explicit user request) on 
> next node start all data files of that cache are removed automatically and 
> unconditionally.
> This behavior may be unexpected for users as they may not understand all 
> consequences of disabling WAL locally (for rebalancing) or globally (via 
> IgniteCluster API call). Also it is not smart enough as there is no point in 
> deleting consistent data files.
> We should change this behavior to the following list: no automatic deletions 
> whatsoever. If data files are consistent (equivalent to: no checkpoint was 
> running when node was stopped) start up normally. If data files are 
> corrupted, don't let the node start.
