>                 URL: https://issues.apache.org/jira/browse/IGNITE-8111
>             Project: Ignite
>          Issue Type: Improvement
>    Affects Versions: 2.4
>            Reporter: Ivan Rakov
>            Assignee: Denis Garus
>            Priority: Major
>              Labels: newbie
>             Fix For: 2.5
> Currently we can set extra small DataStorageConfiguration#walSegmentSize (10 
> pages or even less than one page), which will trigger multiple assertion 
> errors in code.
> We have to implement validation on node start that WAL segment size has 
> reasonable value (512KB or more).
