[jira] [Commented] (IGNITE-3400) IGFS: Does not correctly deallocate free space in courner case.

["Taras Ledkov (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IGNITE-3400?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15469599#comment-15469599 ] 

Taras Ledkov commented on IGNITE-3400:
--------------------------------------

{{[IgfsDataManager.processPartialBlockWrite|https://github.com/gridgain/apache-ignite/blob/sprint-2/modules/core/src/main/java/org/apache/ignite/internal/processors/igfs/IgfsDataManager.java#L1081]}} completes the future if the size limit is exceeded. Then the *format()* method doesn't remove entries of this file from the data cache.

When the feature completion is normal and the completion with {{IgfsOutOfSpaceException}} doesn't work the clean up works properly.

I heard that the limits logic will be redesigned soon. Should the issue is fixed now or with limits redesign?

> 3) Copy to IGFS file with size more than free space size.
>   Second file have 0 size in IGFS. Used IGFS size approximately equal to the IGFS space size.
> 4) Copy to IGFS file with size less than expected IGFS free space size. (f.e. 10-15 Mb)
>   New file have 0 size.
> 5) Remove all files of format IGFS
