xfs_repair deletes file

[Agarwal, Amit]

Hi 

I need some help related to xfs repair. 

xfs_repair is deleting files which are more than ~10G from the real time partition.  This is happening quite frequently.

xfs_repair version 3.0.0
Linux ->  2.6.18.8

Following is the output of xfs_repair

Phase 1 - find and verify superblock...
Phase 2 - using internal log
        - zero log...
        - scan filesystem freespace and inode maps...
        - found root inode chunk
Phase 3 - for each AG...
        - scan and clear agi unlinked lists...
        - process known inodes and perform inode discovery...
        - agno = 0
        - agno = 1
data fork in rt inode 16779171 claims used rt block 16538

        - agno = 2
        - agno = 3

Phase 4 - check for duplicate blocks...
        - setting up duplicate extent list...

        - agno = 2
        - agno = 3

Phase 7 - verify and correct link counts...
done

Thanks for your time

might be best to retest on a recent kernel, as this looks like something went 
wrong at runtime.

Do you have a testcase to recreate the situation?
