[Pvfs2-developers] Trove DBPF error

[Phil Carns]

There is actually an admin tool (pvfs2-rm-object) that does what Kevin 
described (used for testing pvfs2-fsck mainly).  That can be used to get 
rid of each handle/object in the file, but that would still leave a 
directory entry to get rid of...

Does pvfs2-rm not remove the entire file?  It may be easier to tweak 
pvfs2-rm to continue in your case (if it doesn't already) to clear it out.
