Re: [Moosefs-users] Invalid copies of chunks

[Steve W. <st...@pu...>]

Hi Michal,

I've already run mfsfilerepair on the files in these chunks.  Most of 
the corrupted files are temporary files that must have been open at the 
time of the changeover.  I wouldn't mind just deleting the files, if I 
could.  Some of the files, however, give a "realpath error" when I 
attempt to run mfsfilerepair:

     mfsfilerepair /net/jiang/fguo/.cache/indicator-applet-session.log
     /net/jiang/fguo/.cache/indicator-applet-session.log: realpath error

Is there any way to clean up these chunks if mfsfilerepair fails?  
Again, I wouldn't mind losing files like the indicator-applet-session.log...

Thanks,

Steve
