[PVFS-users] meta server and io servers out of sync

[Don Porter]

If you want to recover the space on the io servers, you can do that
too...

Before you delete the meta file, find its inode number.  Then, on each
of the iods (except the one that went down, of course), its data file
will be in <data directory>/<inode % 101>/f<inode#>.0 .  If you delete
this file, you will recover the space.

Good luck,
don
