[Pvfs2-developers] server shutdown

[Murali Vilayannur]

Hi Sam,
Sorry I did not notice this thread.
I think we should process the unprocessed requests before we have the
server exit. Server shutdown is not the only reason we have to deal with
here. If the server exits with a segfault or bus error or any other
unclean error, we don't want to be left with a corrupted volume!
I just got bitten by it recently and I have a corrupted volume that even
fsck refuses to fix (I havent dug deep enough yet).
Thanks,
Murali
