hi,everyone
recently i am fetching about 10m pages with 7 PC cluster, after running for
two days,
one of them died. Here is the error message, it shows that the file system of
it turned to be Read-only suddenly.
before reboot it, I can ping it successfully, but I cannot ssh it. when i
connect a monitor to it, the screen is badly white.
so i think maybe the computer is somewhat crashed. if you have encountered the
same error or you have some clue on it
please let me know, thank you very much.
