    SubjectAntwort: Re: Kernel Hangs 2.4.16 on heay io Oracle and Tivolie TSM
    From
    Date
    Hi,

    on saturday a had a nice day with 16 houre to find a workaround to bring
    linux stable.
    I had moved the server from reiserfs to ext2 for all datafile areas. The
    move with tar
    runs without any crash. I had an about 60 to 75 MB/second transfer ( read +
    write) on the
    move of the oracle datafiles.

    After startup of oracle and backup the open datafiles ( i know this is
    nonsens but its a good stress test)
    i get a crash. On a reiserfs this would crash immediately. On ext2 crash
    happend after about 2.5houres of backup ( about 80GB datafiles).
    After this i switched backup to kernel version 2.2.19. ---> The system runs
    now without crash.
    On other server without oracle but which are have tsm backup we had no
    problems with 2.4.16 ( at the moment only about 15 Servers)

    Its seems that you are right an we have a serious vm bug. This bug is only
    viewable if you user oracle and tsm (tivoli storage manager) .... Strange.

    Kinds regards

    Oliver Schersand
