#2 2 GB dump file limit?

    Remember me? :)

    I am having another issue... one of our server has about a 3.5 GB backup, we attempt to do this via file to
    the backup server then we do the tape of all servers... however this one seems to be getting stopped at
    about 2GB, is this a limit of the e2fs?

    root@bill:~:# backup


    DUMP: Connection to ted established.
    DUMP: Date of this level 0 dump: Mon Apr 10 22:06:09 2000
    DUMP: Date of last level 0 dump: the epoch
    DUMP: Dumping /dev/hda1 (/) to /backup/bill.dump on host ted
    DUMP: Label: none
    DUMP: mapping (Pass I) [regular files]
    DUMP: mapping (Pass II) [directories]
    DUMP: estimated 3184949 tape blocks.
    DUMP: Volume 1 started at: Mon Apr 10 22:06:54 2000
    DUMP: dumping (Pass III) [directories]

    DUMP: 39.95% done, finished in 0:22
    DUMP: 54.45% done, finished in 0:16
    DUMP: write: File too large
    DUMP: write error 2097170 blocks into volume 1
    DUMP: Do you want to restart?: ("yes" or "no") no
    DUMP: The ENTIRE dump is aborted.

    --- END ---

    root@bill:~:# cat /root/bin/backup
    printf "\n\n --- START FULL BACKUP --- \n\n\n"
    /sbin/dump -0au -f ted:/backup/bill.dump /dev/hda1
    printf "\n\n --- END --- \n\n"

    I am starting to wonder whether there is a special option at boot time to allow files larger than 2 GB... In my Solaris
    boxes, the maximum file size is one terrabyte... unless you put a special option on to limit file size to 2 GB..

    The 2GB is a limit of ext2fs. You can bypass this limit by
    enabling large
    file support (but you will surely need to recompile your
    kernel, have
    a recent glibc, maybe recompile some programs... I cannot
    really help
    you with this, maybe there is a FAQ somewhere? ).

    As for this limit seen from the dump's point of view, you
    can use the -M (multivolume option) coupled with the -B (to
    specify the 2GB size of each volume).

    Hope this helps.
