    I'm pretty sure that defragfs is in the basic AIX install. You just run 'defragfs /yourfs', and it'll defrag the FS for you. You can run it while the box is up, though it will probably place a non-negligible load on the disk.

    Not sure I see how that helps, unless as Simon has stated, since /var is pretty busy, those are spurious errors due to the fact that the filesystem was being written to when fsck was run, and you're thinking the FS is just fragmented...

    All defragfs does is compact the data and free up contiguous space on the disk.

    Boot off CD. Go to maintenance mode. Access rootvg without mount file system
    and then run fsck

    I get this:
    ----------------------------------------------------------------------------
    ------------
    $ fsck -p /dev/hd9var

    /dev/hd9var (/var): Bad Inode Map (NOT SALVAGED)
    /dev/hd9var (/var): Bad Block Map (NOT SALVAGED)
    /dev/hd9var (/var): Filesystem integrity is not guaranteed
    /dev/hd9var (/var): 458 files 20485 blocks 241659 free
    ----------------------------------------------------------------------------
    -------------
    any ideas in resolving it? TIA
