    fsck requires approximately 700k memory for each gigabyte of disk space.
    I´m unfortunately not familiar enough with the issue how this splits out
    for
    blocks and inodes (for example if having only a million inodes on a 10TB fs
    would make it tolerable) but taking the figure presented earlier, you would
    need 7GB of memory for checking a 10TB filesystem. Having that kind
    of memory for a single process neccessiates a 64bit system, like sparc64,
    alpha, itanic or opteron.
