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. Pete
