No, I did not use it, but I was thinking about and ran the script from http://sandeen.net/misc/summarise_stat.pl and got as an example on /bin: # /net/c3m/usr/local/software/XFS/summarise_stat.pl /bin/ 9 6.2% are scripts (shell, perl, whatever) 65 44.8% don't use any stat() family calls at all 61 42.1% use 32-bit stat() family interfaces only 9 6.2% use 64-bit stat64() family interfaces only 1 0.7% use both 32-bit and 64-bit stat() family interfaces So I was not sure if I should use inode64 or not. This are the times that the run took yesterday: Mon Feb 13 19:14:07 CET 2012 + wc -l + find 2012-02-13/ 11377443 real 101m30.811s user 0m17.365s sys 1m4.632s Mon Feb 13 20:55:38 CET 2012 + wc -l + find 2012-02-13/ -type d 834591 real 103m52.686s user 0m11.765s sys 1m41.018s + wc -l + find 2012-02-13/ -type f 10539154 real 104m38.421s user 0m19.905s sys 1m47.551s + /bin/rm -i -rf 2012-02-13/ real 110m55.764s user 0m13.401s sys 4m3.115s Tue Feb 14 02:15:05 CET 2012 Thanks again, Richard -- Richard Ems mail: Richard.Ems@xxxxxxxxxxxxxxxxx Cape Horn Engineering S.L.
