OK, i scrounged up a 15GB USB (1.0?!) external drive and was able to do the "git clone bzr::" in 7.5 hours -- woo hoo! It's somewhat tight now: $ LANG=3DC df -h . Filesystem Size Used Avail Use% Mounted on /dev/sdb1 14G 13G 794M 95% /mnt/mulo This was after two failing attempts, both ending with an error message: bzrlib.errors.GhostRevisionsHaveNoRevno: Could not determine revno for {ID-1} because its ancestry shows a ghost at {ID-2} Write failed: Broken pipe In both attempts, ID-1 was: kenner@gnu.org-19980613195110-2j7ddnyudwfyfytc ID-2 for the attempts were (respectively): dmoncayo@gmail.com-20131207130209-d61sb5r2xuww52j0 jan.h.d@swipnet.se-20131207142629-caazt8axffdl8p2o On the third (successful) attempt, the only strange output was (excerpt): progress revision 60600 'master' (60600/115406) progress revision 60700 'master' (60700/115406) Write failed: Broken pipe progress revision 60800 'master' (60800/115406) progress revision 60900 'master' (60900/115406) I hope these errors are not an indication of tampering or corruption. Next step is to snapshot this tree (somehow) and then do some local munging experiments, perhaps starting w/ "git gc --aggressive". =2D-=20 Thien-Thi Nguyen GPG key: 4C807502 (if you're human and you know it) read my lisp: (responsep (questions 'technical) (not (via 'mailing-list))) =3D> nil --=-=-= Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iEYEARECAAYFAlKkUXoACgkQZwMiJEyAdQLfLACdGVDPc2X+CHWPtqBJW1jCm1i6 dU4AoLoIPGyI0+coaz2VlyLLUc8/oDlJ =RqgR -----END PGP SIGNATURE----- --=-=-=--
