Well, this is the first hours of monday, and, as promised, I have some news: after reinstalling my system with an internal NTFS partition, a panic occured when trying to copy a lot of files, small and large test random-content files (no dir structure, only files), with rsync.
The rsync command was: rsync -rltgoDuvh /mnt /var/dataholder/data_backup And there was a panic! The cpdup command was: cpdup -vvvvI /mnt/. /var/dataholder/data_backup ... and this just froze the system again, after coping 12GB of 69GB total. Ah! That is in time to say that all thee tests were made with: mount_ntfs -u raitech -g users /dev/source /dest. And the copy commands issued as a normal user. Tryied with: rsync -rltgoDuvh /mnt/* /var/dataholder/data_backup AND mount_ntfs -u raitech -g users /dev/source /dest SAME PANIC rsync -rltgoDuvh /mnt/* /var/dataholder/data_backup AND mount_ntfs /dev/source /dest SAME PANIC Here is a partial copy of the PANIC on a core.txt file: Mon Jun 25 02:47:09 BRT 2012 Version String: DragonFly v3.0.2.60.g00275d-RELEASE #0: Sun Jun 24 22:21:36 BRT 2012 root@:/usr/obj/usr/src/sys/X86_64_GENERIC panic: bgetvp - overlapping buffer GNU gdb (GDB) 7.3 Copyright (C) 2011 Free Software Foundation, Inc.
