I saw a bug report about a seg fault with ncpfs that was fixed in the 3 series linux kernel. Can you test with the latest gentoo-sources, which is gentoo-sources-3.0.4 as of this writing. I tested once more with 3.0.4-gentoo. It seems that it works now: root@moose:/root(7)# uname -a Linux moose 3.0.4-gentoo #1 SMP Fri Sep 2 17:49:29 CEST 2011 x86_64 Intel(R) Core(TM)2 Quad CPU Q9650 @ 3.00GHz GenuineIntel GNU/Linux root@moose:/root(8)# cp -a /mnt/v/RAID1/Workplace/uhligk/110710-Radtour/ ~rose/ root@moose:/root(9)# umount /mnt/v root@moose:/root(10)# diff -r ~rose/110710-Radtour/ ~rose/Txt/Pictures/Travelling/110710-Radtour/ Binary files /home/rose/110710-Radtour/Thumbs.db and /home/rose/Txt/Pictures/Travelling/110710-Radtour/Thumbs.db differ root@moose:/root(11)# ll /home/rose/110710-Radtour/Thumbs.db /home/rose/Txt/Pictures/Travelling/110710-Radtour/Thumbs.db -rw-rw---- 1 root nwaccess 117760 Aug 15 15:30 /home/rose/110710-Radtour/Thumbs.db -rw------- 1 rose users 65536 Aug 2 16:45 /home/rose/Txt/Pictures/Travelling/110710-Radtour/Thumbs.db Closing as we now have a amd64 stabled version greater than 3.0.4 which you reported as working. |
I tried to copy some files from a novell share to a local directory. I seems me that all files are copied, but nevertheless the copy command hangs and any other access to the novell shares are not possible: root@moose:/root(128)# cp -a /mnt/v/RAID1/Workplace/uhligk/110710-Radtour/ ~rose/Txt/Pictures/Travelling/ ^C^\^C^C^C^\^\^\^\^C root@moose:/root(20)# ps -ef | grep cp | grep -v grep root 16895 4729 0 Jul25 tty7 01:49:08 /usr/bin/X :0 -audit 0 -auth /var/gdm/:0.Xauth -nolisten tcp vt7 root 23498 3239 0 Aug02 pts/8 00:00:00 [cp] rose 30817 1 0 Jul26 ? 00:02:29 /usr/libexec/cpufreq-applet root@moose:/root(25)# ps -p 23498 ln F UID PID PPID PRI NI VSZ RSS WCHAN STAT TTY TIME COMMAND 4 0 23498 3239 20 0 0 0 11d120 S+ pts/8 0:00 [cp] root@moose:/root(26)# kill -9 23498 root@moose:/root(27)# ps -p 23498 ln F UID PID PPID PRI NI VSZ RSS WCHAN STAT TTY TIME COMMAND 4 0 23498 3239 20 0 0 0 11d120 S+ pts/8 0:00 [cp] So it is impossible to kill the copy command.
