No, nothing. At least in messages, kern.log and syslog.

But I found the problem. My old dir (on a reiser3 partition) was:
~/download/kde3/cvs which got renamed to old_cvs
My new reiser4 dir is
~/download/kde3/new_cvs

Since there are some full paths (maybe from make) I created a symlink
~/download/kde3/cvs

I removed that link and readded the one to the old partition, all make
processes stopped and I can access the partition again.
Note that I cannot reproduce this if I create just the symlink. That works
fine here, maybe I have to run make again to get the problem back.

Ok, after playing around with umount and kill I finally got some error 
messages. Don't know if they are important:

The mount hangs again. This time without a symbolic link.
umount -f /dev/hdb6 gives:

umount2: Device or resource busy
umount: /dev/hdb6: not mounted
umount: /home/hal/download/kde3/cvs: Illegal seek

Prozesses that use that partition:
# lsof | grep kde3/cvs
cc1plus   31258      hal  cwd    DIR       3,70       33    133147
/home/hal/download/kde3/cvs/kdelibs/kstyles/keramik

cc1plus   31258      hal  mem    REG       3,70    23725    135815

rm        31413      hal  cwd    DIR       3,70       33    133147
/home/hal/download/kde3/cvs/kdelibs/kstyles/keramik

I can't kill them, nothing in the logs again.

If there anything in /var/log/messages, or wherever your kernel log is
stored?

Reiser4 snapshot problems

[Felix Seeger]

Hi

I am trying out Reiser4 snapshot from August 26th.
I've putted my kde cvs sources on the new partition and compile from reiser4
now.

After some time processes hang when accessing this disk. I cannot do
anything on it but I also don't get any errormessage.

Umount, bash autocomletion and things like that don't work. Normal df and
mount are working btw.

Here are the line from strace when I call ls:

open("/lib/libattr.so.1", O_RDONLY)     = 3
read(3, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0\3\0\1\0\0\0`\r\0\000"..., 512)

Should I enable debugging to get some info ? What should I enable there ?

CONFIG_REISER4_FS=y

CONFIG_REISER4_LARGE_KEY=y
# CONFIG_REISER4_CHECK is not set
CONFIG_REISER4_USE_EFLUSH=y
# CONFIG_REISER4_BADBLOCKS is not set

thanks
