Hello,
I'm using a reiser4 FS for compiling my linux kernel.
Today, the kernel panics while compiling. I guess it was
a reiser4 panic. I can't be sure as I was using an X console,
but I'm often hit by such reiser4 panics (see my others posts
on this list).
So I reboot using the reset button and I restart the
compilation. I then had weird compilation errors until
I unmount this FS and fsck it. Here is the fsck output:
[EMAIL PROTECTED] ~]# fsck.reiser4 --fix /dev/vglinux1/lvkernel
*******************************************************************
This is an EXPERIMENTAL version of fsck.reiser4. Read README first.

Fscking the /dev/vglinux1/lvkernel block device.
Will fix minor corruptions of the Reiser4 SuperBlock.
Will fix minor corruptions of the Reiser4 FileSystem.
Continue?
(Yes/No): yes

Closing fs...done
FS is consistent.
After this, I was able to compile again.
Note that I found the following message in dmesg (before fsck):
Aug 7 17:50:19 antares kernel: reiser4[make(3875)]: present_lw_sd
(fs/reiser4/plugin/item/static_stat.c:276)[]:
Aug 7 17:50:19 antares kernel: WARNING: is encountered
It woud be nice if reiser4 could print the name of these
"partially converted files".
But my main concern is that i was thinking that using a *journalized*
file system will make useless the fsck after crash. Am I wrong here ?
