Hi,

I have several r4 partitions, all with cryptcompress.

I tried 2.6.38.x6 a few hours ago - after 3h I looked at dmesg and
it
was
swamped with error messages and tracebacks. Sadly I tried to run
fsck
before saving dmesg - and the box froze completely.

I am now back to 2.6.36.4. fsck is running on one of the partitions.
Meanwhile I see tons of this:

[  153.379751] reiser4[kuiserver(2649)]: reiser4_inflate_cluster
(fs/reiser4/plugin/file/cryptcompress.c:1136)[edward-1460]:
[  153.379756] WARNING: Inode 2975012: disk cluster 27 looks
corrupted
[  163.301372] reiser4[kuiserver(2669)]: dc_check_checksum
(fs/reiser4/plugin/file/cryptcompress.c:969)[edward-156]:
[  163.301374] WARNING: Bad disk cluster checksum 799645291, (should

546616041) Fsck?-2)

[...]

known problem with 2.6.38.X?

Yes, this is known and old problem.
This is not specific to compression.

ok, and how serious?

Serious for what?
Reiser4 in the current state is not suitable
for production file servers. For home desktop -
may be..


   I am going to let fsck loose as soon as the first

partition is done. Should I prepare for some major cf?

I _can_ reproduce this problem.
I don't need any extra-stuff.

and I don't expect you to.

well, fsck worked.

The partition was md1 - which means /var, which also houses portage tree on my
setup and some other vital stuff.

The first run with --build-fs failed with an 'unknown plugin id' error
finishing with an 'operational error'.


This looks like bug in fsck.
Not related to the crash you have reported though..


Secound run with --build-fs was successfull with only some files in
lost+found. The important stuff seems to be there.

R4 worked for me fine for a long time. But it seems like I should migrate the
more important partitions away from it.

I'll report as soon as I find the problem.

Thanks,
Edward.
