free space seems wrong...

[Soeren Sonnenburg]

Hi.

I get

is_leaf: free space seems wrong: level=1, nr_items=7, free_space=3468 rdkey 
vs-5150: search_by_key: invalid format found in block 4792161. Fsck?
is_leaf: free space seems wrong: level=1, nr_items=7, free_space=3468 rdkey 
vs-5150: search_by_key: invalid format found in block 4792161. Fsck?

when accessing a certain directory using du and on the prompt
Input/output error.

 This does not happen when I iterate over the files by just using find /
...
 
The disk was full somewhen but now is only half full.

Should I be worried / is it necessary to fix the filesystem ?
The problem is, this filesystem is like 2-3 years old and was converted
to reiserfs 3.6 maybe a year ago...but as it is a production environment
I would not want to put it down at all...

Thanks for any help,
Soeren.

This is a sign of filesystem corruption,

This "free space" relates to in-tree nodes, not general filesystem situation.

Sure, you'd better run reiserfsck and follow it's advices.
Be sure to use latest reiserfsprogs.

You can run reiserfs --check even on readonly mounted fs just to get idea
on how broken it is and then to plan what to do next.

Bye,

Well... see below for the output of reiserfsck, which I just started on
the rw mounted fs (just to check whether the tool itself is the latest
version). The kernel now is 2.4.20 and it does correctly claim that the
fs is mounted on a different reiserfs partition (Partition /dev/sda6 is
mounted w/ write permissions, cannot check it)

I have no idea whether I should indeed do --rebuild-sb --rebuildtree ...

Do you want to run this program?[N/Yes] (note need to type Yes if you do):Yes
reiserfs_open_journal: journal parameters from super block does not match to
journal parameters from journal.

Either make journal partition available or use --no-journal-available
If you have the standard journal or if your partition is available
and you specified it correctly, you must run rebuild-sb.

There is a new check for journal parameters were added which helps to recover
fs with relocated journal and in a few other cases. These parameters were not
stored correctly in old kernels before relocated journal appeared. This is 
nothing to worry about, and you can fix if you run fsck --rebuild-sb and
say there to fix parameters in the jouranl by ones from the super block.

Ok. So I ran reiserfsck --rebuild-sb first and later with --check and
than --rebuild-tree... It connected very few files to lost+found and
finished within 1hr (its a ~3 year old 300G raid) - good job guys !

Thanks a lot,
Soeren.
