fatal "not directory found" error at pass 3a of reiserfsck

fatal "not directory found" error at pass 3a of reiserfsck

[Alain Knaff]

We have a corrupted reiserfs filesystem here which can't even be repaired with 
--rebuid-tree.

The error messages happens at pass 3a:


Pass 3a (looking for lost dir/files):
####### Pass 3a (lost+found pass) #########
Looking for lost directories:
lost+found.c 116 _look_for_lost
not directory found
Aborted


What can we do to retrieve our files?

Thanks,

Alain

this seems to be fixed already.
sending the fixed reiserfsprogs version in the next email.

Actually, the problem happened with reiserfs-3.6.18-5 (as shipped by 
SuSE 9.3. and 10.0.).

Later, I downloaded 3.6.19 from namesys, and that one already 
successfully restored the disk (but due to size and slowness of our 
hardware this took several hours and terminated just now a quarter of an 
hour ago).

Now, we'll first do a backup (yeah, we learned that lesson!), and after 
that I'll re-run your 3.6.20 and report back (will probably take until 
next morning, though)

Thanks,

Alain

if rebuilding the tree has been finished, you do not need to rebuild 
it again, you can merely double check the fs consistency with --check
(default) option.

Even though 3.6.19 apparently "succeeded" with its rebuild-tree, 3.6.20 with 
--check still found errors, so we had to run this with rebuild-tree as well.

But that run finished all right, and succeeded in retrieving one additional 
file, which 3.6.19 hadn't.

Many thanks,

Alain
