Hello!
I just hit a problem with reiserfs. While working this popped on the console:
ReiserFS: sdb2: warning: vs-13060: reiserfs_update_sd: stat data of object [2497 4756 0x0 SD] (nlink == 2) not found (pos 1)
ReiserFS: sdb2: warning: zam-7002:reiserfs_add_entry: "reiserfs_find_entry" has returned unexpected value (3)
REISERFS: panic (device sdb2): vs-7050: new entry is found, new inode == 0
And then suddenly some services (webmail, courier-imap) stopped working properly,
as if they hung upon read/write on /dev/sdb2 (which is /home that contains mail)
I noticed that load was increasing continuously, 5,7,9,12,...,60.
I tried remounting in read only to do a reiserfsck but
mount -o remount,ro /dev/sdb2 only hung and it was not possible to stop it.
Unfortunatelly I discovered it being remotely logged on, and I can't log in
now to further investigate. But I managed to look at syslog and copy the
oops call trace that was just after the 3 messages I wrote above.
This is vanilla 2.6.15, /dev/sdb2 is a reiserfs on a 0+1 RAID ran by aacraid.
No 3rd party modules.
Currently I can not supply any more information due to the server not
letting me in, ie. hanging just after displaying Last login info.
Just letting you guys know. I hope the fs is intact :-)
Best regards,
Maciej Soltysiak

rename encountered "hidden" name when it should not be there.
the attached patch should make reiserfs to not panic but return -EIO.
It would be interesting to know how did you manage to create hidden
names.

Ok, I'll apply that patch and be on the lookout for this warning.

Well on this partition hidden names could have been created either by:
a) bash, and mc with files like .bash_history, etc.. (all standard stuff)
b) courier-imap which creates directories for IMAP folders, like:
.My Folder
.Sent
.Trash
For now, I have no clues about it.

Sure thing.
Thanks a lot.
