considerations for reiserfs with lots of files.

["Pysiak Satriani" <pysiak.satriani@wp.pl>]

Hi!

I am running a mail server that stores email on a 270G reiserfs 
partition in a Maildir format (one file per email message)

I have an account that is a kind of a tap and receives tremendous 
amounts of email. In just over 2 months I have 233k email 
messages, ie. 233k files in one directory!

Now, the obvious thing is that accessing that directory takes 
some time, I understand that, but I am having other problems with 
it. Since creating that account I started having strange problems 
like:
- files impossible to delete/read/rename (well actually I found 
one like that)
- reiserfsck --fix-fixable told me that it found some nodes that 
need --rebuild-tree
- I had an reiserfs related oops, unfortunately It did not save 
to the log.

So my question is, are there any special considerations for 
reiserfs with huge directories?

I am running 2.6.16.11, the partition is mounted exec,dev,suid,
rw,noatime,notail,iocharset=iso8859-2

It is qmail and courier-imap that operate on these maildir 
accounts.

Best regards,
Maciej
