I get these errors since weeks when posting, usually this is caused by a
broken windows mta which replies to the wrong address (me instead of the
mailing-list manager). since postfix does not do that, is this particular
postfix installation just plain broken or is the reiserfs mailinglist
doing funny things (namely just forwarding mails)?
In any case, PLEASE unsubscribe this annoying @cjkcode.com address form the
mailinglist (and let's hope this is not a forward).

Subject: [reiserfs-list] reiserfs unusably slow when >90% full?
From: <[EMAIL PROTECTED] ( Marc) (A.) (Lehmann )>
Date: Wed, 29 Aug 2001 20:47:56 +0200
To: [EMAIL PROTECTED]
I wondered why my raid systems became so slow recently and found the
reason: when a reiserfs filesystems gets 90% full it starts to become
VERY slow on writes. My filesystems usually do in excess of 20MB/s when
writing, but this degrades to about 10mb/s at 95% and goes down to 1mb/s
at 98%. When deleting files again the filesystem becomes faster again.
Now, the rule is that you need about 5% of free space on an ext2 disk to
keep it defragmented, but in practise you need one GB or so and everything
will always be fine. Degradation never becomes more than a few percent
even on totally full ext2 partitions.
I think I remember that reiserfs needs 90% of free space (and this indeed
is backed up by the speed I see), but this means 20-40GB of free, unused
space on these disks (which seems a bit excessive).
I am using linux-2.4.8ac9 currently, and it may be possible that other
kernels didn't show this behaviour (I didn't use the ac series before). In
any case, is this a bug and is there a fix available?
Thanks a lot for any info ;)
