Mount options NOATIME and NODIRATIME
But I don't see those on the current Reiser doc pages.

In a earlier life I had implemented Reiserfs for a series
large (200Gb
) samba filesystems. We experienced significant problems at the peak
access times (9am and 4pm) after many months of hair pulling we found
the culprit. The last referenced field was being updated and locked,
with the lock being held much longer than expected.
There is an option to turn off updating the last referenced
field but I
can't find my notes from 3 years ago.. When this was resolved we
acheived up to very reasonable response time with hundreds of
concurrent
users.
Now to find that setting....

Just trying to gauge which is the more popular filesystem
type to use
for
logical volumes, reiserfs or ext3 and why.
Reiserfs is more popular, because it is the default in SuSE. We've
observed a fair number of cases where reiserfs fails at very high I/O
rates, so we tend to use ext3 in places where we know it's
going to get
beaten hard. reiserfs performs slightly better than ext3 on
filesystems
that will have a lot of small files (that's its design point
anyway) so
you may need to mix and match.
Seems like reiserfs will allow resizing through the YaST GUI, whilst
ext3
filesystems forces CLI interaction.
Install EVMS and use evmsn in place of the YaST storage gui. Then you
get a nice front end for both, and a whole lot more.

Well to 200gb isn't small, and each samba server was managing multiple
200gb filesystems. So we all define lg and sm differently.
