I was using Reiserfs on some machines at my last job; I left before they 
had a chance to go into production but it seemed to work well.  One 
caveat to bear in mind is that the journal portion of Reiserfs, at least 
as of a few months ago, did not have its format fully stabilized yet. 
Upshot of that is that future versions of Reiserfs may need you to back 
up your data before an upgrade, reformat and restore afterward in order 
to be compatible with any changes that they make to the journal format. 
  Not pretty with large volumes.  But it seems to work for now.

Didn't do any of my own speed trials, didn't have to live with it for 
very long, didn't try it on anything crazy like software RAID volumes (I 
understand that's still a no-no regardless of whose journaling fs you 
use), but I can say for certain that it can recover from a power outage. 
  First thing we did on our test boxes was yank the power a few times, 
and sure enough, the reiserfs portions of the filesystem came back on in 
nothing flat.

If you want to toy with this, you might want to buy or download a copy 
of S.u.S.E., they have resierfs as an option for all but the root 
partition, and strapping on a root with reiserfs shouldn't be _too_ hard.

rpmfind.net has been using ext3 for several months now, and they seem to 
like it; I haven't tried it yet myself but given the amount of traffic 
that site sees, it must be at least decent.

HTH,
