Re: [Sheflug] ReiserFS vs. Ext3fs ... :-)

[James Wallbank <xxxxx [at] xxxxxxxxxxx>]

Hi All,

Sorry to join this thread late - but I thought it was interesting and 
I have a question.

(1) We've installed Reiser on several P166's at Access Space and they 
seem to work fine - then again, user data is stored on an NIS server, 
so maybe Reiser doesn't have too much journalling to do. With 
individual users only and remote data storage there doesn't seem to 
be a perceptible speed difference. It'd probably be a different 
matter on a server.

(2) I've just installed ext3 on two new Mandrake 8.1 rc1 boxes 
(again, P166's). I'll tell you how they get on.

(3) How do you get ext3 to fall back to ext2? In the interests of 
science I'll make one of the P166's fall back to ext2 and see if I 
can spot the effects.

(4) The only reason I can see for favouring ext3 over Reiser is that 
you can't hack Reiser partitions with my trusty TOMSRTBT maintenance 
disk - they just show up as "type: unknown". I'm pretty confident 
that TOMSRTBT will recognises ext3 as ext2 but at least I could use 
it to dub off files if an h/d becomes deeply mangled.

Cheers,

James
