FTP transfert causes 100% use of rootvg



hello

i made an Oracle Dump.

When i get my dump ( 7 Go ) with ftp, the server is like hang.
I can not send any command with my terminal.

the transfert is short ( less than f5 minutes ), is complete. And
after all is ok.

the server responde good.

During the transfert, i have see with topas that the rootvg's disk is
100 % busy.
I understand why the server seems hang when the rootvg's disk is 100 %
busy.

but i don't understand why the transfert cause 100% !!

the server :
Aix 5.3 with VIO server
10 Go of RAM
10 go of swap on rootvg.
the disks are on a SAN
the network is 1000 mo

if you have any idea

Thanks

Pour les francophones :
lors que je récupere un dump oracle de 7 go via FTP, le serveur parait
bloqué. Je ne peux plus taper une seule commande dans une fenetre
determinal.
Le transfert se finit correctement, est tres rapide.
Ensuite je récupere la main correctement sur le serveur

Avec un topas, j'ai vu que le disque sur lequel se trouve le rootvg
est utilisé à 100%. Ce qui explique pourquoi les commandes ne passent
pas bien du tout

C'est la premiere fois ou je vois qu'un transfert FTP bloque une
machine.
c'est un Aix 5.3 virtuel , avec un VIO serveur, 10go de ram, 10 go de
swap, un reseau au giga. Les disques sont sur un SAN plutot
performant.

Serait-ce le réseau qui est trop rapide ?

si vous avez des idées
Merci à vous

Fabien
