Probleme Copie/Synchro

[dudumomo]

Depuis quelques temps, je me retrouve confronter à un problème assez chiant.
Si je copie un fichier sur un support usb ca prend souvent pas mal de temps (Meme sur un disque dur externe). Et en plus, si j'enlève le support à chaud, les données sont souvent perdu... Je dois donc faire ejecter avant. Et ca prend beaucoup de temps encore une fois à finir la copie des fichiers (Parfois meme ca ne marche pas...)

Une idée ?

[Florimond]

pouvez répéter la question??? 

ils sont pas très chauds pour l'instants nos amis linuxiens, essayons le lancer le sujet...
en fait le problème en gros c'est que le transfert de données est excessivement lent quoi?

un petit tour dans les logs?

[koubi89]

peut etre au niveau au niveau du transfert (il ne prend plus en charge l'usb 2.0)

essaye de taper "lsmod" dans une fenetre de terminal et dit moi ce qui en ressort.

tape aussi lspci -v et donne moi les infos,on pourras surement regler ton soucis apres

[dudumomo]

Enfaite le transfert est hyper lent et ne se fait pas vraiment.
lsmod me donne :

Je dois refaire des tests. Et c'est quoi deja la commande pour voir le transfert du disque dur ? Je me souviens que dans Conky je pouvais voir le transfert en cours avant. Je dois re regarder.

Pourrais-tu me fournir ton fichier de configuration de compilation de noyau (/usr/src/linux/.config) s'il te plait ?

[dudumomo]

Merci de ton aide. Le voila en piece jointe.

[Elgrande71]

Il y a peut être quelques options de compilation qui pourraient posées problèmes.
Il faudrait désactiver dans l'USB le support OHCI, usb suspend, usb announce new devices pour commencer.

[dudumomo]

Ahhh c'est ptet pour ca !! Je vais y faire merci !

Alors, j'ai testé ainsi et ca a l'air bien mieux sur une autre clé USB. Mais toujours un comportement un peu bizarre. Les 300 premier mo se copie supervite comme si c'était un transfert sur un disque dur avec de bonne vitesse (Alors que la c'est une clé USB premier prix) apres ca copie plus lentement, mais ca copie. Puis une fois que c'est fini (Du moins, la barre de progression a atteint les 100% puis à disparu, je vois encore la led de la clé qui gratte pendant 20s. Puis apres elle s'arrete, j'ejecte la clé et ca se passe bien.

Bon c'est donc bien mieux ! Merci Elgrande.

je crois que la led des clef USB... faut pas trop s'y fier sous linux... moi sous Ubuntu elle est allumée en permanence, et c'est quand je démonte la clef dans le nautilus qu'elle se met à papilloter à toute allure!

[yarma]

en fait ton probleme n'est pas vraiment lié aux drivers, mais plutot au mode de transfert utilisé: tes transferts passent par la ram avant d'arriver à la clef => d'abord ca va super vite le temps de saturer le cache en ram, puis ca vide le cache dans la clef (c'est pour ca que ta clef clignote encore à la fin)....

pour éviter ca, il faut que tu ajoute "-o sync" quand tu monte ta clef ... tes données seront alors copiées de manière synchronisées, mais du coup ca ralentira un peu la vitesse du transfert (plus de contrôles)

[dudumomo]

Ah ! ca doit etre cela.
Parcontre, ca mount automatiquement. Et j'ai rien mis dans le fstab. Il va ptet falloir que je lui mette un point de montage et l'argument que tu m'as donné alors...

[yarma]

tu peux paramètrer des trucs pour le montage automatique soit en forcant des paramètres dans ton fstab, soit en passant par  hal, soit en utilisant l'utilitaire spécifique à ton environnement graphique (gnome-mount si tu es sous gnome)

[dudumomo]

Merci, je vais tester.
