Reprise du message précédent
Bonsoir,mrk.n :
c'est un peu ce que j'ai ditJe me pose la question pour la partition étendue parce qu'elle n'est en fait qu'un "conteneur" et c'est aux partitions qui sont à "l'intérieur" qu'il faut en fait accéder.
kalagani :
que je complèterai en précisant que l'étendue n'est le conteneur dans son EBR que de 2 adresses de partitions:en fait l'étendue ne sert que de relais pour accéder à la 1ère logique qui elle doit être alignée puisqu'elle contient des données, alors que l'étendue n'a que le 1er secteur EBR qui sert, le reste (2030-1 ou 2048-1) étant perdu...
_celle sur la 1ère partition logique
_celle de chainage sur le prochain EBR (s'il existe)
lequel second EBR contiendra lui aussi la même chose et ainsi de suite...jusqu'au max de 20 partitions logiques je crois!
Là que l'étendue ne soit pas alignée n'est pas gênante en terme de taille de donnée utiles à accéder, (l'EBR et ses 512 octets)
ce qui pourrait être pénalisant est le nombre d'accès, mais vu le peu de donnée à lire il est peu probable qu'il y ait 2 accès pour cela...L'important c'est que les partitions logiques soient elles alignées!
Citation :
C'est l'éternel problème entre ce qui est utile pour l'un ou pour l'autre.Je ne pense pas que la colonne "O" soit la plus importante ou alors il faudrait afficher un nombre impressionnant de décimales, c'est la raison pour laquelle j'ai choisi volontairement de ne mettre aucune décimale en sachant que ce n'est pas sur cette colonne qu'il faut se baser, elle n'est qu'un ordre de grandeur.
Perso, 3 colonnes me suffiraient avec la "O" dont le résultat ne doit pas tolérer d'arrondi dans le calcul
puisque je persiste c'est elle qui détermine le début de la partition, s'il y a une virgule c'est que la partition n'est pas alignée.
Une seconde pour le calcul de la taille...La 3ème un modulo 2048 sur la fin partition pour être au plus près de 2047 histoire d'avoir le dernier accès le plus "plein" possible, sachant qu'il ne le sera jamais puisque la fin d'une partition ne peut être alignée sauf à perdre 1 secteur entre fin alignée et début alignée de la suivante...
Citation :
un OS doncsda5 Mga3 29 Gio
puisque pas d'autre partition logique derrière, l'EBR de cet OS n'a pas de chainage
alors je tenterai (je ne l'ai jamais fait) une sauvegarde via dd
dd if=/dev/sda5 of=/point de montage d'un des DD/saveMageia3.img bs=4k
destruction de /dev/sda5 et /dev/sda4
reconstruction des 2 en alignant avec fdisk
restitution en se mettant sur le DD où est l'image
dd if=saveMageia3.img of=/dev/sda5 bs=4k
Note: faut être patient avec dd, c'est long de chez long...
EDIT 29/04/2014: pour la sauvegarde de cette sda5 il te faut aussi la place sur le DD qui doit la recevoir...
Mais avant de risquer la manip compare tes partition en lecture/écriture avec les commandes dd que j'ai mises plus haut
Comparaison de ton SSD
Citation :
avec 1 de mes DDCode BASH :
Timing cached reads: 1626 MB in 2.00 seconds = 813.48 MB/sec Timing buffered disk reads: 634 MB in 3.00 seconds = 211.03 MB/sec
Code BASH :
accès direct meilleur sur le SSD mais étrange pas quand le cache est en jeu!!!Timing cached reads: 2084 MB in 2.00 seconds = 1041.59 MB/sec Timing buffered disk reads: 400 MB in 3.01 seconds = 132.91 MB/sec
Même chose pour les RA SSZ BSZ, ton SSD
Citation :
mon même DDCode BASH :
blockdev --report /dev/sda? RO RA SSZ BSZ 1er sect. Taille Périphérique rw 256 512 4096 2048 31457280000 /dev/sda1 rw 256 512 4096 61442048 31457280000 /dev/sda2 rw 256 512 4096 122882048 31457280000 /dev/sda3 rw 256 512 1024 184324077 1024 /dev/sda4 rw 256 512 4096 184324096 31457280000 /dev/sda5
Code BASH :
_RA (Read-Ahead) buffer en avance de phase pour améliorer la vitesse de lecture si j'ai bien comprisblockdev --report /dev/sdb? RO RA SSZ BSZ 1er sect.

identique à la valeur par défaut de 256 secteurs
_SSZ size bloc logique identique aussi...en octets
c'est sur ces 2 paramètres que je pensais trouver une différence
_BSZ c'est la taille en octets du bloc du système de fichier utilisé sur la partition
4kio pour NTFS, ext4; 512 pour FAT chez moi
à noter le cas particulier de l'étendue dont le bloc et la taille ne font que 1024 octets/secteurs...

nmrk.n :
Tu te compliques la vie, pour moi le but est d'aider à partitionner via une feuille de calcul qui:C et 2048 étant toujours des entiers positifs, P est toujours un entier positif; il n'y a donc pas lieu d'afficher les décimales.
Tu n'as rien dit à ce propos, tu n'es pas d'accord ?
Tu n'as rien dit à ce propos, tu n'es pas d'accord ?
_à partir des données début et fin, étendue ou pas, de chaque partition que tu renseignes à gauche dans ta partie verte
_te calcule partie droite:
une colonne : début/2048=entier=aligné=>pas d'arrondi dans la formule
une colonne : (fin-début)*512=taille en octets de la partition
une colonne facultative : fin+1(modulo/2048)=fin aussi alignée mais pas important
sachant que le calcul doit prendre en compte le champ Extended pour ajouter 2048 à tous les débuts de partition logique comme le font parted et fdisk
Après tu peux agrémenter avec d'autres colonnes comme tu veux.
Bon, j'en reste là sur ton fichier, car on diverge ce n'est pas le sujet du Topic :+)
nmrk.n :
et des DD...Ma machine ne me permet pas d'activer l'AHCI ce qui serait préférable voire important pour un maximum de performances du SSD.
nmrk.n :
Actuellement, j'ai un PC de transit à P4/3Ghz aussi, 4Gio de RAM avec OS double boot XP/Cauldron4Mon processeur est Pentium IV 3 Ghz monocœur (2 cœurs virtuels) avec 2 Gio de RAM.
La CM est une ASUS P5B, son BIOS permet l'AHCI que je n'ai pas tenté car j'ai un doute:
son chipset est ICH8 et j'ai cru lire qu'il fallait un ICH8-R
Quand bien même, il me manque aussi les pilotes AHCI pour XP...les autres OS Microsoft n'ont pas ce pb.
Pour revenir au Topic, as tu comparé tes partitions avec dd?
Car si ta sda5 logique te donne les même résultats que tes primaires, pas la peine de réaligner l'étendue à mon avis.
(Sinon j'ai oublié mais pour la sauvegarde de cette sda5 il te faut aussi la place sur le DD qui doit la recevoir...)

Bonjour,
Désolé mais je ne vois pas ce que je dois faire ?

Désolé mais je ne vois pas ce que je dois faire ?
je veux dire de reprendre les bouts de commande (mis plus haut) avec dd et hdparm pour les appliquer à chacune de tes partitions.
Si pas de différence flagrante entre tes partitions primaires alignées et ta partition logique elle aussi alignée mais passant par le chainage de l'Etendue non alignée, alors pas besoin de t'ennuyer et de prendre des risques à réaligner cette Etendue!

Comment détermines tu le nombre de plateaux d'un DD? (hdparm -I ne me semble pas le donner)
Je ne sais pas. Peut être le site du constructeur ?
Ce genre d'info se trouve aussi dans les tests de DD réalisés sur hardware.fr. Y a plus qu'à retrouver le test du tien

plus besoin de mettre le I dans la commande, car la seule partie intéressante pour ce test en lecture se retrouve en fin de la même info répétée, -tT suffisent!
Ensuite, il ne faut comparer entre elles que les partitions du même type, ainsi tu peux exclure le résultat de sda1 car c'est du NTFS et de sda4 l'Etendue pour ne comparer que sda2, sda3 et sda5 qui sont du même type ext4.
Et avec dd sur différentes tailles de bs notamment en écriture?

Horreur, personne ne me comprend :+)À vrai dire je ne comprends pas à quoi ça sert ?
Et bien, j'écrivais dans le 1er post de ce Topic
Citation :
lequel je concluais pardevant faire un nouveau partitionnement sur un DD, je me pose la question de savoir quel est le meilleur alignement pour éviter des
pertes de performance quand le buffer de données à accéder est en frontière de cylindre/secteur, lequel impliquerait 2 accès DD au lieu d'1 si ce buffer de données n'avait pas été en frontière...

Citation :
Alors, je ne sais pas si j'ai tout compris, mais ce dont je suis sûr c'est qu'il me fallait le moyen de vérifier qu'un alignement pouvait influer sur les performances.Alors ai je bien compris?
bien aligné?
Quel est le moyen de vérifier?
bien aligné?
Quel est le moyen de vérifier?
Donc trouver un moyen de lire et d'écrire sur le DD pour connaitre les débits respectifs
et ensuite "jouer" sur l'alignement de ce même DD et comparer les dits débits entre eux, ceci avec le même moyen de lecture/écriture.
Après force navigations, je me suis rabattu sur hdparm et dd en lecture et le seul dd en écriture conforté en cela par le lien fourni par MadTux
Au passage, ce moyen de lecture/écriture permettrait aussi de mettre en évidence
l'influence de la taille du blocsize du système de fichier employé
l'influence de la position physique de la partition par rapport au centre sur un DD (pas sur un SSD)
Et pour en venir à ton cas de SSD
il s'agit de comparer les débits de lecture et d'écriture entre tes 2 partitions primaires ext4 alignées et ta partition logique ext4 alignée mais dont l'accès se fait par le chainage de la partition étendue non alignée.
Si la moyenne de plusieurs séquences de lecture et d'écriture ne montrent pas d'écart significatif, il n'y aurait pas besoin de réaligner l'étendue...
Dans le détail, en ne s'intéressant qu'au Timing buffered disk reads de hdparm, pas de différence flagrante,
par contre pour dd, l'esprit malin s'est aussi joué de toi
Citation :
...donc à refaireEn effet je croyais faire des lectures directes via dd, mais il semble qu'un esprit malin se joue de la mesure d'où cet épice qui vide le(s) cache(s)...
blockdev --flushbufs
blockdev --flushbufs
Citation :
Je peux écrire sans risque sur mes disques ?
OUI, si tu ré-écris sur des fichiers existants, NON si tu crées de nouveaux fichiers pour le test comme montré dans mes exemples...tmpFile
Perso, je met au point un script qui fait tout cela en automatique, et pour sa mise au point je l'ai fait tourner sur les DD de 3 PCs
2 en double-boot, 1 en quadruple-boot, soit un total de 5 DD et pour l'instant je n'ai rien écrasé...vite un bout de bois...

Je l'ai testé sous chaque Linux embarqué de 3 PC différents et sur les 5 DD de ceux-ci
_2 PC double-boot XP/Linux (Cauldron4 et Mageia2) à 2 DD chacun
_1 PC quadruple-boot XP/Seven/Mageia4/Kubuntu LTS 12.04 à 1 DD
et aussi à partir d'un clé USB Live Fedora18, solution la plus neutre pour tester je pense, vu que le DD en test est "idle" car aucun OS ne tourne dessus dans ce cas et que le script de test tourne lui à partir d'une autre clé USB.
...et miracle autant les DD que les PC ont survécu :+)
Ce script se lance en root et commence par demander quel DD (ou SSD) il faut tester
Code BASH :
_puis exécute sur chaque partition, exceptées l'Etendue et la Swap,bash testDD.bash

avec au besoin, création point de montage et montage des partitions pour les fichiers tmp d'écriture, lesquels, montage ou non, sont effacés en fin de boucle,

Par curiosité j'ai comparé les résultats de cette méthode avec les 2 autres pas "PROPRES" à savoir ceux obtenus sous Mageai4 et Kubuntu 12.3 LTS...
Et bien surprenants, autant je me doutais qu'il fallait exclure les partitions / et /home de la comparaison , autant je ne pensais pas trouver une telle dispersion notamment en écriture sur les partitions ntfs pourtant à priori exclues du côté "juge et partie"! Pour ne pas déjà me dire que j'ai accouché d'une souris avec ce script, je dirais dans un premier temps que seule la méthode "NEUTRE" est à utiliser!
En attendant de l'utiliser sur le nouvel alignement, j'ai avant d'effectuer celui-ci sauvegardé, via dd, toutes les partitions sauf la swap et la dernière, de façon à les restituer ensuite, n'ayant pas envie de réinstaller les 4 OS.

tout comme il l'aurait été entre les débuts de l'étendue et de la première logique, ici 64, mais il aurait été possible de mettre 2 seulement...
Pour info, résultats "juge et partie" dans le post suivant, car impossible à ajouter dans celui-ci, il semblerait qu'il y ait une limite...

J'ai restitué les partitions toujours avec dd et retrouvé au mieux seulement 3 OS opérationnels, les 2 Linux et XP,En attendant de l'utiliser sur le nouvel alignement, j'ai avant d'effectuer celui-ci sauvegardé, via dd, toutes les partitions sauf la swap et la dernière, de façon à les restituer ensuite, n'ayant pas envie de réinstaller les 4 OS.
toutes mes tentatives pour rendre aussi Seven opérationnel ont échoué, au mieux je retrouve son multi-boot mais alors perds XP.
Si j'ai le courage je mettrais ici pour info les quelques pièges/résolutions qui m'ont permis d'arriver à cet état...Bref, j'ai fait tourner le script sur le PC avec juste les 2 Linux utilisables.
1er piège: restitution sur une partition plus petite
dans mon réalignement, toutes les partitions se sont vues augmentées en nombre de secteurs, sauf sciamment les /home des 2 Linux, d'où message dd car pas assez d'espace
Caché :
Le fait de tronquer la restitution au nombre de secteurs de la nouvelle partition fait bien disparaitre l'erreurCode BASH :
dd of=/dev/sda9 if=/run/media/liveuser/QUADRA2_N/sda9.img conv=noerror bs=4k dd: writing ‘/dev/sda9’: No space left on device 2622464+0 records in ->10741612544 2622463+0 records out->10741608448/512=20979704secteurs 10741612032 bytes (11 GB) copied, 654.793 s, 16.4 MB/s
Caché :
car il y a maintenant adéquation entre taille de la recopie et taille de la partitionCode BASH :
dd of=/dev/sda9 conv=noerror bs=4k if=/run/media/patrick/QUADRA2_N/sda9-2622463.img 2622463+0 enregistrements lus 2622463+0 enregistrements écrits 10741608448 octets (11 GB) copiés, 315,184 s, 34,1 MB/s
Mais le Linux (Kubuntu, ici) ne démarre pas à cause du check qu'il fait signalant que le superbloc ne correspond pas à la taille physique
Confirmé par un check en live avec ma clé Fedora
Caché :
Il faut donc appliquer un second remède, un resize car la source même tronquée à la recopie embarque la taille d'origine dans son superblocCode BASH :
fsck.ext4 /dev/sda9 e2fsck 1.42.9 (28-Dec-2013) La taille du système de fichiers (selon le superbloc) est de 2622611 blocs La taille physique du périphérique est de 2622463 blocs Le superbloc ou la table des partitions est peut-être corrompue ! Arrêter<o>?n /dev/sda9 contient un système de fichiers comportant des erreurs, vérification forcée. Passe 1 : vérification des i-noeuds, des blocs et des tailles Passe 2 : vérification de la structure des répertoires Passe 3 : vérification de la connectivité des répertoires Passe 4 : vérification des compteurs de référence Passe 5 : vérification de l'information du sommaire de groupe /dev/sda9 : 225/655776 fichiers (1.3% non contigüs), 85804/2622611 blocs
Caché :
Code BASH :
et maintenant le check est OKresize2fs /dev/sda9 resize2fs 1.42.9 (28-Dec-2013) En train de redimensionner le système de fichiers sur /dev/sda9 à 2622463 (4k) blocs. Le système de fichiers /dev/sda9 a maintenant une taille de 2622463 blocs.
Code BASH :
fsck.ext4 /dev/sda9 e2fsck 1.42.9 (28-Dec-2013) /dev/sda9 : propre, 225/655776 fichiers, 85804/2622463 blocs
2ème piège: ne pas avoir sauvegardé la swap
et oui, la swap commune aux 2 Linux, en sda1, exempte de données ne m'a pas semblé nécessaire à sauvegarder,
mais quand son tour en dernier est arrivé de la déplacer de 1 à 64, aucun Linux ne démarrait, blocage sur un écran noir avec écrit GRUB en haut à gauche!!!
Et même la tentative de réparation avec le DVD Mageia4 échoue indiquant un pb de swap!
Il m'a fallu repasser en Live Fedora pour formatter la partition
Caché :
Hélas encore même blocage sur GRUB mais cette fois la réparation avec le DVD Mageia4 va jusqu'au bout,Code BASH :
Cette fois parted voit bien le type swap alors qu'il ne le voyait pas avantmkswap -c /dev/sda1 Setting up swapspace version 1, size = 8402908 KiB no label, UUID=56e341e6-a10e-4a70-8d2d-fecc039d37d6
Code BASH :
1 32.8kB 8605MB 8605MB primary linux-swap(v1)
Re-hélas Mageia4 ne boote pas: message d'UUID pas trouvé
Caché :
et oui le formattage a donné un nouvel identifiant UUID ce qui amène au blocage de Mageia4Code BASH :
dracut Warning: Could not boot dracut Warning: /dev/disk/by-uuid/7b3d424d-38ab-4709-ac5e-541f62ea6e1a does not found
...mais pas de Kubuntu alors que son fstab référence l'ancien UUID

Bon, le remède ré-allouer l'ancien UUID à la swap en la formattant de nouveauCode BASH :
# swap was on /dev/sda1 during installation UUID=7b3d424d-38ab-4709-ac5e-541f62ea6e1a none swap sw 0 0

Re-re-hélas, Mageia4 ne démarre toujours pas même si le message d'erreur ne fait plus apparaitre l'UUID de la swapCode BASH :
ouf sda1 a retrouvé son ancien labelswapoff /dev/sda1 mkswap -c -U 7b3d424d-38ab-4709-ac5e-541f62ea6e1a /dev/sda1 mkswap: /dev/sda1: warning: wiping old swap signature. Setting up swapspace version 1, size = 8402908 KiB no label, UUID=7b3d424d-38ab-4709-ac5e-541f62ea6e1a

=> remise de l'ancien UUID dans le fichier menu.lst et enfin Mageia4 démarre
Comme quoi si j'avais bêtement sauvegardé puis restitué la swap, je ne serais pas tombé dans cette succession d'hélas :+)
3ème piège que je n'ai su résoudre...Seven ne démarre plus
A ce stade les 2 Linux sont enfi fonctionnels sur les partitions déplacées...
Mais pas les Windows, sauf XP qui a fini par démarrer en faisant /fixboot dans le menu de récupération de son DVD d'installation lequel a sans doute dégradé le bootloader de Seven.
Rien n'y a fait, formattage des partitions ntfs sous Linux sous Windows, j'ai même de nouveau bloqué Mageia4 car l'UUID de XP avait changé, il m'a fallu une nouvelle fois restitué XP avec sa sauvegarde. Kubuntu dans ce cas a été plus tolérant dans la mesure où il ne restait pas bloqué mais proposait de passer outre à l'erreur de montage de cette partition XP (un simple s à taper au démarrage)...
Au mieux j'ai retrouvé le multi-boot Microsoft mais alors ni XP ni Seven ne se lance...
Et là même si je suis curieux, j'ai abandonné...le sujet étant Performance partition...

... à partir d'un clé USB Live Fedora18, solution la plus neutre pour tester je pense, vu que le DD en test est "idle" car aucun OS ne tourne dessus dans ce cas et que le script de test tourne lui à partir d'une autre clé USB.

Et bien en écriture, le résultat est meilleur, (jusqu'à ~3MB pour les bs > 512) sur les 3 premières partitions , celles en début de DD, puis cette amélioration n'existe plus, cf synthèse des moyennes:

_aligné sur cylindre commençant au secteur 1 puis absolument pas sur un multiple de 1Mio (2048 secteurs)
_aligné sur multiple de 32Kio ET en même temps de 1Mio (64 ET 2048 secteurs),
sauf début (sda1) commençant au secteur 64 et étendue (sda4) uniquement multiple de 32Kio
...et bien uniquement gain en écriture en début de DD...
