Démarrage sur DD en SSD pas très rapide

Salut à toutes et tous,
Depuis 1 an maintenant mon ordi est sous Ubuntu, après des test divers de Studio, Debian, Lubuntu etc... je me suis fixé sur la version Ubuntu "normale" donc la 14.10 puis la 16.04.
Mais je viens tout juste de tilter que mon ordi met à peut près 2 minutes pour s'allumer et être opérationnel alors que tout est installé sur un DD en SSD...
Est-ce que quelqu'un aurait des pistes de recherche sur la provenance de ce ralentissement? le SSD est assez vieux désormais, est-ce que cela pourrait avoir une incidence?
Merci d'avance si vous avez des idées.
(bon sachant que je tripatouille l'informatique mais n'ai pas une grande connaissance)
A+

Re : Démarrage sur DD en SSD pas très rapide

Bonjour,
Depuis une session de ton Ubuntu installé, je te prie de faire un Boot-Info et de donner l'URL de ce Boot-Info dans ta réponse.

EDIT : tu as noté dans le post #1 "donc la 14.10 puis la 16.10". La version 16.10 n'est pas encore sortie officiellement (voir ici). Je te prie de confirmer ou pas qu'il s'agit bien de la 16.10. Si c'est une erreur, je te prie de modifier ton post #1 pour remplacer "16.10" par le bon numéro de la version.

Re : Démarrage sur DD en SSD pas très rapide

Bonjour Malbo,
bon je suis complètement à la masse...
Mon DD n'est absolument pas un SSD (je viens d'ouvrir ma tour pour regarder), donc sur cet aspect je passe mon tour et ce sujet de forum n'a plus lieu d'être.
Par contre à la lecture du boot-info (ici: http://paste2.org/Wstbs1bM) je me rend compte que mon DD de 750 Go qui contient ubuntu est nommé sdb alors que mon DD de 1To qui me sert juste de stockage de données est en sda. Est-ce que cet ordre des disque dur a une importance?
Dernière chose, toujours sur le boot info, je remarque qu'il reste des traces de Windows vista ce qui me rend perplexe, d'une car je pensais avoir fais le ménage et de deux car je n'ai jamais eu vista...

Bon désolé pour mettre planté dans mon matériel!!!

Merci en tout cas d'avoir pris du temps pour me répondre.
A+
Tchaeroo

=================== Suggested repair
The default repair of the Boot-Repair utility would purge (in order to enable-raid enable-lvm) and reinstall the grub2 of mapper/ubuntu--vg-root into the MBR of sda.
The boot flag would be placed on sda2.
Additional repair would be performed: unhide-bootmenu-10s


=================== Final advice in case of suggested repair
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le disque sda (1000GB) !


=================== User settings
The settings chosen by the user will not act on the boot.

Cette installation de Ubuntu 16.04.1 est inhabituelle pour moi : elle est en LVM2
Le fichier grub.cfg utilisé au démarrage se trouve sur la partition racine : 

ubuntu-vg-root: ________________________________________________________________

    File system:       ext4
    Boot sector type:  -
    Boot sector info: 
    Operating System:  Ubuntu 16.04.1 LTS
    Boot files:        /boot/grub/grub.cfg /etc/fstab 
/boot/grub/i386-pc/core.img

Alors qu'il devrait se trouver dans la partition sdb1. Je pense que c'est une installation pourrie mais je n'en suis pas certain.

EDIT : fichier fstab extrait du Boot-Info : 

========================== ubuntu-vg-root/etc/fstab: ===========================

--------------------------------------------------------------------------------
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a

On voit que la ligne de montage de /dev/sdb1 dans /boot a été commentée (caractère # en tête) afin qu'elle ne soit plus prise en compte : 

#UUID=2d20eba7-1c9b-408e-ba80-ce427ae97436	/boot	ext2	defaults	0	2

Est-ce toi qui a ajouté ce caractère # en tête de cette ligne ?

Re : Démarrage sur DD en SSD pas très rapide

Salut Malbo,
merci en tout cas du coup de main. J'ai lu en diagonale ce qu'est le LVM2, pas tout tout compris mais en tout cas j'ai pas l'impression d'avoir fait quelque chose de particulier dans ce sens. En même temps c'est aussi quand on sait pas qu'on est le mieux à même de faire des choses bizarres. Je vais me tourner vers l'animateur de l'EPN du coin qui est un libriste hors pair, voir s'il y vois un peu plus clair (je sens déjà qu'il falloir que je fasse une réinstall...)
Merci bien.

Re : Démarrage sur DD en SSD pas très rapide

Oui, si tu as une installation en LVM2 et que tu ne sais pas pourquoi tu as ça, c'est surprenant.
En attendant, je te conseille de bien sauvegarder régulièrement tes données sur un disque dur externe(*). Le jour où ton installation actuelle deviendra complètement nase, tu pourras faire cette installation d'un Ubuntu tout neuf sans LVM2 (demande conseil ici pour qu'on t'aide à maîtriser la chose quand tu en seras là parce que ce serait couillon de remettre encore LVM2)

(*) c'est ce que tout le monde est sensé faire mais dans le cas d'une installation qui tient avec des bouts de ficelle comme la tienne, ça me parait encore plus important.

Bonjour
je me rend compte que mon DD de 750 Go qui contient ubuntu est nommé sdb alors que mon DD de 1To qui me sert juste de stockage de données est en sda. Est-ce que cet ordre des disque dur a une importance?
Tchaeroo

Bonjour
Lors de l'installation il faut relier le DD de 750 Go  par un 'câble'  a une prise de connexion sur la carte mère.
Lors de l'installation il faut relier le DD de 1000Go  par un 'câble'  a une autre prise de connexion sur la carte mère.
Ces prise de connexions sont numérotées de 0   à  N
Le câble relié au 0 donnera le nom SDA et l'autre SDB. Mais cela n'a aucune importance que cela soit l'un ou l'autre.

Pour le LVM, ce n'est pas surprenant aussitôt qu'il y a deux disques.  Cela ouvre la possibilité de définir un disque  virtuel dont la taille peut être égale là la taille des deux.... Gros  avantage tu disposes d'un gros espace pour stocker tes données. Gros inconvénient, si un disque est en panne, tu ne peux plus utiliser le second.  Autre inconvénient, la façon d'accéder aux disques n'est pas très classique. C'est plutôt dans le monde de l'entreprise qu'on rencontre cette structure qui est couplée à un logiciel RAIDS afin d'éliminer le problème de la panne disque.
Par exemple, je viens de découvrir que windows10 édition version familiale ne dispose plus de cette option RAID. Mais que l'édition entreprise en dispose  sous un autre nom et gère en standard jusqu'à 7 disques (D'après la doc)..

Re : Démarrage sur DD en SSD pas très rapide

Bonsoir Malbo
Si on regarde, le contenu des MBR , tu as raison,     probablement du boot-repare-LVM?...  ou un upgrade parfaitement réussi en version 16.04!!!!! Mais si on regarde avant, même si on voit du windows vista, il y avait du lvm assurément classique avec sa partition dédiée au boot comme tu l'avais remarqué.

montre qu'il y a un noyau 3.16.0-77 parmi les noyaux de Ubuntu 16.04 (4.4.0-36 et 4.4.0-38). On peut penser qu'il s'agit d'une mise à niveau vers 16.04 et non pas d'une installation toute neuve de Ubuntu 16.04. Pour moi, c'est mystérieux.

Re : Démarrage sur DD en SSD pas très rapide

Bonjour Malbo
Il est maintenant fort possible que la version 16.04 sache directement booter sur du lmv et n'ait plus besoin d'une partition de boot en EXT2 de taille tellement petite qu'il y avait plein de problèmes,  L'upgrade aurait alors bien rectifié.

Re : Démarrage sur DD en SSD pas très rapide

Tchaeroo,
Je suis parvenu à recréer une installation LVM2 sans partition /boot - en virtualisation - en procédant comme suit :
1) installation en automatique de Ubuntu 16.04.1 64 bits en LVM2 (deux cases cochées à l'étape "Type d'installation" : case "Effacer le disque et installer Ubuntu" et case "Utiliser LVM pour la nouvelle installation de Ubuntu")
2) installation "par dessus" de la même version mais en sélectionnant "Autre chose" à l'étape "Type d'installation" et en me contentant de modifier la partition racine (case formatage cochée) mais sans toucher à l'ancienne partition /boot de sorte qu'elle ne soit plus utilisée.
J'ai obtenu ce qu'on peut voir dans le Boot-Info http://paste2.org/4zxNNy96 que je colle ci-dessous :

=================== Suggested repair
The default repair of the Boot-Repair utility would purge (in order to enable-lvm) and reinstall the grub2 of mapper/ubuntu--vg-root into the MBR of sda.
Additional repair would be performed: unhide-bootmenu-10s


=================== User settings
The settings chosen by the user will not act on the boot.

On y voit bien les caractéristiques de cette installation daubique :
1) un chargeur d'amorçage qui pointe directement sur la partition racine : 

============================= Boot Info Summary: ===============================

 => Grub2 (v2.00) is installed in the MBR of /dev/sda and looks at sector 1 of 
    the same hard drive for core.img. core.img is at this location and looks 
    for 
    (lvmid/JWxGCL-2LJZ-j1w2-5sef-bG7a-1sqB-i7DE21/3ejZGl-E40t-PXqS-WLiZ-l8AR-LA
yQ-dr3jun)/boot/grub.

2) un fichier fstab qui ne comporte pas de partition /boot : 

========================== ubuntu-vg-root/etc/fstab: ===========================

--------------------------------------------------------------------------------
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
/dev/mapper/ubuntu--vg-root /               ext4    errors=remount-ro 0       1
/dev/mapper/ubuntu--vg-swap_1 none swap sw 0 0

J'ajoute que j'ai fait également une manip de tentative de mise à niveau 14.04 vers 16.04 d'un installation LVM2 dans laquelle j'avais bourré exprès des fichiers dans la partition /boot pour voir ce qui allait se passer : en fait, le logiciel de mise à niveau s'est bien comporté car il a signalé que la partition /boot était pleine et il a refusé de faire la mise à niveau. Cela me conforte dans l'idée que l'installation en LVM2 sans partition /boot est bien une installation indésirable et si un de ces 4 tu as des soucis avec ton installation, je te recommande de tout réinstaller au propre sans LVM2.
