Lenteur au démarrage / Pb de swap

Judophoniste

Salut tout le monde,
tout a commencé parce que mon disque dur(mécanique) faisait beaucoup de bruit pour rien...
J'ai supprimé la partition swap, et je pense avoir réussi à créer un fichier systemd-swap.
Par contre, c'est la galère pour que Ubuntu démarre rapidement :

sylv@syvio:~$ systemd-analyze time
Startup finished in 35.308s (kernel) + 3min 3.262s (userspace) = 3min 38.571s
graphical.target reached after 1min 47.369s in userspace

Help please!
Merci d'avance!

Bonjour,
Je te prie de passer la commande suivante dans un terminal :

cat /etc/initramfs-tools/conf.d/resume

Et de donner le retour complet de cette commande dans ta réponse.

Judophoniste

Merci pour ta réponse. Ça donne ça :

sylv@syvio:~$ cat /etc/initramfs-tools/conf.d/resume
RESUME=UUID=ab200ae2-b8d4-486f-816f-fd2952dbbeb2

malbo

Tu vas pouvoir appliquer la solution décrite par rotsen dans ce post : https://forum.ubuntu-fr.org/viewtopic.php?pid=22036620#p22036620
C'est le début du post qui est à prendre en compte :
---------------------------------------------------
Je viens de résoudre mon problème à l'aide de ce fil
c'est-à-dire en modifiant le fichier

/etc/initramfs-tools/conf.d/resume

de la façon suivante :

RESUME=none

et ensuite appliquer le changement :

sudo update-initramfs -u

--------------------------------------------------------------------------

Judophoniste

Hélas, je viens de faire la manip, mais ça ne change rien :

sylv@syvio:~$ systemd-analyze time
Startup finished in 2.707s (kernel) + 3min 3.182s (userspace) = 3min 5.890s
graphical.target reached after 1min 49.089s in userspace

🙁

P.S : je m'aperçois que quand je fais (en lisant la docu sur swap

sudo swapoff -av

j'ai

swapoff UUID=ab200ae2-b8d4-486f-816f-fd2952dbbeb2
swapoff: impossible de trouver le périphérique UUID=ab200ae2-b8d4-486f-816f-fd2952dbbeb

Je tatonne, je tatonne....

Bonjour,
Ce qui a changé, c'est le temps "kernel".
Dans le post #1, on avait :

Startup finished in 35.308s (kernel)

Alors que dans le post #5, on a :

Startup finished in 2.707s (kernel)

La manip que je t'ai proposée dans le post #4 était donc nécessaire.
Pour voir s'il y a une anomalie ailleurs, je te prie de faire un Boot-info depuis une session de ton Ubuntu installé et de donner l'URL de ce Boot-info dans ta réponse.

Judophoniste

Merci de te préoccuper de mon problème!
Voilà le boot-info : http://paste.ubuntu.com/p/VV36RM3qW9
A très vite!

Ton Boot-info est là :

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub2 of sda1 into the MBR of sda.
Additional repair would be performed: unhide-bootmenu-10s


=================== Final advice in case of suggested repair


Les fichiers de dÃ©marrage de [L'OS actuellement utilisÃ© - Ubuntu 18.04.3 LTS] sont loin du dÃ©but du disque. Votre BIOS pourrait ne pas les dÃ©tecter. Vous voudrez peut-Ãªtre re-essayer aprÃ¨s avoir crÃ©Ã© une partition /boot (EXT4, >200MB, en dÃ©but de disque). Cela peut Ãªtre rÃ©alisÃ© via des outils tels que gParted. Puis sÃ©lectionnez cette partition via l'option [Partition /boot sÃ©parÃ©eÂ :] de [Boot-Repair]. (http://doc.ubuntu-fr.org/tutoriel/partition_boot)


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

L'anomalie est dans le fichier fstab :

============================== sda1/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>
# / was on /dev/sda1 during installation
UUID=0bbba0b0-9e86-4510-abcc-00870aae5470 /               ext4    errors=remount-ro 0       1
# swap was on /dev/sda5 during installation
UUID=ab200ae2-b8d4-486f-816f-fd2952dbbeb2 none            swap    sw              0       0

l'UUID ab200ae2-b8d4-486f-816f-fd2952dbbeb2 n'existe pas (ou plus). Il va falloir commenter la ligne suivante du fstab :

UUID=ab200ae2-b8d4-486f-816f-fd2952dbbeb2 none            swap    sw              0       0

c'est à dire ajouter le caractère #en tête afin qu'elle devienne :

#UUID=ab200ae2-b8d4-486f-816f-fd2952dbbeb2 none            swap    sw              0       0

ce faisant, cette ligne ne sera plus prise en compte.

Pour éditer ce fichier fstab, tu trouveras des indications dans "Exemple pour éditer le fichier /etc/fstab" du paragraphe 2.2.1 Édition avec privilèges de la doc gedit.

Judophoniste

Ouhaou, merci MacGyver!
Maintenant :

sylv@syvio:~$ systemd-analyze time
Startup finished in 2.874s (kernel) + 30.224s (userspace) = 33.099s
graphical.target reached after 29.124s in userspace

Mais en vrai, je viens de chronométrer, c'est plus dans les 1m45 que l'ordi s'allume, tout en faisant un gros bruit de disque dur qui gratte.
Ces bruits se sont amoindris avec le fait qu'il n'y ait plus de partition swap, mais le démarrage galère donc encore un chouille...
Si tu as une dernière idée...
Et vraiment 1000 mercis!

Disque dur qui gratte, pas bon.

Pour moi, ton résultat du post #11 montre un disque dur en pleine forme.
Je n'ai plus d'idée. Peut-être qu'un autre aidant du forum sera plus inspiré que moi.

Judophoniste

Un immense merci en tout cas !!! Heureusement qu'il y a des gens comme toi 😉

Judophoniste

Je ne lâche pas l'affaire.
J'ai suivi cette procédure : https://doc.ubuntu-fr.org/tutoriel/partition_boot pour repartitionner mon disque et avoir la partition boot en début de disque. Je coyais que ça allait accélerer le démarrage, mais non, ça l'a rallongé :

sylv@syvio:~$ systemd-analyze time

Bonjour,
en passant à la 20.04, mon souci demeure. L'ordi est plus rapide une fois allumé, gratte moins. Mais il est toujours long et gratte au démarrage.
Quelqu'un aurait-il encore des idées?
D'avance merci.
