re,
Pour moi il te manque l'option "default".
Ton disque dur est un SSD? Car il semble que ton fstab soit optimisé
pour les ssd? Si c'est le cas voici un passage de
https://wiki.archlinux.org/index.php/Solid_State_Drives
Si c'est un ssd met les options defaults,relatime,discard
Tips for Maximizing SSD Performance
Mount Flags
There are several key mount flags to use in one's /etc/fstab entries
for SSD partitions.
noatime - Reading accesses to the file system will no longer result in
an update to the atime information associated with the file. The
importance of the noatime setting is that it eliminates the need by
the system to make writes to the file system for files which are
simply being read. Since writes can be somewhat expensive as mentioned
in previous section, this can result in measurable performance gains.
Note that the write time information to a file will continue to be
updated anytime the file is written to with this option enabled.
However, this will cause issues with some programs such as Mutt, as
the access time of the file will eventually be previous than the
modification time, which would make no sense. Using the relatime
option instead of noatime will ensure that the atime field will never
be prior to the last modification time of a file.
discard - The discard flag will enable the benefits of the TRIM
command as long as one is using kernel version >=2.6.33. It does not
work with ext3; using the discard flag for an ext3 root partition will
result in it being mounted read-only.
/dev/sda1 / ext4 defaults,relatime,discard 0 1
/dev/sda2 /home ext4 defaults,relatime,discard 0 2
Warning: Users need to be certain that kernel version 2.6.33 or above
is being used AND that their SSD supports TRIM before attempting to
mount a partition with the discard flag. Data loss can occur otherwise!
Wouha! J'avais entendu dire que le wiki de arch linux était plutôt bien
foutu. Là c'est parfait!
Changement effectué selon les conseils.
Du coup je trouve que la doc de ubuntu-fr devrait être plus explicite.
Celle ssd_solid_state_drive est très précise (pointilleuse) mais on ne
trouve pas ce simple conseil: quels flags dans /etc/fstab?
De l'autre côté, sur la page de fstab, aucune info sur la configuration
avec un ssd.
ça mérite un ptit edit non?
