Bonjour,
J'ai un (vieux) PC sous Gentoo que je trouve subitement (vraiment du
jour au lendemain) tr=E8s tr=E8s lent.
Pour vous donner une id=E9e de cette lenteur, habituellement, son backup
complet de 6Go par bacula se fait en 10mn environ. L=E0, il en est =E0
220Mo en 50mn.
J'ai d'abord pens=E9 que =E7a pouvait =EAtre un pb r=E9seau (il est en fila=
ire)
mais les tests que j'ai pu faire (simple wget gros fichier) n'ont rien
r=E9l=E9v=E9 d'anormal.
Ce n'est pas de la charge proc (un Quad core), un top ne donne rien du
tout.
Il ne s'est rien pass=E9 au niveau logiciel =E0 ce moment entre temps, pas
la moindre mise =E0 jour.
J'en d=E9duis que =E7a pourrait =EAtre un probl=E8me de lenteur disque.
Ce PC contient le premier SSD que j'ai eu, et je n'ai aucune exp=E9rience
de SSD d=E9faillant.
Le r=E9sultat d'un hdparm -tT /dev/sdb me laisse sceptique par rapport =E0
mes autres PC avec SSD :
/dev/sdb:
Timing cached reads: 2694 MB in 2.00 seconds =3D 1347.05 MB/sec
Timing buffered disk reads: 390 MB in 3.00 seconds =3D 129.87 MB/sec
Un smartctl -l ne m'indique rien de particulier =E0 mes yeux.

Est-ce un disque qui l=E2che ?
Je ne vois rien qui le dise, mais je ne vois que =E7a qui puisse =EAtre en
cause.
Merci d'avance.
