Changer un disque en command line

L’interface graphique de ssa est juste insuportable. Lancée avec # ssa -local, elle peut mettre énormément de temps à s’afficher via un navigateur, et énormément de temps à afficher les informations….

TL;DR

1/ Inspecter le disque (ici le 18) avec smartctl:

$ sudo /usr/sbin/smartctl -a -d cciss,18 /dev/disk/by-id/scsi-424242abcdef0123456789ab1337

2/ Vérifier qu’il s’agit du bon disque en comparant sont SN (Serial Number) :

$ sudo ssacli ctrl slot=0 physicaldrive 1I:1:18 show detail

3/ Localiser le disque

$ sudo ssacli ctrl slot=0 physicaldrive 1I:1:18 modify led=on
$ sudo ssacli ctrl slot=0 physicaldrive 1I:1:18 modify led=off

4/ Changer manuellement le disque

5/ État du RAID et du rebuilt :

$ sudo ssacli ctrl all show config

Détecter un disque défectueux

Inspecter le disque (ici le 18) avec smartctl:

$ sudo /usr/sbin/smartctl -a -d cciss,18 /dev/disk/by-id/scsi-424242abcdef0123456789ab1337

Exemple :
