Red Hat Summit5.3.2. Déplacer les données
Vous pouvez déplacer toutes les extensions physiques utilisées dans
/dev/sdc1 vers /dev/sdb1 avec la commande pvmove. La commande pvmove peut prendre du temps à s'exécuter.
[root@tng3-1 ~]# pvmove /dev/sdc1 /dev/sdb1
/dev/sdc1: Moved: 14.7%
/dev/sdc1: Moved: 30.3%
/dev/sdc1: Moved: 45.7%
/dev/sdc1: Moved: 61.0%
/dev/sdc1: Moved: 76.6%
/dev/sdc1: Moved: 92.2%
/dev/sdc1: Moved: 100.0%
Après avoir déplacé les données, vous remarquerez que tout l'espace sur
/dev/sdc1 est libre.
