Le montage de ce disque a été simple donc l'augmentation à chaud requiers plus de manips.

D'abord sur l'hyperviseur on augmente le lv concerné.¶

(April) root@galanga:~# lvresize -L+100G /dev/vg_galanga/borg_backup 
  /dev/sdc: open failed: No medium found
  /dev/sdd: open failed: No medium found
  Size of logical volume vg_galanga/borg_backup changed from 400.00 GiB (102400 extents) to 500.00 GiB (128000 extents).
  Logical volume vg_galanga/borg_backup successfully resized.

Arrêter puis redémarrer la VM contenant le disque retaillé.¶

Un simple reboot ne suffit pas, il faut éteindre la VM.

(April) root@galanga:~# virsh shutdown icinga2
Domain icinga2 is being shutdown

(April) root@galanga:~# virsh list 
 Id   Name   State
--------------------

(April) root@galanga:~# virsh start icinga2

Etendre la partition sur le disque¶

Le faire à chad nécessite de taper dans la table de partition : on delete on recréé. Il faut conserver le bon démarrage de la partition (ici 2048).

=(^-^)=root@icinga2:~# fdisk /dev/vdb 

Welcome to fdisk (util-linux 2.33.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
