Hallo,

hier hatte ich mal gezeigt wie ein LVM vergrößert werden kann.

http://konkretor.blog.de/2013/06/21/lvm-vmware-speichervergroessern-16151980

Heute will ich zeigen wie ein LVM überhaupt angelegt werden kann.

Tools die man dazu braucht

pvdisplay
vgdisplay

This filesystem will be automatically checked every 21 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.

mkdir backup

mount /dev/VolumeGroup01/backup backup

Danach noch in /etc/fstab

den Mountpoint noch eintragen
