Xen🔗

Add block storage to a live VM without downtime🔗

xm toolstack🔗

xm block-attach drupal9 phy:/dev/vg_xen25/drupal9_swap xvda2 w

xl toolstack🔗

First you need to find the domain ID:

xl list | grep rek-web01 | awk '{print $2}'

Let's say this spits out "46", and now you can add the block storage:

xl -v block-attach 46 phy:/dev/vg_xen1/rek-web01_swap xvda1 w
