LVM graphic not showing all data on Ubuntu 20

Closed this issue · 1 comments

When processing LVM data into graphics, if the distro is Ubuntu 20 onwards the mountpoints will be missing.
This doesn't affect the LVM overall display, but just bypassing some useful information

Issue caused by how Ubuntu displays LV data by default.
Fixed by forcing collection with:
lvs -a -o +devices,stripes,stripe_size,segtype
