Extending disk space on OLVM hosted-engine
I've created a 100GB iscsi lun for the hosted storage domain.
During installation of the self-hosted engine, i choose the appliance, when asked, tell it to use 80GB.
When I log into the self-hosted-engine, and check, I see that it is only using 25GB.
Anyway to really use that "unused" space?
Can I extend the root VG/LV?
/var/opt appears to be the heaviest user. Is it possible to create a new vg/lv/filesystem and move the data of /var/opt to it, and then mount it on /var/opt? What do I need to be sensitive about?
