Looks like Sangoma uses XFS on LVM, so for my new install of FreePBX 2020 which ran out of space:
- I ran gparted iso to expand the partition
- I ran lvextend –l +100%FREE /dev/mapper/SangomaVG-root –r to extend LVM to use the space
- THEN I had to run xfs_growfs /dev/mapper/SangomaVG-root -d for XFS on LVM to use the newly available blocks.
Thanks again for your help, couldn’t have done it without you!
