I set up PMM in a virtual machine and whilst all works nicely, there seems to be a cronjob running every 5 minutes that tries to resize /dev/sdb. As I understand it's meant to resize the disk automatically when you change its virtual size.
The problem however is that it's sending cron mails to the root user every 5 minutes, whilst not actually doing anything.
Cron <root@pmm> /var/lib/cloud/scripts/per-boot/resize-xfs
