Health Monitor

[Leckey]

Hi all,

Having an odd problem with the health monitor. I've enabled disk monitoring on /var (or rather, /dev/mapper/vg00-var).
I'm trying to get it to execute:

lvextend -L +10G /dev/mapper/vg00-var && xfs_growfs /var

once the disk usage on that partition reaches 80%.

However when I click "OK" I get:

Error: Some defined attributes are incorrect.

Anyone what I'm doing wrong? Command is tested and works as expected.
