Re: [monit] can't monitor one of my filesystems

[Martin Pala]

Hi,

LVM shouldn't be problem, please can you provide output of "ls -l /dev/sda2"? 
Which monit version do you use? There was problem in monit <= 4.10.1 when the 
device was symlink - the support for device symlinks was added in Monit 5.0 
(current version is Monit 5.1.1).

Optionally you can use mount point instead of device.

Regards,
Martin
