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

[zachlac]

sda2 cannot be monitored, while sda1 can:

# ls -l /dev/sda2
brw-r----- 1 root disk 8, 2 Feb 19 14:22 /dev/sda2
# ls -l /dev/sda1
brw-r----- 1 root disk 8, 2 Feb 19 14:22 /dev/sda1

I'm using the repository version of monit, which is 5.2.

Thank you.
