Disk mount related log entries

Hi all,

I started looking into logging more and I found these two messages marked as critical which is strange:

2016-11-25T22:25:54+01:00 crit mountd[2222]: Starting OpenWrt (auto)mountd V1
2016-11-25T22:25:54+01:00 crit mountd[2222]: trying to mount /tmp/run/mountd/ as the autofs root

And then there are messages about mounting NTFS volume. The strange thing here is that I don’t have any disk with NTFS attached. At the moment I installed just internal mSata disk and it is formatted as btrfs …

2016-11-25T22:25:56+01:00 emerg sfpswitch.py[1540]: Mount is denied because the NTFS volume is already exclusively opened.
2016-11-25T22:25:56+01:00 emerg sfpswitch.py[1540]: The volume may be already mounted, or another software may use it which
2016-11-25T22:25:56+01:00 emerg sfpswitch.py[1540]: could be identified for example by the help of the 'fuser' command.

Everything seems to work fine however I’d like to understand the logs as they might indicate an issue. My guess is that the NTFS related messages might be associated with these mount commands I put into rc.local

mount -o subvol=lxc-var /dev/sda /srv/lxc/var
mount -o subvol=omnia-logs /dev/sda /srv/omnia-logs

That’s just a guess - just because the messages about NTFS disks appeared twice and I have two btrfs subvolumes mounted …

Any other explanation about these logs?
Thanks.
