Hi @k0ns0l3,

This tmpfs is meant to speed up processing writing/ingesting reporting logs; and saves a considerable amount of disk I/O in large networks.

In small networks, it might not be too important. We can make this a configurable setting.

Quick question: what is the reason you want to remove it?

Hi mb  8)

I tried Sensei and uninstalled again so do not need anymore swap (Two are unnecessary)  ;)

Thank you and best regards 8)

how did you remove Sensei/ZenArmor?  IIRC the pkg remove *SHOULD* delete the tmpfs.

Zenarmor-Sensei→Configuration→Uninstall on your OPNsense GUI —> Uninstall Zenarmor Packet Engine

I hope it's the right way  :)

@lrosenman thanks.

@k0ns0l3 run below command on the console, that should unmount the file system.

Code: [Select]

/sbin/umount /dev/md43

Followed by

Code: [Select]

mdconfig -d -u 43
What I simply don't know is, whether the RAM disk will be recreated at reboot.

Well, nothing in core/plugins creates memory disks so this must be an extra script left behind somewhere in /usr/local/etc/rc.syshook.d ...


# grep -nr mdconfig /usr/local/etc/rc.syshook.d

I didn't notice anything unusual  :-\

in my eyes this is a bug at installation and uninstall from    
Zenarmor (Sensei)

I must admit I haven't read all of the thread but the question is: if it sticks after reboot it's a leftover script somewhere, isn't it?

Hi @k0ns0l3

/dev/md98 did not seem familiar to me. Zenarmor's memdisk device is  /dev/md43.

Let me check with the team again.

Other than that, zenarmor's memdisk should not survive reboots unless you have the Zenarmor Packet Engine is set to be enabled at boot time. Memdisk is created by the rc service script.

Hi @k0ns0l3

Checked this with the team. /dev/md98 is not related to Zenarmor.

Maybe some other plugin is creating that?

Anyhow feel free to reach out to the support. Team will be happy to have a look.
