Does anyone know how to remove the SWAP created by Sensei?
Thank you and best regards

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

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

Thank you and best regards

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

check and see if the plugin is still installed.

I'm out of ideas.

@franco, @mb, @sy?

@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

Cheers,
Franco

@Franco

Code: [Select]

grep -nr mdconfig /usr/local/etc/rc.syshook.d
root@OPNsense:~ #

Code: [Select]

/usr/local/etc/rc.syshook.d # ls
backup	carp	early	monitor	start	stop	update

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?

Cheers,
Franco

at the moment I am overwhelmed myself and find no solution,in any case, this is not a clean uninstall of Zenarmor

now I have two swap
