When i Restart the drbd service then check the status # cat /proc/drbd
it shows ( Connected ro:Secondary/Secondary ) , so after doing the below:

drbdadm disconnect r0
drbdadm connect r0
drbdadm primary r0

and do the same on the other node but # drbdadm secondary r0
still the same i have no /dev/drbd0

@Adaministrator said in ubuntu server shutdown "failed to finalize DM devices" device stays on:

@scottalanmiller I couldn't find a way to mark the post as closed/ answered. Do I need to do anything to shut this one down?

It's currently marked as a discussion rather than as a question. In theory you can use the Topic Tools and "Mark as Question". Once it is a question, then you can go to an individual post and mark that one as the answer OR you can use the Topic Tools again and just mark it generically answered.

@r0dISK said in I did a thing, have a quick Linux question:

22TB ? mdadm + RAID6...

That's a lot to have under RAID 6, but for a home lab is fine.

@wirestyle22 Great!!

This was nowhere close. Mint couldn't even remotely try to boot. Ubuntu.... just worked. All it needed was...

nouveau.modeset=0

What do you think the holdup was?

That's an easy fix 🙂

Sweet laptop, post a review when you get it.

Good idea I will.

Been using Mint for the last few days, and I actually LOVE it!

I used Ubuntu for a while, but man Linux Mint is just easier and more streamlined...

it's really great. I've been on it for nearly a year and what a difference it makes.

What the heck is included in a 4GB hacking ISO!

Confirmed that this is working on Linux Mint 18.

@RobLewisss said in Linux Iptables Firewall Automation:

@JulianJulian Thanks mate! I just downloaded the agent. I'll let you guys know how it works.

I also downloaded the agent to one of my Linux systems. It was very quick and simple.

The cloud interface picked up the installed agent imediately and I was able to manage it right there.

There are different groups that you can place each agent for different rules.

Definitely worth testing. Up to 5 servers for free!

@scottalanmiller said in iscsi target Path configuration:

Last system I checked LVM and mapper were equal symlinks pointing to the same thing. I checked it because I was documenting on CentOS.

Still interesting. Device mapper is just that, a mapper pointing to LVM (and LUKS) devices for example. So your mapper and LVM are both pointing to something "physical" like md devices or sd*?

Both pointing to the dm device, which is another layer of mapping.
