Salt only affects online minions. There are no cached actions.

Not having used salt yet myself, couldn't you set the contents of that file using the Salt Master?

I'll add a note for clarity given the title... SaltStack does not do authentication like AD does. AD does not do patching of any sort like Salt does. Salt is an alternative to common myths about AD functionality, but not to actual AD functionality. But you can use Salt to do distributed local authentication management, which does replace the need for AD, but is very different than what is being discussed here. In this case Salt is replacing GPO, not AD.

@scottalanmiller

ohh shit, how did that get passed me...

Great, thanks again.

🙂

I believe that your cp.get file should be something like:

salt * cp.get_file salt://test123.txt C:\

You can also do this with the file.managed in a state file.

C:\zabbix_agent\zabbix_agentd.conf: file.managed: - source: - salt://zabbix/zabbix_agentd.conf - user: root - group: root - mode: 644

@pchiodo

Yup there is :

suprised to find this actually...

It's pretty easy at the network level, just look for DHCP traffic from one that one source.

So much for Cisco Over Engineering products

Um.... do people actually think that?

I think I got it working with Ubuntu LTS 16.04.2 currently installing the system will see how it goes, however it does make sense that OS needs to be in-charge of this.

MD RAID

People rave about the new features of BTRFS so I thought can I do it for a new production server in 2017, perhaps I thought by now we will have more people tested it.

They sure do. Phoronix over the weekend: Btrfs Getting RAID 5/6 Fixes In Linux 4.12 Kernel

Got more usefull info, it seems it is cause of my -c switch:

https://docs.fedoraproject.org/en-US/Fedora/18/html/Virtualization_Administration_Guide/sect-Virtualization-Tips_and_tricks-Using_qemu_img.html

Convert

The convert option is used to convert one recognized image format to another image format.
Command format:

qemu-img convert [-c] [-f format] [-o options] [-O output_format] filename output_filename

Convert the disk image filename to disk image output_filename using format output_format. The disk image can be optionally compressed with the -c option, or encrypted with the -o option by setting -o encryption. Note that the options available with the -o parameter differ with the selected format.

Only the qcow2 format supports encryption or compression. qcow2 encryption uses the AES format with secure 128-bit keys. qcow2 compression is read-only, so if a compressed sector is converted from qcow2 format, it is written to the new format as uncompressed data.

Image conversion is also useful to get a smaller image when using a format which can grow, such as qcow or cow. The empty sectors are detected and suppressed from the destination image.

@iroal
Great minds think alike !

Thanks for the addition, I'm researching right now and blat.exe seems very worthy looking and simple with good reviews on its Sourceforge page:
https://sourceforge.net/projects/blat/

That's very odd. I, personally, haven't had good luck with the gui partition manager. For some reason it seems to work differently than what I think it's telling me. Can you boot to a rescue environment and create the RAID array and partitions before starting the installation?

@scottalanmiller said in Hyper-converged infrastructure (I missed the storage part):

Then look at someone like @scale who implement their own storage system directly on the hypervisor itself. So the hypervisor is the only component that needs to be spread out to many nodes. It's kind of like DRBD, being in the hypervisor, but is scale out rather than just a two node mirror. The storage and the hypervisor and the management are all really one thing. Very tightly integrated.

I did something similar. I had Gluster running between the hosts and the VMs are stored on the bricks. However I've switched to just running Gluster in the VMs that need replication. Most are replicated at the application level but a few need data replicated.

@JaredBusch said in How to tune or optimize MySQL or MariaDB ?:

Exactly. The ScreenConnect server performs like crap on Linux compared to Windows. But the problem is not the database. It is the .NET framework.

Right, I could totally see there being an application layer issue. Or a hardware problem. Or the system just being over-taxed. So many options. But that MariaDB isn't "tuned" for this, that's not a possibility. We'd measure the database response time for this in milliseconds, not seconds. And only sixty records? I've got MySQL on ancient systems with a fraction of these resources that will return literally millions of records in less time than that.

Safe mode should not affect disk drivers. If it did it could not attempt safe mode at all.

That was an easy one 🙂
