I downloaded some python script to convert the xva files to raw. I ended up just rebuilding them.

@gjacobse said in Korora 25 Daily Use:

It's been a bit since I mentioned my conversion to and use of Korora 25 as my daily OS for the NTG computer. I figured it was high time that I took a moment and mentioned what I have had issues with, and what I have not had issues with.

Using Korora 25 Daily has meant some adjustments were needed. I mean, we went from Windows 10 to Linux - there are going to be some differences.

• Browsers
  Yup, they work. Firefox, Google Chrome and Chromium. The only 'key thing' I didn't do moving from Win10 to Korora was to back up and move my bookmarks - easy enough to do at any time since Win10 is still here. I can boot it up at any time. It's honestly something I have been meaning to do - setup a backup / restore extension so that I have my bookmarks on whichever platform I am using at the time, or what ever computer. I mean, I have three running right here currently. Meh - I'll get to it sometime.

• ScreenConnect
  Well, it works - nearly the same as when it did on Win10 - so nothing really to report there. There are a few things that are different - but it's mainly 'appearance' only. All the functions are still there. Just the same adage as above. It's different - so it takes a little to get use to.

• Office / Email
  I can use LibreOffice, OpenOffice - and honestly I was already doing so on my personal laptop where I went so far as to default the SAVE AS to use MS format as just about every thing I do deal with for spreadsheets, word and such are in Office format. I honestly haven't done much document work on Korora yet,.. but as I have exposure to LibreOffice, it's not likely to be an issue.

• Audio / Telephone
  This is likely my biggest 'issue' and one I understand. I have a Jabra Pro 9400 series headset for my Yealink T22 desk phone. Making / Taking phone calls on the Yealink aren't any problem. It's solely independent of the computer. However when using Skype, I have to manually shift the Mic/Speaker since Jabra does not have the integration software available. It's available for Windows and MAC - but Linux. So I have to shift the audio settings when I use Skype for a call. The other part of the integration software is the ability to answer a call using the head set button. Since it's not on Linux, I have to be AT the computer to answer a Skype call. Disappointing - but not enough to send me packing back to Windows

• Workspaces / Monitors
  Yup, I'm using at least two of the four work spaces. Skype and the main browser is set to be on ALL workspaces while the Remmina RDP session to my laptop is set to use workspace 2, Monitor 2. The monitors are pretty much setup as they were in Win10 with monitor 3 on top and in the middle of 1 and 2. If I got off my duf, I could easily add one more monitor, but I don't have the cable needed and just haven't felt inclined to order it (yet).

• Mouse Scroll
  The only thing I can't do in LInux is use the Scroll wheel click. Now the scroll wheels works,... but in Win10 I could click it and then push the mouse up to get to the top of the page faster than scrolling. This doesn't seem to be possible (that I have found) in Linux. Yet when I control the Win10 box via Remmina - it does.

---

So with that, I have enjoyed using Korora 25 and will likely move my laptop to it shortly. The kid want's to build his own computer, so it will be dual booted as well so he can learn both.

That scroll wheel click features should be available in your mouse settings. I'll have to look on my Fedora 26 laptop but I'm pretty sure you can configure that in the settings menu.

I've never used it for that but I heavily use the middle click to paste highlighted text.

@francesco-provino said in Migrating away from XenServer:

@scottalanmiller so, your raccomandation for deploying a KVM host is fedora 26, because KVM it is RH baby and F26 is the most recent one?

That would likely be where I would go. Suse supports KVM pretty well, though. Either is fine. But definitely Fedora over CentOS / RHEL. I've stopped using them anytime that I have the choice. We've almost completely replaced our CentOS 7 boxes with vastly superior Fedora 26 boxes. There are a few cases where CentOS still makes sense like for Zimbra hosts. But by and large Fedora makes the better sense.

Those aren't hypervisor hosts though. There's a difference between state machines running Fedora and your host that the state machines are running on running Fedora.

Right, there is a difference, but for both you want stability, performance and features. I'd want Fedora in both cases.

I've had Fedora upgrades not go smoothly. So if that happens it's less stability than CentOS, esp since it's every ~8 months.

How have your CentOS updates gone? I've had far better luck with smaller, incremental Fedora updates.

Never had an issue with updates. And I'm not talking normal updates. I'm talking release upgrades that have removed features and broken backwards compatibility.

State machines sure run whatever the newest best because it's easy to rebuild. The host needs stability which I have had less with on Fedora than CentOS.

Right, and I feel that Fedora has the edge on stability now. Hence why I want Fedora under the hood. I don't want the massive LTS upgrade risks that CentOS brings. Not that it has no advantages, but I don't feel that they outweight the benefits any longer.

And you've never answered the question I've asked you before. What are you using for central logging on Fedora?

We've moved away from central logging temporarily during a major overhaul internally. Are you seeing issues with Fedora with central logging?

You pretty much can't unless you pipe journald into syslog and ship out that way. Which is 100% going backwards.

I don't like the way systemd handles logging (in Fedora).

Yeah, there have been loads of complaints about how Fedora is handling a lot of that stuff (and some other distros, too.) SystemD is not doing Linux any favours.

I like systemd if they would just leave the logging the way it is in RHEL/CentOS. It's nice being able to search specific time spaces but there isn't even a messages file in Fedora anymore.

@emad-r said in Centos Power Profiles?:

So I was playing with Kimchi and I noticed this, I supposed to be running Centos KVM host and not guest.

I researched and I dont want to read 1000 page from RedHat, I wondered anybody have more info about this, and is there CLI command where you can manage this ?

It's probably just an interface for tuned. The names look similar.

How big is your LV?

@tim_g said in Fedora 26 No Space Left on Device with Plenty of Space Available:

Seems weird to me that this can happen. This inodes thing is completely new to me. I had to look it up, and know almost nothing about it. Seems like a major Linux turn-off if this happens for no reason.

Maybe I need a good explanation, if someone doesn't mind.

This is the same limitation any FS has. It's just metadata. If you have a ton of files you will run out of available inodes. Containers are an area where this can happen easily since all of the containers can share the same FS as the host.

This is also usually more of an issue with EXT file systems (like we had here). INodes are set at FS creation and cannot be changed in EXT. Whereas XFS is dynamic (but has a limit that's based on percentage).

@wirestyle22 said in Fedora 26 No Space Left on Device with Plenty of Space Available:

So my question is: Why did a reboot fix this? @scottalanmiller's available inodes should be exactly the same, unless he has a container running that is creating and deleting files very frequently

Usually comes from orphaned INodes. Can happen if the process halts or server is shutdown incorrectly. This is what the lost+found directory is for.

Ya I've never run into it in the real world only on trick questions

I never saw the value in the USG. Maybe if you were doing full network automation and copying configs, and then that defeats the purpose of the USG anyway. I have an ERL and an EdgeSwitch Lite at home, along with 2 APs.

@scottalanmiller I could've sworn there was a post here related to a reboot solving it

Someone mentioned rebooting to try to solve it. But it did not (had already done that.) It was real files causing the issue, nothing orphaned. Literally, we were making 30K files an hour or so.

Tiny files to, right?

That is not relevant except for that fact that large files would have filled drive space and likely been noticed.

How is that not relevant? more files = more inodes being used

Size of the files is not relevant.

It actually makes sense that @scottalanmiller said it was mostly directories. Files of any size will almost always run out of drive space before inodes run out in 99.9999% of situations. This is the first time I've actually heard of this happening, ever.

Only not relevant for those who actually know about inodes already. The only reason I even know about them is they got mentioned in SGI's IRIX Sysadmin courses.

The one major exception is marker files. "touch thishappened" as a file automatically and never clean up and you are using inodes without using any space. That's who you can easily learn about inode depletion. But who does that?

People writing bad scripts that use lock files and forget to remove them.

That wouldn't create enough to do this though.

If you start using configuration management tools to manage infrastructure with code you get the chance to see some of these one-off oddities in the wild a little more frequently than you'd expect. Like having Java developers not use Java's log facilities to manage log rotation, and then having a generic log rotation configuration completely bork things by delete application logs that are still being accessed by the Java application.

I got to see this issue a few dozen times a few months ago before another of our Engineers disassociated the Java applications from our generic log rotation recipe.

Rebooting was the quick fix for us prior to fixing the actual problem.

Oh wow. Everything I have is managed with Ansible ( I can't even log in to servers), however all of the devs use Oracle APEX on separate systems so they don't really touch anything on my stuff. I'm sure I'd have it much worse if I had to manage their stuff.

Also since everyone was confused at the beginning about whether this was Linux or Windows, there is a utility for Linux called USBGuard. It will only allow trusted USB devices based on a white list and log all attempts. It's easy to automate also.

I would also try switching to a non pv driver. If it boots with a normal SCSI driver then it's probably virtio.

A VPN adds overhead and latency

You sir, have not seen what a pair of Brocade MLXe's can do with a dark fiber connection. A fully loaded chassis could push 1.2Tbps of IPSEC traffic at wire speed.

Shitty consumer grade, no crypto ASIC stuff? Yah, there are limits. The latency your complaining about? That's likely from trying to run UDP real time protocols WITHOUT configuring datagram TLS? OUCH. Yah that's gonna suck. Use a real VPN appliance that will support dTLS.

What is the cost of stuff like that? Recall that most people here come from SMBs where we are now recommending ER-L firewalls that cost $150 or less.

I don't think that was the point of his post.

my question still stands.

Expensive. But again, that wasn't his point. ASIC offloading and dTLS aren't only available in those. Ubiquiti does crypto ASIC. Last place I worked we did 3D CAD with SolidWorks over ZeroTier and it wasn't bad. There is likely some serious tuning that could be done here.

@jclambert said in With Crashplan Free/Home going away...:

I use the paid version of Crashplan at home. I script each laptop to backup data to a linux box which in turn connects to CrashPlan Pro. I only need to pay for a single seat. At around $10 for unlimited storage in this model, it works well enough

Same here but the systems use Deja Dup to backup with.

I was using the paid home subscription. I may just change to the business one. I don't know how much effort I want to put into something else.

I'm backing up enough data (1.7TB) that B2 would cost more than crash plan business and then there is the added cost of downloads on top of that.

Just switched to fedora and installed KVM. What is the deal with Boxes? Is it "enterprise"-worthy to learn?

Boxes is just a silly thing for using KVM on the desktop for a VirtualBox style replacement. I've not seen any value to it.

It does some kind of remote system control too according to what they say but I've never used it.

The big problem for me with the home version of BackBlaze is you can't install it on a Linux based system. Obviously I'm not their target market as I have no Windows or Mac systems at home, which is why I will probably just pay CrashPlan the extra money.

Exactly the same as an XPS but with higher specs

The XPS also comes in 15 inch if you don't need the "business" model.

Definitely overkill for normal office workers that are spending 90% of their day in chrome and the other 10% in Outlook.

The XPS 15" starts at $1000 and still doesn't have a 100% SSD in it I don't need a ton of storage!

Thanks for the link.

What good is an SSD for Chrome and Outlook? Seems like a waste of money.

The whole thing seems like a waste of money. If you are buying business grade laptops when they essentially need a chromebook, anything seems like a waste.

With essentially unlimited resources how are these contractors this bad?

“At no time was there ever a data breach of any TigerSwan server,” the firm said. “All resume files in TigerSwan’s possession are secure. We take seriously the failure of TalentPen to ensure the security of this information and regret any inconvenience or exposure our former recruiting vendor may have caused these applicants. TigerSwan is currently exploring all recourse and options available to us and those who submitted a resume.”

TalentPen could not be immediately reached for comment and Gizmodo could not independently confirm the company’s involvement. During conversations with Gizmodo, TigerSwan repeatedly refused to provide any documentation showing TalentPen was at fault.

Oh yeah I believe you. It's the other guys fault, but we won't show you any evidence it was....
