btrfs scrub complete

This was the status at the end of the scrub:

[root@supermario ~]# /usr/sbin/btrfs scrub start -Bd /media/Photos/
scrub device /dev/sdd1 (id 1) done
 scrub started at Tue Mar 21 17:18:13 2017 and finished after 05:49:29
 total bytes scrubbed: 2.31TiB with 0 errors
scrub device /dev/sda1 (id 2) done
 scrub started at Tue Mar 21 17:18:13 2017 and finished after 05:20:56
 total bytes scrubbed: 2.31TiB with 0 errors

I’m a bit perplexed at this information. Since this is a RAID1, I would expect it to be comparing info between disks – is this not so? If not, why? Because I would have expected both disks to end at the same time. Also, interesting to note that the 1TB/hr stopped being the case at some point.

Speed of btrfs scrub

Here’s the output of the status command:

[root@supermario ~]# btrfs scrub status /media/Photos/
scrub status for 27cc1330-c4e3-404f-98f6-f23becec76b5
 scrub started at Tue Mar 21 17:18:13 2017, running for 01:05:38
 total bytes scrubbed: 1.00TiB with 0 errors

So on Fedora 25 with an AMD-8323 (8 core, no hyperthreading) and 24GB of RAM with this hard drive and its 3TB brother in RAID1 , it takes about an hour per Terabyte to do a scrub. (Which seems about equal to what a coworker told me his system takes to do a zfs scrub – 40ish hours for about 40ish TB)

SuperMario is at Fedora 24

My main computer is now on Fedora 24. This time around I only had to uninstall HDR Merge (which was from my COPR and I hadn’t built a Fedora 24 version yet) and OBS-Studio because there isn’t a Fedora 24 package for it yet. Not bad.

After rebooting, I didn’t have graphics. Then rebooting once more kicked the akmod into gear and now things appear to be working well. 2 more computers left to upgrade to Fedora 24 – the VM server and the Kodi living room box.

Thank You OBS Developers

A quick thank you to the developers of OBS for adding the latest features in OBS Multiplatform 0.13.1. It was already a great platform, but with Studio Mode and video sources starting anew when going to a scene, it is near perfect for my use. All this by volunteers and for all three major OS platforms: Windows, Mac, and Linux! It is now extremely competitive against XSplit and competition among software devs always leads to better stuff for users!

Fedora and Dell Inspiron 17

I recently had to reinstall an OS on the wife’s Dell Inspiron 17. I was unable to complete an install for Fedora 22, but Fedora 21 and Fedora 23 beta were able to install. It would always freeze mid-install – usually around 70 or 80%. From what I could gleam on the net, it has to do with a kernel issue. But I’m not 100% sure. Anyway, just putting this out there for anyone trying to get Fedora 22 on a Dell Inspiron 17.

Neat KDE Connect Behavior

I have KDE connect installed on my computer and phone. KDE connect allows phone alerts to appear on my computer – letting me see if I’m getting a text or something. It just went off, letting me know I had a phone call. What’s neat is that I was listening to music and it paused the music until the phone call was over. While there might be some circumstances where that wouldn’t be the best default (say a party where I was playing the music), it’s certainly neat in the context of a personal computer.
