Just installed LVM Raid 1 on a new server with 2x 10Tb hard drives and the Disk I/O is killing everything else every second

I copied a bit of data on my LVM based RAID1 (not hardware RAID) with 2× 10Tb hard drives:

/dev/mapper/users-users  9.1T  1.9G  8.6T   1% /home 

and now it’s killing my I/O to the point where my mouse, keyboard, video are blocked/unblocked/blocked/unblocked…

I’m thinking that maybe something is wrong at the hardware level but wondering what that could be. Wondering what to test first to try to make a better diagnostic.

I have another 2 drives in the same drive array but they are not setup in RAID mode.

Looking at the output of iotop it tells me that there is about 2Mb/s written to disk, a pretty much permanent write… When I look at the Disk LED, I can see them come up and out over and over again and can hear the seeking heads too.

Trying to watch a video, it fails really bad. Choppy would not even be the word here. It’s like one image every other second if even that much. So a really big I/O killer for the entire computer.

Wondering whether someone would have encountered such a problem before and what can be done to fix it if possible (I certainly hope it is possible!)

My motherboard is a Supermicro X11DPH-T and I also got a case from Supermicro the 745BAC-R1K28B2 4U Full Tower Chassis. I’m running Ubuntu 18.04 LTS. The server is new and so is the install (i.e. not an upgrade from 16.04 or who knows what…)

Would there be a way to know whether a specific hard drive or some other hardware device is causing the trouble?

sound is not coming out, but everything (alsa mixer etc…) seem to show that it is working fine!

Samsung notebook 9 pen (2019) seem to have an issue with all linux distros regarding sound. I don’t see any errors regarding sound in dmesg or anywhere for that matter. Sound settings in all distros shows as normal (e.g. from fedora 30 kde), but I’m no expert so please point out if this screenshot is showing an issue to be fixed: Fedora 30 KDE

Ubuntu (all flavors) also have this issue. Tried with original ISOs as well as updated kernel 5.x while trying different distros. Any help is appreciated.

Teleport everything in a large zone; or teleport all living things and make a lot of equipment disappear

Imagine a traveling party of about 30 people, animals, wagons, and a bunch of equipment (e.g. think traveling theater). I’m trying to come up with a way for a devilish entity to teleport all of that away (on the same plane); or alternatively, teleport everybody and their animals, and then make all of their things disappear. The kidnapping happens in the night, while everybody is sleeping. A few constraints, for my scenario idea to work:

  • It needs to happen relatively discreetly, people a few hundred meters away shouldn’t notice that anything is happening (it can’t do too much noise, setting everything on fire is not an option);
  • It should leave no obvious trace; people who would look at the scene afterwards could fine clues, but nothing too obvious.
  • It should be compatible with the powers of a spellcaster devil of CR level between 9 and 11; maybe with a significant preparation time and resource consumption (burning scrolls, etc.), as well as assistance from a few minions.

Existing spells seem ill-suited for this, teleporting unwilling people is hard and requires high-level spells. But maybe there’s a creative way to do this e.g. with mind control, or minions with the right skillset?

What is it called when spouse calls, But always denying everything

what is it when your spouse is being very secretive, multiple phone lines, calling different phone numbers, on phone maybe 12 – 30 sec. But always denying everything. Some numbers are local. When I call them it has a fake business like Verizon help desk, I don’t know if they are doing VM or what..been married 34 wyears and now separated. Swears they are not cheating . Gets on this site from Russia called 1c connect. Anyone?

I removed x permission from everything, can I recover my error?

So I made a stupid error in a command and ran chmod -x -R / I can not run any commands that I can tell.

Is there a way to recover? workaround to get system functioning again?

I have backups but did not make one since some changes were made in the past week. Yes, dumb mistake. I am currently SSH into the remote server. I do not want to disconnect unless I have to. I am using aws services.

403 Forbidden Error Apache2 Ubuntu (Tried everything and all solutions I’ve ready.)

I know that this has been posted about A TON, but I have spent the last day scouring through answers, trying everything and nothing is working. I’ve changed permissions, I’ve looked into the Apache2 logs, I’ve altered configuration files, and I’m still getting the 403 forbidden error. Here are the apache2. My html files are in /var/www/html

I’m not completely sure, but I do recall troubles starting after trying to create user directories using: sudo a2enmod userdir

In side the apache error logs, the only thing on there that could be leading to something is this:

(13)Permission denied: [client myip] AH00035: access to  /folder/data/index.html denied (filesystem path  '/var/www/html/folder/data/index.html') because search permissions are  missing on a component of the path 

In my /etc/apache2/sites-available/000-default.conf, I added the following at the very end:

<Directory /var/www/html> AllowOverride All </Directory> 

In my apache2.conf I have the following:

<Directory />         Options FollowSymLinks         AllowOverride None         Require all denied </Directory>  <Directory /usr/share>         AllowOverride None         Require all granted </Directory>  <Directory /var/www/>         Options Indexes FollowSymLinks         AllowOverride ALL         Require all granted </Directory>  <Directory /var/www/html>         Options Indexes FollowSymLinks         AllowOverride ALL         Require all granted </Directory>  Again, I'm VERY sorry that I needed to make this thread, but I don't want to continue to copy and paste solutions that could do more harm than good. 

Is it a bad idea to push everything in my home folder to a private repo on GitHub?

And if so, why?

I have two ubuntu 18.04 machines that I use for work. One at home and one in the office. I use git and github a lot already. I make configuration changes to files in my home directory often (eg, .pgpass file for postgres etc) and I want those changes replicated between the machines, without me having to remember to explicitly sync them when I leave each one. Using source control makes sense to me, as I want to be able to rewind changes if I mess something up.

However, I’m worried that if I set up a process to sync everything in my home folder, I might accidentally push files that I shouldn’t (eg passwords). I know that I can tell git to ignore everything except the files I explicitly tell it to stage, but then I would lose the option of having it automatically sync everything. Is there a simple git ignore file pattern that would suit my needs?

I would rather not set up a private repo server as I then have to worry about keeping it running.
