comment raid5 array reassembles as raid0
The answer in the link you referenced is what you need to do. I can't answer why raid5 would change to raid0, but that really shouldn't happen and is probably more of a red herring.

comment raid5 array reassembles as raid0
If you created a raid array as raid-5 it should never change to raid-0. The /proc/mdstat entry should show a raid personality, right now it is showing nothing. The disk signature shows that the disk thinks that it belongs to a RAID group, and that is good. You should be able to feed that information to mdadm and have it build/rebuild an array with those parameters.

comment raid5 array reassembles as raid0
I just read through your question and I'm having a lot of trouble understanding what you are trying to do. Right now you have three disks in a 3 disk Raid-5, what is the problem with that?

comment Intermittent Network disconnection, Ubuntu, troubleshooting help
Typically the "No buffer space" condition occurs when a NIC is unable to send data to a host. If you check your ping times you should be able to correlate increased ping time and/or packet loss with the error message.

comment How does the kernel prevent a malicious program from reading all of physical RAM?
You should read about page-tables and kernel abstraction there-in.

comment How do i force shut down on a computer without on off button
An unrelated note: Holding just Refresh and poking the Power button hard-resets the machine without entering Recovery. That's occasionally useful, but use it with care - it doesn't sync the disk or shut down politely, so there's a nonzero chance of trashing the contents of your stateful partition. -- chromium.org/chromium-os/…

comment Linux does not reply to ARP request messages if requested IP address is associated with another (disabled) interface
Having the same IP on two interfaces can create issues and is best avoided, that being said you should be able to trace down the issue. The next step is to look at the arp cache, does arp -a show anything useful?

comment Unable to mount a partition on an SSD over USB
The output you posted shows the disk as being at sde1. Otherwise everything looks good.

Can you paste the output of netstat -rn for both cases? The routing table is typically the first place to look for these sort of errors.

What VPN are you using. Both OpenVPN and OpenConnect work fine for me.

comment Audio not working on Arch Linux
The poster did mention that he installed ALSA which implies that it is not default. Archlinux does install pulse-audio by default thus it is likely to work as a mixer where as ALSA probably will not.
