comment Is it possible to add permissions to an Active Directory account using PowerShell?
Creating a group really is the best way. You really should avoid adding permissions directly to an individual account whenever you can.

comment Reverse Proxy multiple internal FTP Servers
Why ftp? Why not SSH/SFTP? SSH is more secure, and easier to get through your firewall.

comment Puppet change mysql datadir only if it is installed first time
Why are you creating a new mount at /mysql That is not a standard location, anyone using the FHS would look for something. I would expect data like that to be under /var, or possibly /srv/.

comment Server's free memory keeps reducing
Why would it. The point of a cache is to cache things. If the cache was immediately released, it wouldn't be a cache.

comment iptable rule and iftop command
Call your ISP, and have them block it on their equipment. Think it through. Your server cannot decide to block/permit something until it has already arrived. You of course could just turn off your server, then you won't get any packets.

comment iptable rule and iftop command
Depends on what you mean by 'stopping'. If someone is flooding you with packets they will still be delivered to your system. An iptables DROP rule prevents your system from doing anything with the packets, once they have arrived.

Have you tried booting into rescue mode? It should be one of the options at boot time.

comment No space left on device error
I don't know postgres, but if you are using standard packages, I highly doubt it is storing data under /etc.

comment No space left on device error
Why is /etc 3.7GB? That is an unusually large size for /etc.

comment mdadm: Disk configuration by UUID
I am not aware of it being deprecated. It just isn't necessary. The kernel will auto-discover a lot. AFAIK 99% of the time you don't need to use that. But I am sure there are situations where it wouldbe useful.
