– Expand the virtual disk in Virtualization Software
– Reboot Server for recognizing the new disk size
– delete the partition via fdisk and recreate it with new size
– resize2fs resize filesystem

for example resize sdb disk:
[root@kot ~]# fdisk /dev/sdb
(you can type m for help)

type "p" for showing the partition table, after evaluating the number of the partition type
d (for delete) and enter the partition number
After deleting the old partition type n for creating a new one
p for primary
For first cylinder i chose default setting (1)
For last cylinder I also used default setting
w for write

After that reboot, and after the reboot type resize2fs /dev/sdb(1) so the partition can extend. Check via df, the partition should now have the new size.

Unfortunately a Linux in german:

I liked Command and Conquer when I was younger. As nowadays Realtime Strategy has become a niche and not much good games at the market i checked out the Early Access Version of „They are Billions“. Its worth a look:

untony,
Today we are announcing changes to the YouTube Partner Program (YPP). While our goal remains to keep the YPP open to as many channels as possible, we recognize we need more safeguards in place to protect creator revenue across the YouTube ecosystem.
LEARN MORE
What’s Changing
Under the new eligibility requirements announced today, your YouTube channel, untony, is no longer eligible for monetization because it doesn’t meet the new threshold of 4,000 hours of watchtime within the past 12 months and 1,000 subscribers. As a result, your channel will lose access to all monetization tools and features associated with the YouTube Partner Program on February 20, 2018 unless you surpass this threshold in the next 30 days. Accordingly, this email serves as 30 days notice that your YouTube Partner Program terms are terminated.
One of YouTube’s core values is to provide anyone the opportunity to earn money from a thriving channel. Creators who haven’t yet reached this new threshold can continue to benefit from our Creator Academy, our Help Center, and all the resources on the Creator Site to grow their channels. Once your channel reaches the new threshold, it will be reviewed to make sure it adheres to our policies and guidelines, and if so, monetization will be re-enabled.

The threshold of 4000 hours wouldnt be a problem, but I dont have 1000 subscribers. So the time is over for me earning money via youtube.

As DASH-Mining becomes more and more unrentable (New ASIC-Miners, growing difficulty see screens below), I was looking for alternatives.

Dash GPU-Mining in June 2017:
Dash GPU-Mining in September 2017:

Hashflare 25 MH/s:

Dash Mining is not interessting for me anymore (dont want to buy expensive mining hw at this time).

Currently the only rentable Cryptocurrency for mining seem to be Monero. Also because it is more rentable to use CPU-Miners (in comparism to other Cryptocurrencies).


Not beeing forced to use GPU Miners (with AMD GPUs) to get coins is a big plus. I installed some miners on Linux-Systems (also virtualized). I poolmined (monerohash.com) for a few days with   5 CPU Miners. Here some results:

Physical System (CPU Intel Core Duo using 3 threads): 23.95 H/s at diff 5000
Virtual Machine(Host CPU: XEON X5560 @2,8 GHz, linux guest using 4vcpus): 61.81 H/s at diff 5000
Virtual Machine(Host CPU: XEON X5540 @2,53 GHz, linux guest using 4vcpus):  68.49 H/s at diff 6629.01
Physical System (Windows Machine with XEON E5-2609 @2,4Ghz, using 3 threads): 88,8 H/s diff 5000

ive not done tuning and tests. The VMS/Servers are still usable because not all threads/core are used.

Total Hash rate vary between 180 and 400 H/sec. So ~0.01 Monero/day is currently a possible earning. If you dont pay 4 power let it run a few days as 1 Monero is currently worth ~80$.

I’ve read a blog describing mining Monero with Raspberry PIs, i really doubt that this cpu is strong enough to have a good Hashrate… (maybe 5-10 H/s)

For testing i added a GPU Miner and achieved up to 1,2 KH/sec. So yes.. GPU mining generates 10 times more Hash…

Physical System (Intel Core i7 / VTX3D Radeon R9 390, 8GB GDDR5 with wolf-xmr-miner-v0.4): ~600 H/s

 

Here’s a small howto 4 ubuntu:

  • Download CPU-Mining software for Linux here: https://github.com/fireice-uk/xmr-stak-cpu/releases
  • Debian/Ubuntu: apt-get install libcurl4-openssl-dev pkg-config automake autotools-dev automake build-essential
  • Unzip the Mining software and run autogen.sh
  • CFLAGS=“-march=native“ ./configure –disable-aes-ni
    (or if your cpu supports aes use: CFLAGS=“-march=native“ ./configure)
  • make
  • make install
  • run the miner via
    minerd -a cryptonight -o stratum+tcp://monerohash.com:3333 -u 43dNQfaUGzbPCaa1rkW4z5H7aN5M27rLhaodZULXTtPbN7XMQxixzPC6ouB6F6NWxLSkMQ4QhTo8VhKRiBh1E9AZKudNxSv -p x
    (you have to use your wallet id, if you want to leave the session start the miner with nohup command.

I had to impelement a MSSQL-Server 2016 with asynchronous mirroring.

So I followed every step written in several tutorials (like Restoring with NORECOVERY before Mirroring etc.). It seem that sthg was missing because I always got the Error 927 which means cannot access database because it gets restored… Seems logic but for Mirroring-Setup Database have to be in NORECOVERY State (means its not accessible and state is „restoring“).

 

After several days of re-installing, researching i finally solved it, with installing Microsoft SQL Management Studio 2014. I did the same as before and it worked without a problem.

The MSSQL 2014 Management Studio Installation should be here https://www.microsoft.com/de-DE/download/details.aspx?id=42299
