domain name system - Route 53 as backup to Cloudflare DNS

I use cloudflare as my main DNS provider right now but am looking to add route 53 as another provider/backup in case one or the other goes down. (DYN did this last year and it caused a headache with just one provider)

It is my understanding that I need to add the NS records to each domain and then update the name servers for each domain with my domain register.

Is this the best way to ensure uptime? Are there any issues with this?

Answer

I highly recommend reading the two links that EEAA commented, along with a third:

Essentially you have the right idea. Specify your additional nameservers as NS records in both of your zones (Route 53 and Cloudflare), and then add those new nameservers to your registrars configuration for your domain.

There will be zero downtime if you do this correctly.

The way to ensure you do this correctly is to use a tool like Stack Exchange's DNS Control to make the changes for you. Get it working with your current single DNS provider, and then just throw in the config to tell DNS Control to send the zone to multiple providers.

Note: I just saw in the comments that you are using orange-cloud with CloudFlare. An orange-cloud setup is totally incompatible with 3rd party DNS providers, as CloudFlare manipulates your served DNS records. This will only work for grey-cloud sites.

Don't let that put you off DNS Control though, as DNS Control has support for orange cloud control (just don't use dual DNS providers with orange cloud)

linux - iDRAC6 Virtual Media native library cannot be loaded

When attempting to mount Virtual Media on a iDRAC6 IP KVM session I get the following error: I'm using Ubuntu 9.04 and: $ javaws -version Java(TM) Web Start 1.6.0_16 $ uname -a Linux aud22419-linux 2.6.28-15-generic #51-Ubuntu SMP Mon Aug 31 13:39:06 UTC 2009 x86_64 GNU/Linux $ firefox -version Mozilla Firefox 3.0.14, Copyright (c) 1998 - 2009 mozilla.org On Windows + IE it (unsurprisingly) works. I've just gotten off the phone with the Dell tech support and I was told it is known to work on Linux + Firefox, albeit Ubuntu is not supported (by Dell, that is). Has anyone out there managed to mount virtual media in the same scenario?

ubuntu - Monitoring CPU, Mem, disk, on a single server

I've been looking for a simple starter solution for monitoring my [currently] single server hosted solution. Other than Nagios and similar, are there other good (simple) solutions people are using? Answer Everything depends on what you want. For example Munin is very simple, you can install and configure it in less then 10 minutes (on one server), it can sends alarms, make graphs from monitoring cpu, mem. apache connections, eaccellerator, disk io and many many more (it has many plugins). But if you are planning in future get some more machines, munin may not be enough. For example in munin you cant monitor state of individual processes, can't monitor changes in files (for security purpose). So if you wanna only see what is the utilization of basics parameters on your server and don't plan to buy some more servers Munin is what you are looking for, but if you wanna be alarmed when some of your service is down, take more control on what is happeninig on...

hp proliant - Smart Array P822 with HBA Mode?

We get an HP DL360 G8 with an Smart Array P822 controller. On that controller will come a HP StorageWorks D2700 . Does anybody know, that it is possible to run the Smart Array P822 in HBA mode? I found only information about the P410i, who can run HBA. If this is not supported, what you think about the LSI 9207-8e controller? Will this fit good in that setup? The Hardware we get is used but all original from HP. The StorageWorks has 25 x 900 GB SAS 10K disks. Because the disks are not new I would like to use only 22 for raid6, and the rest for spare (I need to see if the disk count is optimal or not for zfs). It would be nice if I'm not stick to SAS in future. As OS I would like to install debian stretch with zfs 0.71 as file system and software raid. I have see that hp has an page for debian to. I would like to use hba mode because it is recommend, that zfs know at most as possible about the disk, and I'm independent from the raid controller. For us zfs have many benefits, ...
