Step one is to remove the drives and clone them with dd or recovery tool to a new drive.
You could probably recover 99.9% of the data - if you want.

As you can guess from all of their previous issues, they don't want to pay for any recovery, they just want it magically fixed for free. They don't own any storage onto which to clone it, either.

Then what is the point of any of it? It appears to have zero value to the business.

I said that to them.

@StorageNinja said in Veeam with NetApp?:

Netapp E-Series is the same as the old Dell MD36xxx or the LSI enginio code base (IBM also sold a similar low-end modular array). These things were wicked fast/cost-effective at streaming workloads (got used for Lustre clusters a lot as the DAS on the nodes). Dell's abandoned reselling them for Seagate (Dothill) but they still around

Not wicked fast compared to building your own. And the staggering lack of internal support if anything goes wrong is a big deal... storage is one of those things you want to have work, especially at these price ranges. Having been a NetApp customer, I know that their support is helpless when it comes to trying to do high performance, their crap just falls over and so do their engineers.

metadata?

please explain more.

The config files where the vm is defined. Do not backup the vm disk only. I suppose he referes to this.

I backup with veeam.
whole vm files.

I don't know how Starwind vSAN can be run but if it's on a hypervisor it's severely limited by I/O congestion through the kernel. NVMe drives is causing problems that was of no concern whatsoever with spinners. Both KVM and Xen has made a lot of work to limit their I/O latency and use polling techniques now but it's still a problem. That's why you really need SR-IOV on NVMe drives so any VM can bypass the hypervisor and just have it's own kernel to slow things down.

Anton: There are no problems with polling these days 🙂 You normally spawn a SPDK-enabled VM (Linux is unbeatable here as most of the new gen I/O development happens there) and pass thru RDMA-capable network hardware (virtual function with SR-IOV or whole card with PCIe pass-thru, this is really irrelevant...) and NMVe drives and... magic starts happening 🙂 This is how our NVMe-oF target works on ESXi & Hyper-V (KVM & Xen have no benefits here architecturally, this is where you're either wrong or I failed to get your arguments). It's possible to port SPDK into Windows user-mode but lack of NVMe and NIC polling drivers takes away all the fun: to move the same amount of data we normally use ~4x more CPU horsepower on "Pure Windows" Vs. "Linux-SPDK-VM-on-Windows" models. Microsoft is trying to bring SPDK to Windows kernel (so does VMware from what I know), but it needs a lot of work from NIC and NVMe engineers and... nobody wants to contribute. Really.

Just my $0.02 🙂

@marcinozga said in Linux users with iPhones / iPads:

@NashBrydges That's most likely direct connection. Plex uses UPnP and NAT-PMP to open ports on router, otherwise you simply cannot connect directly. If you stream through relay, that's where limitation is in place.

I have UPNP + NAT-PMP enabled. I'll disable them and test things out when I have a chance.

Interesting but also I get confused with all the comments XD

I am seriously thinking about buy a SSD drive to install on my old computer that is Pentium 4 - 3.0 GHz, 3 GB RAM, with Windows XP and install there the Windows 10 so it can run faster, Do you think that is a crazy idea?

Yes, it's crazy. Even if you can get a $30 SSD like we can from Amazon here in the US (small WD Green drive), it's not worth putting $30 into a computer worth at best $5.

Pentium 4 wasn't just a 32bit processor, it was a really, really slow 32bit processor. It was so bad that they had to bring the Pentium 3 back with a new name to keep their products alive while they figured out what to do. It's considered the worst processor ever made (that got actually sold.) And with only 3GB of RAM, it doesn't have anything there going for it, either.

It's only $55 if you shop around to get a quad core, 64bit, 8GB RAM Raspberry Pi. If you are going to talk about adding an SSD to something, start with at least that.

Is using a RAID 1 configuration faster as well? Or is its main purpose so if you lose one of the drives you have a backup?

Primary purpose is definitely data protection. But RAID 1 provides a 200% read performance benefit over using a single drive. Write performance is the same as a single drive.

@connorsoliver said in An Overview of Storage Devices - CompTIA A+ 220-901 220-902 Video Training by Prof. Messer:

What did he mean when he said there's only a limited number or writes on a USB flash drive.

So this is a small mistake on the A+ material. They are making assumptions about the storage media based on the communications protocol. But it's based on very common things. A standard USB flash drive using a flash memory technology that "wears out" as you write to it, but essentially never wears out as you read it.

So the way that a USB stick is "meant to be used" is that you store things on it and read it a lot. You can change it, but it isn't meant for constant writes.

So under "normal" use, USB sticks last a long time. But it you write to it constantly (like when using it as swap) you will cause the memory chip(s) to die quickly.

@dafyre said in How would you build a File server with 170TB of Usable Storage?:

Systems like Ceph and Gluster don't necessarily need RAID since they can work with different disks in the same node.

They definitely don't need RAID. That's their point.
