When you get the response “web.archive.org unexpectedly closed the connection” without even returning an HTTP code, but:
then likely there are too many cookies for archive.org or/and web.archive.org: in my case, I had 90 cookies.
Cleaning these cookies out resolved the problem (I used awesome cookie manager for this).

For my own memory:
[WayBack] Best Hard Drives for ZFS Server (Updated 2017) | b3n.org
ZFS, dedupe and RAM:
I wouldn’t worry so much about the cost of the drives if you have to replace them in a few years. They’re constantly getting bigger and cheaper. If you really need to replace them in 3 years it’s not going to be the end of the world. Just think, a 256GB SSD can be purchased for about $100 today and 3 years ago the same drives were like $400+. To boot, they are faster than they were 3 years ago.
It’s quite possible that by the time you need to be worried about buying replacement drives for your pool you’ll be able to buy a single drive that can hold 1/2 your pool’s data for $100.
Don’t fret it. Buy the SSDs and be happy. Tell your boss you did the analysis and all is well. Just don’t buy those TLC drives. Those seem very scary for ZFS IMO.
…
There are some companies that have forked ZFS and set it up as you describe (separate vdevs for metadata using high-endurance SLC NAND) but there’s nothing like that in OpenZFS at the moment.
I’ve been using it on Leap 42.2 for a while with no problems. Generally I’d guess it should work fine on Leap since it uses a stable LTS kernel.
On Tumbleweed you’d have problems if the kernel updates before the zfs on linux project has released an update version supporting that kernel. So tumbleweed (or any rolling distribution) + zfs certainly seems rather flaky to me.
…
What appeals to me is the ZFS scrub feature. Nothing else really seems to guard against bit-rot / corruption quite like this.
…
It’s not compatible with the new kernel yet. https://github.com/zfsonlinux/zfs/releases

A while ago, I somehow had a damaged btrfs partition that I found out after the virtualisation host without reason decided to reboot.
I’m not sure what caused that (by now the machine has been retired as it was already getting a bit old), but btrfs was panicking shortly after boot, so the VM as is was unusable.
In the end I had to:
rsync -avloz over as much as I could/etc tree and my home directory for which I hadn’t yet pushed the git repositories).These didn’t work, but might work for others: [WayBack] SDB:BTRFS – openSUSE – How to repair a broken/unmountable btrfs filesystem
